This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  selftests: Remove broken Power9 paste tests and fix compilation issue

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  == SRU Justification ==
  With the Power9 copy_unaligned test removed in bug 1813118,
  we can now move forward and remove the broken paste_unaligned /
  paste_last_unaligned test in selftests/powerpc.

  From the commit message:
      Paste on POWER9 only works to accelerators and not on real memory.
      So these tests just generate a SIGILL.

  Actual test output:
      test: test_paste_unaligned
      tags: git_version:unknown
      !! child died by signal 4
      failure: test_paste_unaligned
      not ok 1..2 selftests: paste_unaligned [FAIL]
      selftests: paste_last_unaligned
      ========================================
      test: test_paste_last_unaligned
      tags: git_version:unknown
      !! child died by signal 4
      failure: test_paste_last_unaligned
      not ok 1..3 selftests: paste_last_unaligned [FAIL]
      selftests: alignment_handler

  (On Power8 these two test will be skipped)

  This patchset will also address the compilation intrduced by b2d35fa
  (selftests: add headers_install to lib.mk) which landed with Bionic
  upstream stable patchset 2019-07-12 (bug 1836426)

  == Fix ==
  * 525661ef (selftests/powerpc: Remove Power9 paste tests)
  * 7e0cf1c9 (selftests/powerpc: Fix Makefiles for headers_install change)

  These has been applied in Disco.

  As Cosmic will reach EOL soon, and we don't have alignment tests in
  Xenial, we only need this for Bionic.

  == Test ==
  Patch tested on a P9 node "baltar", test build OK and these two tests
  were removed as expected.

  == Regression Potential ==
  Low.
  Code change limited to testing tools for Power9 and just removing
  broken tests, fix build error.
