drm/client: Restrict the plane_state scope
The drm_client_modeset_commit_atomic function uses two times the
plane_state variable in inner blocks of code, but the variable has a scope
global to this function.

This will lead to inadvertent devs to reuse the variable in the second
block with the value left by the first, without any warning from the
compiler since value would have been initialized.

Fix this by moving the variable declaration to the proper scope.

Serge Semin 8a08e50cee drm: Permit video-buffers writecombine mapping for MIPS
Since commit 4b050ba7a6 ("MIPS: pgtable.h: Implement the
pgprot_writecombine function for MIPS") and commit c4687b15a8 ("MIPS: Fix
definition of pgprot_writecombine()") write-combine vma mapping is
available to be used by kernel subsystems for MIPS. In particular the
uncached accelerated attribute is requested to be set by ioremap_wc()
method and by generic PCI memory pages/ranges mapping methods. The same
is done by the drm_io_prot()/ttm_io_prot() functions in case if
write-combine flag is set for vma's passed for mapping. But for some
reason the pgprot_writecombine() method calling is ifdefed to be a
platform-specific with MIPS system being marked as lacking of one. At the
very least it doesn't reflect the current MIPS platform implementation.
So in order to improve the DRM subsystem performance on MIPS with UCA
mapping enabled, we need to have pgprot_writecombine() called for buffers,
which need store operations being combined. In case if particular MIPS
chip doesn't support the UCA attribute, the mapping will fall back to
noncached.

Boris Brezillon 7786fd1087 drm/panfrost: Expose performance counters through unstable ioctls
Expose performance counters through 2 driver specific ioctls: one to
enable/disable the perfcnt block, and one to dump the counter values.

There are discussions to expose global performance monitors (those
counters that can't be retrieved on a per-job basis) in a consistent
way, but this is likely to take time to settle on something that works
for various HW/users.
The ioctls are marked unstable so we can get rid of them when the time
comes. We initally went for a debugfs-based interface, but this was
making the transition to per-FD address space more complicated (we need
to specify the namespace the GPU has to use when dumping the perf
counters), hence the decision to switch back to driver specific ioctls
which are passed the FD they operate on and thus will have a dedicated
address space attached to them.

Other than that, the implementation is pretty simple: it basically dumps
all counters and copy the values to a userspace buffer. The parsing is
left to userspace which has to know the specific layout that's used
by the GPU (layout differs on a per-revision basis).

Boris Brezillon 92f0ad0b1d drm/panfrost: Add a module parameter to expose unstable ioctls
We plan to expose performance counters through 2 driver specific
ioctls until there's a solution to expose them in a generic way.
In order to be able to deprecate those ioctls when this new
infrastructure is in place we add an unsafe module parameter that
will keep those ioctls hidden unless it's set to true (which also
has the effect of tainting the kernel).

All unstable ioctl handlers should use panfrost_unstable_ioctl_check()
to check whether they're supposed to handle the request or reject it
with ENOSYS.

 "The accumulated fixes from this and last week:

   - Fix vmalloc TLB flush and map range calculations which lead to
     stale TLBs, spurious faults and other hard to diagnose issues.

   - Use fault_in_pages_writable() for prefaulting the user stack in the
     FPU code as it's less fragile than the current solution

   - Use the PF_KTHREAD flag when checking for a kernel thread instead
     of current->mm as the latter can give the wrong answer due to
     use_mm()

   - Compute the vmemmap size correctly for KASLR and 5-Level paging.
     Otherwise this can end up with a way too small vmemmap area.

   - Make KASAN and 5-level paging work again by making sure that all
     invalid bits are masked out when computing the P4D offset. This
     worked before but got broken recently when the LDT remap area was
     moved.

   - Prevent a NULL pointer dereference in the resource control code
     which can be triggered with certain mount options when the
     requested resource is not available.

   - Enforce ordering of microcode loading vs. perf initialization on
     secondary CPUs. Otherwise perf tries to access a non-existing MSR
     as the boot CPU marked it as available.

   - Don't stop the resource control group walk early otherwise the
     control bitmaps are not updated correctly and become inconsistent.

   - Unbreak kgdb by returning 0 on success from
     kgdb_arch_set_breakpoint() instead of an error code.

   - Add more Icelake CPU model defines so depending changes can be
     queued in other trees"

Douglas Anderson 527e4ca3b6 drm/rockchip: Base adjustments of the mode based on prev adjustments
In vop_crtc_mode_fixup() we fixup the mode to show what we actually
will be able to achieve.  However we should base our adjustments on
any previous adjustments that were made.

As an example, the dw_hdmi driver may wish to make some small
adjustments to clock rates in its atomic_check() function.  If it
does, it will update the adjusted_mode.  We shouldn't throw away those
adjustments.

NOTE: the version of the dw_hdmi driver upstream doesn't _actually_
make such adjustments, but downstream in Chrome OS it does.  It is
plausible that one day we'll figure out how to cleanly make that
happen in an upstream-friendly way, so we should prepare by using the
right mode.

Douglas Anderson 99b9683f21 drm/rockchip: Properly adjust to a true clock in adjusted_mode
When fixing up the clock in vop_crtc_mode_fixup() we're not doing it
quite correctly.  Specifically if we've got the true clock 266666667 Hz,
we'll perform this calculation:
   266666667 / 1000 => 266666

Later when we try to set the clock we'll do clk_set_rate(266666 *
1000).  The common clock framework won't actually pick the proper clock
in this case since it always wants clocks <= the specified one.

Let's solve this by using DIV_ROUND_UP.

 Nothing major, just some small gadget fixes, usb-serial new device ids,
 a few new quirks, and some small fixes for some regressions that have
 been found after the big 5.2-rc1 merge.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds fa1827d773 powerpc fixes for 5.2 #4
One fix for a regression introduced by our 32-bit KASAN support, which broke
 booting on machines with "bootx" early debugging enabled.
 
 A fix for a bug which broke kexec on 32-bit, introduced by changes to the 32-bit
 STRICT_KERNEL_RWX support in v5.1.
 
 Finally two fixes going to stable for our THP split/collapse handling,
 discovered by Nick. The first fixes random crashes and/or corruption in guests
 under sufficient load.
 
 Thanks to:
   Nicholas Piggin, Christophe Leroy, Aaro Koskinen, Mathieu Malaterre.

Borislav Petkov 78f4e932f7 x86/microcode, cpuhotplug: Add a microcode loader CPU hotplug callback
Adric Blake reported the following warning during suspend-resume:

  Enabling non-boot CPUs ...
  x86: Booting SMP configuration:
  smpboot: Booting Node 0 Processor 1 APIC 0x2
  unchecked MSR access error: WRMSR to 0x10f (tried to write 0x0000000000000000) \

  CPU1 is up

The MSR in question is MSR_TFA_RTM_FORCE_ABORT and that MSR is emulated
by microcode. The log above shows that the microcode loader callback
happens after the PMU restoration, leading to the conjecture that
because the microcode hasn't been updated yet, that MSR is not present
yet, leading to the #GP.

Add a microcode loader-specific hotplug vector which comes before
the PERF vectors and thus executes earlier and makes sure the MSR is
present.

Pull cgroup fixes from Tejun Heo:
 "This has an unusually high density of tricky fixes:

   - task_get_css() could deadlock when it races against a dying cgroup.

   - cgroup.procs didn't list thread group leaders with live threads.

     This could mislead readers to think that a cgroup is empty when
     it's not. Fixed by making PROCS iterator include dead tasks. I made
     a couple mistakes making this change and this pull request contains
     a couple follow-up patches.

   - When cpusets run out of online cpus, it updates cpusmasks of member
     tasks in bizarre ways. Joel improved the behavior significantly"

Casey Schaufler 6e7739fc93 Smack: Restore the smackfsdef mount option and add missing prefixes
The 5.1 mount system rework changed the smackfsdef mount option to
smackfsdefault.  This fixes the regression by making smackfsdef treated
the same way as smackfsdefault.

Also fix the smack_param_specs[] to have "smack" prefixes on all the
names.  This isn't visible to a user unless they either:

 (a) Try to mount a filesystem that's converted to the internal mount API
     and that implements the ->parse_monolithic() context operation - and
     only then if they call security_fs_context_parse_param() rather than
     security_sb_eat_lsm_opts().

     There are no examples of this upstream yet, but nfs will probably want
     to do this for nfs2 or nfs3.

 (b) Use fsconfig() to configure the filesystem - in which case
     security_fs_context_parse_param() will be called.

This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix
on the options, but smack_fs_context_parse_param() does not.

Fixes: c3300aaf95 ("smack: get rid of match_token()")
Fixes: 2febd254ad ("smack: Implement filesystem context security hooks")

Josh Poimboeuf 9f255b632b module: Fix livepatch/ftrace module text permissions race

The above panic occurs when loading two modules at the same time with
ftrace enabled, where at least one of the modules is a livepatch module:

CPU0					CPU1
klp_enable_patch()
  klp_init_object_loaded()
    module_disable_ro()
    					ftrace_module_enable()
					  ftrace_arch_code_modify_post_process()
				    	    set_all_modules_text_ro()
      klp_write_object_relocations()
        apply_relocate_add()
	  *patches read-only code* - BOOM

A similar race exists when toggling ftrace while loading a livepatch
module.

Fix it by ensuring that the livepatch and ftrace code patching
operations -- and their respective permissions changes -- are protected
by the text_mutex.

Pull arm64 fixes from Will Deacon:
 "Here are some arm64 fixes for -rc5.

  The only non-trivial change (in terms of the diffstat) is fixing our
  SVE ptrace API for big-endian machines, but the majority of this is
  actually the addition of much-needed comments and updates to the
  documentation to try to avoid this mess biting us again in future.

  There are still a couple of small things on the horizon, but nothing
  major at this point.

  Summary:

   - Fix broken SVE ptrace API when running in a big-endian configuration

   - Fix performance regression due to off-by-one in TLBI range checking

   - Fix build regression when using Clang"

 Other than that, there are a few regression fixes for the recent
