      alpha: fix hang caused by the bootmem removal · 5b526090
      Mike Rapoport authored 
      The conversion of alpha to memblock as the early memory manager caused
boot to hang as described at [1].

The issue is caused because for CONFIG_DISCTONTIGMEM=y case,
memblock_add() is called using memory start PFN that had been rounded
down to the nearest 8Mb and it caused memblock to see more memory that
is actually present in the system.

Besides, memblock allocates memory from high addresses while bootmem was
using low memory, which broke the assumption that early allocations are
always accessible by the hardware.

This patch ensures that memblock_add() is using the correct PFN for the
memory start and forces memblock to use bottom-up allocations.

      Pull powerpc fixes from Michael Ellerman:
 "One notable fix for our change to split pt_regs between user/kernel,
  we forgot to update BPF to use the user-visible type which was an ABI
  break for BPF programs.

  A slightly ugly but minimal fix to do_syscall_trace_enter() so that we
  use tracehook_report_syscall_entry() properly. We'll rework the code
  in next to avoid the empty if body.

  Seven commits fixing bugs in the new papr_scm (Storage Class Memory)
  driver. The driver was finally able to be tested on the other
  hypervisor which exposed several bugs. The fixes are all fairly
  minimal at least.

  Fix a crash in our MSI code if an MSI-capable device is plugged into a
  non-MSI capable PHB, only seen on older hardware (MPC8378).

  Fix our legacy serial code to look for "stdout-path" since the device
  trees were updated to use that instead of "linux,stdout-path".

  A change to the COFF zImage code to fix booting old powermacs.

  A couple of minor build fixes.

 "While I hoped things would calm down, the world hasn't joined with me,
  but it's a few things scattered over a wide area. The i915 workarounds
  regression fix is probably the largest, the rest are more usual sized.
  We also get some new AMD PCI IDs.

  There is also a patch in here to MAINTAINERS to added Daniel as an
  official DRM toplevel co-maintainer, he's decided he wants to step up
  and share the glory, and he'll likely process next weeks fixes while
  I'm away on holidays.

  Summary:

  amdgpu:

   - some new PCI IDs

   - fixed firmware image updates

   - power management fixes

   - locking warning fix

  nouveau:

   - framebuffer flushing fix

   - memory leak fix

   - tegra device init regression fix

  vmwgfx:

   - OOM kernel memory fix

   - excess return in function fix

  i915:

   - the biggest fix is a regression fix where workarounds weren't
     getting reapplied after a gpu hang causing further crashing, this
     fixes the workaround application to make it happen again

   - GPU hang fixes for Braswell and some GEN3 GPUs

   - GVT fix for broadwell tiling

  rockchip:

   - revert to fix a regression causing a WARN on shutdown

  mediatek:

   - avoid crash attaching to non-existant bridges"

      fuse: continue to send FUSE_RELEASEDIR when FUSE_OPEN returns ENOSYS · 2e64ff15
      Chad Austin authored 
      When FUSE_OPEN returns ENOSYS, the no_open bit is set on the connection.

Because the FUSE_RELEASE and FUSE_RELEASEDIR paths share code, this
incorrectly caused the FUSE_RELEASEDIR request to be dropped and never sent
to userspace.

Pass an isdir bool to distinguish between FUSE_RELEASE and FUSE_RELEASEDIR
inside of fuse_file_put.

      dm thin: send event about thin-pool state change _after_ making it · f6c36758
      Mike Snitzer authored 
      Sending a DM event before a thin-pool state change is about to happen is
a bug.  It wasn't realized until it became clear that userspace response
to the event raced with the actual state change that the event was
meant to notify about.

Fix this by first updating internal thin-pool state to reflect what the
DM event is being issued about.  This fixes a long-standing racey/buggy
userspace device-mapper-test-suite 'resize_io' test that would get an
event but not find the state it was looking for -- so it would just go
on to hang because no other events caused the test to reevaluate the
thin-pool's state.

      tracing: Fix memory leak of instance function hash filters · 2840f84f
      Steven Rostedt (VMware) authored 
      The following commands will cause a memory leak:

 # cd /sys/kernel/tracing
 # mkdir instances/foo
 # echo schedule > instance/foo/set_ftrace_filter
 # rmdir instances/foo

The reason is that the hashes that hold the filters to set_ftrace_filter and
set_ftrace_notrace are not freed if they contain any data on the instance
and the instance is removed.

Found by kmemleak detector.
