This is a note to let you know that I've just added the patch titled xhci: Add missing CAS workaround for Intel Sunrise Point xHCI to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From ffe84e01bb1b38c7eb9c6b6da127a6c136d251df Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Mon, 1 Oct 2018 18:36:07 +0300 Subject: xhci: Add missing CAS workaround for Intel Sunrise Point xHCI The workaround for missing CAS bit is also needed for xHC on Intel sunrisepoint PCH.

When the configuration is updated and interfaces are added/removed, the interface numbers are updated. This causes our current code for matching EP06 not to work as intended, as the assumption about reserved interfaces no longer holds. If for example the diagnostic (first) interface is removed, option will (try to) bind to the QMI interface. This patch improves EP06 detection by replacing the current match with two matches, and those matches check class, subclass and protocol as well as VID and PID. The diag interface exports class, subclass and protocol as 0xff. For the other serial interfaces, class is 0xff and subclass and protocol are both 0x0. The modem can export the following devices and always in this order: diag, nmea, at, ppp. qmi and adb. This means that diag can only ever be interface 0, and interface numbers 1-5 should be marked as reserved. The three other serial devices can have interface numbers 0-3, but I have not marked any interfaces as reserved. The reason is that the serial devices are the only interfaces exported by the device where subclass and protocol is 0x0. QMI exports the same class, subclass and protocol values as the diag interface. However, the two interfaces have different number of endpoints, QMI has three and diag two. I have added a check for number of interfaces if VID/PID matches the EP06, and we ignore the device if number of interfaces equals three (and subclass is set).

patch "USB: serial: option: add two-endpoints device-id flag" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: option: add two-endpoints device-id flag to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 35aecc02b5b621782111f64cbb032c7f6a90bb32 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Thu, 13 Sep 2018 11:21:50 +0200 Subject: USB: serial: option: add two-endpoints device-id flag Allow matching on interfaces having two endpoints by adding a new device-id flag.

by Sasha Levin

From: Martin Willi <martin(a)strongswan.org> [ Upstream commit c1dc2912059901f97345d9e10c96b841215fdc0f ] The cluster match requires conntrack for matching packets.

[PATCH] kdb: print real address of pointers instead of hashed addresses

by Christophe Leroy

Since commit ad67b74d2469 ("printk: hash addresses printed with %p"), all pointers printed with %p are printed with hashed addresses instead of real addresses in order to avoid leaking addresses in dmesg and syslog. But this applies to kdb too, with is unfortunate: Entering kdb (current=0x(ptrval), pid 329) due to Keyboard Entry kdb> ps 15 sleeping system daemon (state M) processes suppressed, use 'ps A' to see all. Task Addr Pid Parent [*] cpu State Thread Command 0x(ptrval) 329 328 1 0 R 0x(ptrval) *sh 0x(ptrval) 1 0 0 0 S 0x(ptrval) init 0x(ptrval) 3 2 0 0 D 0x(ptrval) rcu_gp 0x(ptrval) 4 2 0 0 D 0x(ptrval) rcu_par_gp 0x(ptrval) 5 2 0 0 D 0x(ptrval) kworker/0:0 0x(ptrval) 6 2 0 0 D 0x(ptrval) kworker/0:0H 0x(ptrval) 7 2 0 0 D 0x(ptrval) kworker/u2:0 0x(ptrval) 8 2 0 0 D 0x(ptrval) mm_percpu_wq 0x(ptrval) 10 2 0 0 D 0x(ptrval) rcu_preempt The whole purpose of kdb is to debug, and for debugging real addresses need to be known. In addition, data displayed by kdb doesn't go into dmesg. This patch replaces all %p by %px in kdb in order to display real addresses.

[PATCH 1/2] x86/vdso: Fix asm constraints on vDSO syscall fallbacks

by Andy Lutomirski

The syscall fallbacks in the vDSO have incorrect asm constraints. They are not marked as writing to their outputs -- instead, they are marked as clobbering "memory", which is useless. In particular, gcc is smart enough to know that the timespec parameter hasn't escaped, so a memory clobber doesn't clobber it. And passing a pointer as an asm *input* does not tell gcc that the pointed-to value is changed. Add in the fact that the asm instructions weren't volatile, and gcc was free to omit them entirely unless their sole output (the return value) is used. Which it is (phew!), but that stops happening with some upcoming patches. As a trivial example, the following code: void test_fallback(struct timespec *ts) { vdso_fallback_gettime(CLOCK_MONOTONIC, ts); } compiles to: 00000000000000c0 <test_fallback>: c0: c3 retq To add insult to injury, the RCX and R11 clobbers on 64-bit builds were missing. The "memory" clobber is also unnecessary -- no ordering with respect to other memory operations is needed, but I'll fix that in a separate not-for-stable patch.

[RFT PATCH 1/2] xhci: Fix leaking USB3 shared_hcd at xhci removal

by Mathias Nyman

Ensure that the shared_hcd pointer is valid when calling usb_put_hcd() The shared_hcd is removed and freed in xhci by first calling usb_remove_hcd(xhci->shared_hcd), and later usb_put_hcd(xhci->shared_hcd) Afer commit fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.") the shared_hcd was never properly put as xhci->shared_hcd was set to NULL before usb_put_hcd(xhci->shared_hcd) was called. shared_hcd (USB3) is removed before primary hcd (USB2). While removing the primary hcd we might need to handle xhci interrupts to cleanly remove last USB2 devices, therefore we need to set xhci->shared_hcd to NULL before removing the primary hcd to let xhci interrupt handler know shared_hcd is no longer available. xhci-plat.c, xhci-histb.c and xhci-mtk first create both their hcd's before adding them. so to keep the correct reverse removal order use a temporary shared_hcd variable for them. For more details see commit 4ac53087d6d4 ("usb: xhci: plat: Create both HCDs before adding them") Fixes: fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.")

A NMI-only lock tried to be acquired with xen_qlock_wait() for another lock having been interrupted by the NMI will be enough to risk the issue. So yes, I believe the test for NMI is good to have.

[PATCH 1/2] xen: fix race in xen_qlock_wait()

by Juergen Gross

In the following situation a vcpu waiting for a lock might not be woken up from xen_poll_irq(): CPU 1: CPU 2: CPU 3: takes a spinlock tries to get lock -> xen_qlock_wait() -> xen_clear_irq_pending() frees the lock -> xen_qlock_kick(cpu2) takes lock again tries to get lock -> *lock = _Q_SLOW_VAL -> *lock == _Q_SLOW_VAL ? -> xen_poll_irq() frees the lock -> xen_qlock_kick(cpu3) And cpu 2 will sleep forever. This can be avoided easily by modifying xen_qlock_wait() to call xen_poll_irq() only if the related irq was not pending and to call xen_clear_irq_pending() only if it was pending.

[PATCH stable v4.17] PCI: aardvark: Size bridges before resources allocation

by Thomas Petazzoni

From: Zachary Zhang <zhangzg(a)marvell.com> commit 91a2968e245d6ba616db37001fa1a043078b1a65 usptream. The PCIE I/O and MEM resource allocation mechanism is that root bus goes through the following steps: 1. Check PCI bridges' range and computes I/O and Mem base/limits. 2. Sort all subordinate devices I/O and MEM resource requirements and allocate the resources and writes/updates subordinate devices' requirements to PCI bridges I/O and Mem MEM/limits registers. Currently, PCI Aardvark driver only handles the second step and lacks the first step, so there is an I/O and MEM resource allocation failure when using a PCI switch. This commit fixes that by sizing bridges before doing the resource allocation.

[PATCH AUTOSEL 4.14 01/37] netfilter: xt_cluster: add dependency on conntrack module

by Sasha Levin

From: Martin Willi <martin(a)strongswan.org> [ Upstream commit c1dc2912059901f97345d9e10c96b841215fdc0f ] The cluster match requires conntrack for matching packets.

patch "tools: hv: fcopy: set 'error' in case an unknown operation was" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tools: hv: fcopy: set 'error' in case an unknown operation was to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.

Please apply 2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") to 3.18.y

by Greg Hackmann

2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") was applied to 4.4.y a couple of weeks ago, and is needed on 3.18.y too. The patch cherry-picks and builds as-is on top of 3.18.123.

[PATCH v4.4.y] ext4: never move the system.data xattr out of the inode body

by Zubin Mithra

From: Theodore Ts'o <tytso(a)mit.edu> commit 8cdb5240ec5928b20490a2bb34cb87e9a5f40226 upstream. When expanding the extra isize space, we must never move the system.data xattr out of the inode body. For performance reasons, it doesn't make any sense, and the inline data implementation assumes that system.data xattr is never in the external xattr block. This addresses CVE-2018-10880 https://bugzilla.kernel.org/show_bug.cgi?id=200005 Backport Note: - dfa2064b22("ext4: factor out loop for freeing inode xattr space") factored out the loop from inside ext4_expand_extra_isize_ea to a separate function named ext4_xattr_make_inode_space. As the above commit is not present in 4.4.y, make the change inside ext4_expand_extra_isize_ea.

This wait should be momentary. During a link down event, the cleanup handling does not ensure that all packets caught by the link down are flushed properly. This is caused by the fact that the freeze path and the link down event is handled the same. This is not correct. The freeze path waits until the HFI is unfrozen and then restarts PIO. A link down is not a freeze event. The link down path cannot restart the PIO until link is restored. If the PIO path is restarted before the link comes up, the application (QP) using the PIO path will hang (until link is restored). Fix by separating the linkdown path from the freeze path and use the link down path for link down events. Close a race condition sc_disable() by acquiring both the progress and release locks. Close a race condition in sc_stop() by moving the setting of the flag bits under the alloc lock.

If a lane is disabled, adding a packet to the send context must be disallowed. The current mask for determining unsupported VLs defaults to 0 (allow all). This is incorrect. Only the VLs that are defined should be allowed. Determine which VLs are disabled (mtu == 0), and set the appropriate unsupported bit in the mask. The correct mask will allow the send engine to error on the invalid VL, and error recovery will work correctly.

[PATCH] media: uvcvideo: Support UVC 1.5 video probe & commit controls

by Laurent Pinchart

From: ming_qian <ming_qian(a)realsil.com.cn> commit f620d1d7afc7db57ab59f35000752840c91f67e7 upstream. The length of UVC 1.5 video control is 48, and it is 34 for UVC 1.1. Change it to 48 for UVC 1.5 device, and the UVC 1.5 device can be recognized. More changes to the driver are needed for full UVC 1.5 compatibility. However, at least the UVC 1.5 Realtek RTS5847/RTS5852 cameras have been reported to work well.

Currently the static fixmap setup in head_64.S only covers 2M virtual address space, while it actually could be in 4M space with different kernel configurations, e.g. when VSYSCALL emulation is disabled.

FAILED: patch "[PATCH] block: use nanosecond resolution for iostat" failed to apply to 4.18-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.18-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b57e99b4b8b0ebdf9707424e7ddc0c392bdc5fe6 Mon Sep 17 00:00:00 2001 From: Omar Sandoval <osandov(a)fb.com> Date: Fri, 21 Sep 2018 16:44:34 -0700 Subject: [PATCH] block: use nanosecond resolution for iostat Klaus Kusche reported that the I/O busy time in /proc/diskstats was not updating properly on 4.18. This is because we started using ktime to track elapsed time, and we convert nanoseconds to jiffies when we update the partition counter. However, this gets rounded down, so any I/Os that take less than a jiffy are not accounted for. Previously in this case, the value of jiffies would sometimes increment while we were doing I/O, so at least some I/Os were accounted for. Let's convert the stats to use nanoseconds internally. We still report milliseconds as before, now more accurately than ever. The value is still truncated to 32 bits for backwards compatibility.

[PATCH 1/2] iio: adc: at91: fix acking DRDY irq on simple conversions

by Eugen Hristev

When doing simple conversions, the driver did not acknowledge the DRDY irq. If this irq is not acked, it will be left pending, and as soon as a trigger is enabled, the irq handler will be called, it doesn't know why this irq has occurred because no channel is pending, and then we will have irq loop and board will hang.

[PATCH 1/2] of/fdt: Allow architectures to override CONFIG_CMDLINE logic

by Paul Burton

The CONFIG_CMDLINE-related logic in early_init_dt_scan_chosen() falls back to copying CONFIG_CMDLINE into boot_command_line/data if the DT has a /chosen node but that node has no bootargs property or a bootargs property of length zero. This is problematic for the MIPS architecture because we support concatenating arguments from either the DT or the bootloader with those from CONFIG_CMDLINE, but the behaviour of early_init_dt_scan_chosen() gives us no way of knowing whether boot_command_line contains arguments from DT or already contains CONFIG_CMDLINE. This can lead to us concatenating CONFIG_CMDLINE with itself, duplicating command line arguments which can be problematic (eg. for earlycon which will attempt to register the same console twice & warn about it). Move the CONFIG_CMDLINE-related logic to a weak function that architectures can provide their own version of, such that we continue to use the existing logic for architectures where it's suitable but also allow MIPS to override this behaviour such that the architecture code knows when CONFIG_CMDLINE is used.

ovl: hash non-dir by lower inode for fsnotify

by Mark Salyzyn

(cherry pick from commit 764baba80168ad3adafb521d2ab483ccbc49e344) Commit 31747eda41ef ("ovl: hash directory inodes for fsnotify") fixed an issue of inotify watch on directory that stops getting events after dropping dentry caches. A similar issue exists for non-dir non-upper files, for example: $ mkdir -p lower upper work merged $ touch lower/foo $ mount -t overlay -o lowerdir=lower,workdir=work,upperdir=upper none merged $ inotifywait merged/foo & $ echo 2 > /proc/sys/vm/drop_caches $ cat merged/foo inotifywait doesn't get the OPEN event, because ovl_lookup() called from 'cat' allocates a new overlay inode and does not reuse the watched inode. Fix this by hashing non-dir overlay inodes by lower real inode in the following cases that were not hashed before this change: - A non-upper overlay mount - A lower non-hardlink when index=off A helper ovl_hash_bylower() was added to put all the logic and documentation about which real inode an overlay inode is hashed by into one place. The issue dates back to initial version of overlayfs, but this patch depends on ovl_inode code that was introduced in kernel v4.13.

[PATCH] keys: Fix the use of the C++ keyword "private" in uapi/linux/keyctl.h

by David Howells

The keyctl_dh_params struct in uapi/linux/keyctl.h contains the symbol "private" which means that the header file will cause compilation failure if #included in to a C++ program. Further, the patch that added the same struct to the keyutils package named the symbol "priv", not "private". The previous attempt to fix this (commit 8a2336e549d3) did so by simply renaming the kernel's copy of the field to dh_private, but this then breaks existing userspace and as such has been reverted (commit 8c0f9f5b309d). [And note, to those who think that wrapping the struct in extern "C" {} will work: it won't; that only changes how symbol names are presented to the assembler and linker.]. Instead, insert an anonymous union around the "private" member and add a second member in there with the name "priv" to match the one in the keyutils package. The "private" member is then wrapped in !__cplusplus cpp-conditionals to hide it from C++.

[PATCH] platform-msi: Free descriptors in platform_msi_domain_free()

by Miquel Raynal

Since the addition of platform MSI support, there were two helpers supposed to allocate/free IRQs for a device: platform_msi_domain_alloc_irqs() platform_msi_domain_free_irqs() In these helpers, IRQ descriptors are allocated in the "alloc" routine while they are freed in the "free" one. Later, two other helpers have been added to handle IRQ domains on top of MSI domains: platform_msi_domain_alloc() platform_msi_domain_free() Seen from the outside, the logic is pretty close with the former helpers and people used it with the same logic as before: a platform_msi_domain_alloc() call should be balanced with a platform_msi_domain_free() call. While this is probably what was intended to do, the platform_msi_domain_free() does not remove/free the IRQ descriptor(s) created/inserted in platform_msi_domain_alloc(). One effect of such situation is that removing a module that requested an IRQ will let one orphaned IRQ descriptor (with an allocated MSI entry) in the device descriptors list. Next time the module will be inserted back, one will observe that the allocation will happen twice in the MSI domain, one time for the remaining descriptor, one time for the new one. It also has the side effect to quickly overshoot the maximum number of allocated MSI and then prevent any module requesting an interrupt in the same domain to be inserted anymore. This situation has been met with loops of insertion/removal of the mvpp2.ko module (requesting 15 MSIs each time).

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. The Clear Linux container is building with NO_CLANG=1, the problem preventing its use when building for python3 has been identified and the next builds will build in ClearLinux with both gcc and clang.

[STABLE PATCH] slub: make ->cpu_partial unsigned int

by zhong jiang

From: Alexey Dobriyan <adobriyan(a)gmail.com> /* * cpu_partial determined the maximum number of objects * kept in the per cpu partial lists of a processor. */ Can't be negative. I hit a real issue that it will result in a large number of memory leak. Because Freeing slabs are in interrupt context. So it can trigger this issue. put_cpu_partial can be interrupted more than once. due to a union struct of lru and pobjects in struct page, when other core handles page->lru list, for eaxmple, remove_partial in freeing slab code flow, It will result in pobjects being a negative value(0xdead0000). Therefore, a large number of slabs will be added to per_cpu partial list. I had posted the issue to community before. The detailed issue description is as follows. Link: https://www.spinics.net/lists/kernel/msg2870979.html After applying the patch, The issue is fixed. So the patch is a effective bugfix. It should go into stable.

[PATCH] mtd: rawnand: marvell: check for RDY bits after enabling the IRQ

by Daniel Mack

At least on PXA3xx platforms, enabling RDY interrupts in the NDCR register will only cause the IRQ to latch when the RDY lanes are changing, and not in case they are already asserted. This means that if the controller finished the command in flight before marvell_nfc_wait_op() is called, that function will wait for a change in the bit that can't ever happen as it is already set. To mitigate this race, check for the RDY bits after the IRQ was enabled, and only sleep on the condition if the controller isn't ready yet. This fixes a bug that was observed with a NAND chip that holds a UBIFS parition on which file system stress tests were executed. When marvell_nfc_wait_op() reports an error, UBI/UBIFS will eventually mount the filesystem read-only, reporting lots of warnings along the way.

[PATCH AUTOSEL 4.9 01/57] crypto: skcipher - Fix -Wstringop-truncation warnings

by Sasha Levin

[PATCH v2] rseq/selftests: fix parametrized test with -fpie

by Mathieu Desnoyers

On x86-64, the parametrized selftest code for rseq crashes with a segmentation fault when compiled with -fpie. This happens when the param_test binary is loaded at an address beyond 32-bit on x86-64. The issue is caused by use of a 32-bit register to hold the address of the loop counter variable. Fix this by using a 64-bit register to calculate the address of the loop counter variables as an offset from rip.

[PATCH] MIPS: VDSO: Always map near top of user memory

by Paul Burton

When using the legacy mmap layout, for example triggered using ulimit -s unlimited, get_unmapped_area() fills memory from bottom to top starting from a fairly low address near TASK_UNMAPPED_BASE. This placement is suboptimal if the user application wishes to allocate large amounts of heap memory using the brk syscall. With the VDSO being located low in the user's virtual address space, the amount of space available for access using brk is limited much more than it was prior to the introduction of the VDSO. For example: # ulimit -s unlimited; cat /proc/self/maps 00400000-004ec000 r-xp 00000000 08:00 71436 /usr/bin/coreutils 004fc000-004fd000 rwxp 000ec000 08:00 71436 /usr/bin/coreutils 004fd000-0050f000 rwxp 00000000 00:00 0 00cc3000-00ce4000 rwxp 00000000 00:00 0 [heap] 2ab96000-2ab98000 r--p 00000000 00:00 0 [vvar] 2ab98000-2ab99000 r-xp 00000000 00:00 0 [vdso] 2ab99000-2ab9d000 rwxp 00000000 00:00 0 ... Resolve this by adjusting STACK_TOP to reserve space for the VDSO & providing an address hint to get_unmapped_area() causing it to use this space even when using the legacy mmap layout. We reserve enough space for the VDSO, plus 1MB or 8MB for 32 bit & 64 bit systems respectively within which we randomize the VDSO base address. Previously this randomization was taken care of by the mmap base address randomization performed by arch_mmap_rnd(). The 1MB & 8MB sizes are somewhat arbitrary but chosen such that we have some randomization without taking up too much of the user's virtual address space, which is often in short supply for 32 bit systems. With this the VDSO is always mapped at a high address, leaving lots of space for statically linked programs to make use of brk: # ulimit -s unlimited; cat /proc/self/maps 00400000-004ec000 r-xp 00000000 08:00 71436 /usr/bin/coreutils 004fc000-004fd000 rwxp 000ec000 08:00 71436 /usr/bin/coreutils 004fd000-0050f000 rwxp 00000000 00:00 0 00c28000-00c49000 rwxp 00000000 00:00 0 [heap] ... 7f67c000-7f69d000 rwxp 00000000 00:00 0 [stack] 7f7fc000-7f7fd000 rwxp 00000000 00:00 0 7fcf1000-7fcf3000 r--p 00000000 00:00 0 [vvar] 7fcf3000-7fcf4000 r-xp 00000000 00:00 0 [vdso] Signed-off-by: Paul Burton <paul.burton(a)mips.com> Reported-by: Huacai Chen <chenhc(a)lemote.com> Fixes: ebb5e78cc634 ("MIPS: Initial implementation of a VDSO") Cc: Huacai Chen <chenhc(a)lemote.com> Cc: linux-mips(a)linux-mips.org Cc: stable(a)vger.kernel.org # v4.4+ --- Huacai, could you test if this fixes your problem?

On a powerpc 8xx, 'btc' fails as follows: Entering kdb (current=0x(ptrval), pid 282) due to Keyboard Entry kdb> btc btc: cpu status: Currently on cpu 0 Available cpus: 0 kdb_getarea: Bad address 0x0 when booting the kernel with 'debug_boot_weak_hash', it fails as well Entering kdb (current=0xba99ad80, pid 284) due to Keyboard Entry kdb> btc btc: cpu status: Currently on cpu 0 Available cpus: 0 kdb_getarea: Bad address 0xba99ad80 On other platforms, Oopses have been observed too, see https://github.com/linuxppc/linux/issues/139 This is due to btc calling 'btt' with %p pointer as an argument. This patch replaces %p by %px to get the real pointer value as expected by 'btt' Fixes: ad67b74d2469 ("printk: hash addresses printed with %p") Cc: <stable(a)vger.kernel.org> Reviewed-by: Daniel Thompson <daniel.thompson(a)linaro.org> Signed-off-by: Christophe Leroy <christophe.leroy(a)c-s.fr> --- v2: Added fixes: and Daniel's reviewed-by: in commit's log.

[PATCH 3.18.y 0/2] HID: sony: backport DualShock 4 device ids

by Roderick Colenbrander

Hi, We would like to request inclusion of updated DualShock 4 device ids for hid-sony in Linux 3.18. Existing devices on older kernels already support the original DualShock 4, but not recent hardware revisions. A similar backport was submitted for 4.4/4.9. Kernels newer than 4.12 already include these patches. The patches were cherry-picked from upstream and modified to apply cleanly and compile.

[PATCH 1/1] bcache: add separate workqueue for journal_write to avoid deadlock

by Coly Li

From: guoju <fangguoju(a)gmail.com> After write SSD completed, bcache schedules journal_write work to system_wq, which is a public workqueue in system, without WQ_MEM_RECLAIM flag. system_wq is also a bound wq, and there may be no idle kworker on current processor. Creating a new kworker may unfortunately need to reclaim memory first, by shrinking cache and slab used by vfs, which depends on bcache device. That's a deadlock. This patch create a new workqueue for journal_write with WQ_MEM_RECLAIM flag. It's rescuer thread will work to avoid the deadlock.

[PATCH 2/3] pinctrl: mcp23s08: fix irq and irqchip setup order

by Marco Felsch

Since 'commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' the irq request isn't the last devm_* allocation. Without a deeper look at the irq and testing this isn't a good solution. Since this driver relies on the devm mechanism, requesting a interrupt should be the last thing to avoid memory corruptions during unbinding. 'Commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' fixed the order for the interrupt-controller use case only. The mcp23s08_irq_setup() must be split into two to fix it for the interrupt-controller use case and to register the irq at last. So the irq will be freed first during unbind.
