[PATCH v3] riscv: set max_pfn to the PFN of the last page

The current max_pfn equals to zero. In this case, I found it caused users cannot get some page information through /proc such as kpagecount in v5.6 kernel because of new sanity checks. The following message is displayed by stress-ng test suite with the command "stress-ng --verbose --physpage 1 -t 1" on HiFive unleashed board. # stress-ng --verbose --physpage 1 -t 1 stress-ng: debug: [109] 4 processors online, 4 processors configured stress-ng: info: [109] dispatching hogs: 1 physpage stress-ng: debug: [109] cache allocate: reducing cache level from L3 (too high) to L0 stress-ng: debug: [109] get_cpu_cache: invalid cache_level: 0 stress-ng: info: [109] cache allocate: using built-in defaults as no suitable cache found stress-ng: debug: [109] cache allocate: default cache size: 2048K stress-ng: debug: [109] starting stressors stress-ng: debug: [109] 1 stressor spawned stress-ng: debug: [110] stress-ng-physpage: started [110] (instance 0) stress-ng: error: [110] stress-ng-physpage: cannot read page count for address 0x3fd34de000 in /proc/kpagecount, errno=0 (Success) stress-ng: error: [110] stress-ng-physpage: cannot read page count for address 0x3fd32db078 in /proc/kpagecount, errno=0 (Success) ... stress-ng: error: [110] stress-ng-physpage: cannot read page count for address 0x3fd32db078 in /proc/kpagecount, errno=0 (Success) stress-ng: debug: [110] stress-ng-physpage: exited [110] (instance 0) stress-ng: debug: [109] process [110] terminated stress-ng: info: [109] successful run completed in 1.00s # After applying this patch, the kernel can pass the test. # stress-ng --verbose --physpage 1 -t 1 stress-ng: debug: [104] 4 processors online, 4 processors configured stress-ng: info: [104] dispatching hogs: 1 physpage stress-ng: info: [104] cache allocate: using defaults, can't determine cache details from sysfs stress-ng: debug: [104] cache allocate: default cache size: 2048K stress-ng: debug: [104] starting stressors stress-ng: debug: [104] 1 stressor spawned stress-ng: debug: [105] stress-ng-physpage: started [105] (instance 0) stress-ng: debug: [105] stress-ng-physpage: exited [105] (instance 0) stress-ng: debug: [104] process [105] terminated stress-ng: info: [104] successful run completed in 1.01s # Fixes: 0651c263c8e3 (RISC-V: Move setup_bootmem() to mm/init.c) Cc: stable(a)vger.kernel.org Signed-off-by: Vincent Chen <vincent.chen(a)sifive.com> Reviewed-by: Anup Patel <anup(a)brainfault.org> Reviewed-by: Yash Shah <yash.shah(a)sifive.com> Tested-by: Yash Shah <yash.shah(a)sifive.com> Changes since v1: 1.

[PATCH 1/3] bfq: Avoid false bfq queue merging

by Jan Kara

bfq_setup_cooperator() uses bfqd->in_serv_last_pos so detect whether it makes sense to merge current bfq queue with the in-service queue. However if the in-service queue is freshly scheduled and didn't dispatch any requests yet, bfqd->in_serv_last_pos is stale and contains value from the previously scheduled bfq queue which can thus result in a bogus decision that the two queues should be merged. This bug can be observed for example with the following fio jobfile: [global] direct=0 ioengine=sync invalidate=1 size=1g rw=read [reader] numjobs=4 directory=/mnt where the 4 processes will end up in the one shared bfq queue although they do IO to physically very distant files (for some reason I was able to observe this only with slice_idle=1ms setting). Fix the problem by invalidating bfqd->in_serv_last_pos when switching in-service queue.

[BACKPORT] xen/pvh: correctly setup the PV EFI interface for dom0

by Roger Pau Monne

commit 72813bfbf0276a97c82af038efb5f02dcdd9e310 upstream This involves initializing the boot params EFI related fields and the efi global variable. Without this fix a PVH dom0 doesn't detect when booted from EFI, and thus doesn't support accessing any of the EFI related data.

[PATCH v3 0/6] Memory corruption may occur due to incorrent tlb flush

by Santosh Sivaraj

The TLB flush optimisation (a46cc7a90f: powerpc/mm/radix: Improve TLB/PWC flushes) may result in random memory corruption. Any concurrent page-table walk could end up with a Use-after-Free. Even on UP this might give issues, since mmu_gather is preemptible these days. An interrupt or preempted task accessing user pages might stumble into the free page if the hardware caches page directories. The series is a backport of the fix sent by Peter [1]. The first three patches are dependencies for the last patch (avoid potential double flush). If the performance impact due to double flush is considered trivial then the first three patches and last patch may be dropped. This is only for v4.19 stable.

[PATCH 4.19 1/7] mm: drop meminit_pfn_in_nid as it is redundant

by Pavel Tatashin

From: Alexander Duyck <alexander.h.duyck(a)linux.intel.com> From: Alexander Duyck <alexander.h.duyck(a)linux.intel.com> commit 56ec43d8b02719402c9fcf984feb52ec2300f8a5 upstream. As best as I can tell the meminit_pfn_in_nid call is completely redundant. The deferred memory initialization is already making use of for_each_free_mem_range which in turn will call into __next_mem_range which will only return a memory range if it matches the node ID provided assuming it is not NUMA_NO_NODE. I am operating on the assumption that there are no zones or pgdata_t structures that have a NUMA node of NUMA_NO_NODE associated with them. If that is the case then __next_mem_range will never return a memory range that doesn't match the zone's node ID and as such the check is redundant. So one piece I would like to verify on this is if this works for ia64. Technically it was using a different approach to get the node ID, but it seems to have the node ID also encoded into the memblock. So I am assuming this is okay, but would like to get confirmation on that. On my x86_64 test system with 384GB of memory per node I saw a reduction in initialization time from 2.80s to 1.85s as a result of this patch.

[PATCH] arm64: don't preempt_disable in do_debug_exception

by Paul Gortmaker

In commit d8bb6718c4db ("arm64: Make debug exception handlers visible from RCU") debug_exception_enter and exit were added to deal with better tracking of RCU state - however, in addition to that, but not mentioned in the commit log, a preempt_disable/enable pair were also added. Based on the comment (being removed here) it would seem that the pair were not added to address a specific problem, but just as a proactive, preventative measure - as in "seemed like a good idea at the time". The problem is that do_debug_exception() eventually calls out to generic kernel code like do_force_sig_info() which takes non-raw locks and on -rt enabled kernels, results in things looking like the following, since on -rt kernels, it is noticed that preemption is still disabled. BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:975 in_atomic(): 1, irqs_disabled(): 0, pid: 35658, name: gdbtest Preemption disabled at: [<ffff000010081578>] do_debug_exception+0x38/0x1a4 Call trace: dump_backtrace+0x0/0x138 show_stack+0x24/0x30 dump_stack+0x94/0xbc ___might_sleep+0x13c/0x168 rt_spin_lock+0x40/0x80 do_force_sig_info+0x30/0xe0 force_sig_fault+0x64/0x90 arm64_force_sig_fault+0x50/0x80 send_user_sigtrap+0x50/0x80 brk_handler+0x98/0xc8 do_debug_exception+0x70/0x1a4 el0_dbg+0x18/0x20 The reproducer was basically an automated gdb test that set a breakpoint on a simple "hello world" program and then quit gdb once the breakpoint was hit - i.e. "(gdb) A debugging session is active.
