The syzkaller folks reported a nested_run_pending warning during userspace
clear VMX capability which is exposed to L1 before.
The warning gets thrown while doing
(*(uint32_t*)0x20aecfe8 = (uint32_t)0x1);
(*(uint32_t*)0x20aecfec = (uint32_t)0x0);
(*(uint32_t*)0x20aecff0 = (uint32_t)0x3a);
(*(uint32_t*)0x20aecff4 = (uint32_t)0x0);
(*(uint64_t*)0x20aecff8 = (uint64_t)0x0);
r[29] = syscall(__NR_ioctl, r[4], 0x4008ae89ul,
0x20aecfe8ul, 0, 0, 0, 0, 0, 0);
i.e. KVM_SET_MSR ioctl with
struct kvm_msrs {
.nmsrs = 1,
.pad = 0,
.entries = {
{.index = MSR_IA32_FEATURE_CONTROL,
.reserved = 0,
.data = 0}
}
}
The VMLANCH/VMRESUME emulation should be stopped since the CPU is going to
reset here. This patch resets the nested_run_pending since the CPU is going
to be reset hence there should be nothing pending.

Subject: kbuild: pkg: use --transform option to prefix paths in tar
From: Masahiro Yamada <yamada.masahiro(a)socionext.com>
[ Upstream commit 2dbc644ac62bbcb9ee78e84719953f611be0413d ]
For rpm-pkg and deb-pkg, a source tar file is created. All paths in
the archive must be prefixed with the base name of the tar so that
everything is contained in the directory when you extract it.
Currently, scripts/package/Makefile uses a symlink for that, and
removes it after the tar is created.
If you terminate the build during the tar creation, the symlink is
left over. Then, at the next package build, you will see a warning
like follows:
ln: '.' and 'kernel-4.14.0+/.' are the same file
It is possible to fix it by adding -n (--no-dereference) option to
the "ln" command, but a cleaner way is to use --transform option
of "tar" command. This option is GNU extension, but it should not
hurt to use it in the Linux build system.
The 'S' flag is needed to exclude symlinks from the path fixup.
Without it, symlinks in the kernel are broken.

Subject: jump_label: Invoke jump_label_test() via early_initcall()
From: Jason Baron <jbaron(a)akamai.com>
[ Upstream commit 92ee46efeb505ead3ab06d3c5ce695637ed5f152 ]
Fengguang Wu reported that running the rcuperf test during boot can cause
the jump_label_test() to hit a WARN_ON(). The issue is that the core jump
label code relies on kernel_text_address() to detect when it can no longer
update branches that may be contained in __init sections. The
kernel_text_address() in turn assumes that if the system_state variable is
greter than or equal to SYSTEM_RUNNING then __init sections are no longer
valid (since the assumption is that they have been freed). However, when
rcuperf is setup to run in early boot it can call kernel_power_off() which
sets the system_state to SYSTEM_POWER_OFF.
Since rcuperf initialization is invoked via a module_init(), we can make
the dependency of jump_label_test() needing to complete before rcuperf
explicit by calling it via early_initcall().

ip6mr_rules_init() is not called yet, therefore on the error path when

Subject: IB/mlx5: Assign send CQ and recv CQ of UMR QP
From: Majd Dibbiny <majd(a)mellanox.com>
[ Upstream commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 ]
The UMR's QP is created by calling mlx5_ib_create_qp directly, and
therefore the send CQ and the recv CQ on the ibqp weren't assigned.
Assign them right after calling the mlx5_ib_create_qp to assure
that any access to those pointers will work as expected and won't
crash the system as might happen as part of reset flow.

Subject: IB/mlx4: Increase maximal message size under UD QP
From: Mark Bloch <markb(a)mellanox.com>
[ Upstream commit 5f22a1d87c5315a98981ecf93cd8de226cffe6ca ]
Maximal message should be used as a limit to the max message payload allowed,
without the headers. The ConnectX-3 check is done against this value includes
the headers. When the payload is 4K this will cause the NIC to drop packets.
Increase maximal message to 8K as workaround, this shouldn't change current
behaviour because we continue to set the MTU to 4k.
To reproduce;
set MTU to 4296 on the corresponding interface, for example:
ifconfig eth0 mtu 4296 (both server and client)
On server:
ib_send_bw -c UD -d mlx4_0 -s 4096 -n 1000000 -i1 -m 4096
On client:
ib_send_bw -d mlx4_0 -c UD <server_ip> -s 4096 -n 1000000 -i 1 -m 4096

From: Chris Brandt <chris.brandt(a)renesas.com>
[ Upstream commit 2501c1bb054290679baad0ff7f4f07c714251f4c ]
While modifying the driver to use the STOP interrupt, the completion of the
intermediate transfers need to wake the driver back up in order to initiate
the next transfer (restart condition). Otherwise you get never ending
interrupts and only the first transfer sent.

From: Daniel Drake <drake(a)endlessm.com>
[ Upstream commit f2f10b7e722a75c6d75a7f7cd06b0eee3ae20f7c ]
Add support for media keys on the keyboard that comes with the
Asus V221ID and ZN241IC All In One computers.
The keys to support here are WLAN, BRIGHTNESSDOWN and BRIGHTNESSUP.
This device is not visibly branded as Chicony, and the USB Vendor ID
suggests that it is a JESS device. However this seems like the right place
to put it: the usage codes are identical to the currently supported
devices, and this driver already supports the ASUS AIO keyboard AK1D.
