The 'Array' class is present in more than one python standard library.
In some versions of Python 3, the following error occurs:

Traceback (most recent call last):

    self.buffer = Array(c_char, self.buffer_size, lock=False)
TypeError: abstract class

This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.

Pull siginfo fix from Eric Biederman:
 "During the merge window an issue with si_perf and the siginfo ABI came
  up. The alpha and sparc siginfo structure layout had changed with the
  addition of SIGTRAP TRAP_PERF and the new field si_perf.

  The reason only alpha and sparc were affected is that they are the
  only architectures that use si_trapno.

  Looking deeper it was discovered that si_trapno is used for only a few
  select signals on alpha and sparc, and that none of the other
  _sigfault fields past si_addr are used at all. Which means technically
  no regression on alpha and sparc.

  While the alignment concerns might be dismissed the abuse of si_errno
  by SIGTRAP TRAP_PERF does have the potential to cause regressions in
  existing userspace.

  While we still have time before userspace starts using and depending
  on the new definition siginfo for SIGTRAP TRAP_PERF this set of
  changes cleans up siginfo_t.

   - The si_trapno field is demoted from magic alpha and sparc status
     and made an ordinary union member of the _sigfault member of
     siginfo_t. Without moving it of course.

   - si_perf is replaced with si_perf_data and si_perf_type ending the
     abuse of si_errno.

   - Unnecessary additions to signalfd_siginfo are removed"

Pull module fix from Jessica Yu:
 "When CONFIG_MODULE_UNLOAD=n, module exit sections get sorted into the
  init region of the module in order to satisfy the requirements of
  jump_labels and static_calls.

  Previously, the exit section check was done in module_init_section(),
  but the solution there is not completely arch-indepedent as ARM is a
  special case and supplies its own module_init_section() function.

  Instead of pushing this logic further to the arch-specific code,
  switch to an arch-independent solution to check for module exit
  sections in the core module loader code in layout_sections() instead"

This unfortunately comes up in regular intervals and breaks
GPU reset for the engine in question.

The sched.ready flag controls if an engine can't get working
during hw_init, but should never be set to false during hw_fini.

When amdgpu_ib_ring_tests failed, the reset logic called
amdgpu_device_ip_suspend twice, then deadlock occurred.

[Why]
Active DP dongles return no EDID when dongle
is connected, but VGA display is taken out.
Current driver behavior does not remove the
active display when this happens, and this is
a gap between dongle DTP and dongle behavior.

[How]
For active DP dongles and non-DP scenario,
disconnect sink on detection when no EDID
is read due to timeout.

When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB
entries which need to update in amdgpu_map_buffer() should be multiplied
by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE).

[why]
As per spec, DCN3.x can do 6:1 downscaling and DCN2.x can do 4:1. The
max downscaling limit value for DCN2.x is 250, which means it's
calculated as 1000 / 4 = 250. For DCN3.x this then gives 1000 / 6 = 167.

[how]
Set maximum downscaling limit to 167 for DCN3.x
