The pointer fbi is dereferenced with par = fbi->par before there is a
null check on fbi, hence there is a potential null pointer dereference
on a null par. Fix this by moving the dereference after the null
pointer check.

fbcon: Initialize ops->info early
During console takeover, which happens for all DRM/KMS setups using the
fbdev helpers, fbcon_startup() is called before fbcon_init() and as a
result con2fb_acquire_newinfo() will not be called (info->fbcon_par was
set to non-NULL in fbcon_startup()) to assign ops->info.
This causes the cursor_timer_handler() to unreference a NULL pointer.
Avoid this by unconditionally assigning ops->info during fbcon_startup()
so that it will be available early, but keep the additional assignment
in con2fb_acquire_newinfo() to support console remapping at runtime.

Dan's static analysis says:

Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22,
which may lead to an out of bounds read when parsing vmode commandline
options.
The bug was introduced in v2.4.5.6, when 2 new modes were added to

Pull watchddog clean-up and fixes from Thomas Gleixner:
"The watchdog (hard/softlockup detector) code is pretty much broken in
its current state. The patch series addresses this by removing all
duct tape and refactoring it into a workable state.
The reasons why I ask for inclusion that late in the cycle are:
1) The code causes lockdep splats vs. hotplug locking which get
reported over and over. Unfortunately there is no easy fix.
2) The risk of breakage is minimal because it's already broken
3) As 4.14 is a long term stable kernel, I prefer to have working
watchdog code in that and the lockdep issues resolved. I wouldn't
ask you to pull if 4.14 wouldn't be a LTS kernel or if the
solution would be easy to backport.
4) The series was around before the merge window opened, but then got
delayed due to the UP failure caused by the for_each_cpu()
surprise which we discussed recently.
Changes vs. V1:
- Addressed your review points
- Addressed the warning in the powerpc code which was discovered late
- Changed two function names which made sense up to a certain point
in the series. Now they match what they do in the end.
- Fixed a 'unused variable' warning, which got not detected by the
intel robot. I triggered it when trying all possible related config
combinations manually. Randconfig testing seems not random enough.

We trap and emulate some instructions (e.g, mrs, deprecated instructions)

by that time (with populate_rootfs, which is a rootfs_initcall()). This

Memory hot unplug on PowerNV radix hosts is broken. Our memory block
size is 256MB but since we map the linear region with very large

A hot unplug of one 256MB memory block results in 768MB of memory

Fix this by increasing our memory block size to 1GB on PowerNV radix

dm raid: fix incorrect status output at the end of a "recover" process
There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action. They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.
This commit fixes a condition that is reported incorrectly. When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array. When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
curr_resync_completed = <max dev size> (but not MaxSector)
and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync. This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.
This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process. Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().
Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

KVM: add X86_LOCAL_APIC dependency
The rework of the posted interrupt handling broke building without

That configuration is probably not particularly useful anyway, so
we can avoid the randconfig failures by adding a Kconfig dependency.

ovl: fix regression caused by exclusive upper/work dir protection
Enforcing exclusive ownership on upper/work dirs caused a docker
regression: https://github.com/moby/moby/issues/34672.
Euan spotted the regression and pointed to the offending commit.
Vivek has brought the regression to my attention and provided this
reproducer:
Terminal 1:
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
Terminal 2:
unshare -m
Terminal 1:
umount merged
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
mount: /root/overlay-testing/merged: none already mounted or mount point
busy
To fix the regression, I replaced the error with an alarming warning.
With index feature enabled, mount does fail, but logs a suggestion to
override exclusive dir protection by disabling index.
Note that index=off mount does take the inuse locks, so a concurrent
index=off will issue the warning and a concurrent index=on mount will fail.
Documentation was updated to reflect this change.

"Our first batch of fixes this release cycle, unfortunately a bit

- Some pinctril dts/dtsi changes for stm32 due to a new driver being
merged during the merge window, and this aligns the DT contents
between the old format and the new. This could arguably be moved to
the next merge window but it also seemed relatively harmless to
include now.
- Amlogic/meson had driver changes merged that required devicetree
changes to avoid functional/performance regressions. I've already
asked them to be more careful about this going forward, and making
sure drivers are compatible with older DTs when they make these
kind of changes. The platform is actively being upstreamed so
there's a few things in flight, we've seen this happen before and
sometimes it's hard to catch in time.
