selftest/powerpc: Fix false failures for skipped tests

2017-12-14T08:28:17+00:00

[ Upstream commit a6d8a21596df041f36f4c2ccc260c459e3e851f1 ]

Tests under alignment subdirectory are skipped when executed on previous
generation hardware, but harness still marks them as failed.

  test: test_copy_unaligned
  tags: git_version:unknown
  [SKIP] Test skipped on line 26
  skip: test_copy_unaligned
  selftests: copy_unaligned [FAIL]

The MAGIC_SKIP_RETURN_VALUE value assigned to rc variable is retained till
the program exit which causes the test to be marked as failed.

This patch resets the value before returning to the main() routine.
With this patch the test o/p is as follows:

  test: test_copy_unaligned
  tags: git_version:unknown
  [SKIP] Test skipped on line 26
  skip: test_copy_unaligned
  selftests: copy_unaligned [PASS]

selftest/powerpc: Wrong PMC initialized in pmc56_overflow test

2017-01-26T07:24:45+00:00

commit df21d2fa733035e4d414379960f94b2516b41296 upstream.

Test uses PMC2 to count the event. But PMC1 is being initialized.
Patch to fix it.

selftests/powerpc: Fix build break caused by EXPORT_SYMBOL changes

2016-10-06T11:26:42+00:00

The changes to make EXPORT_SYMBOL work in asm, specifically commit
9445aa1a3062 ("ppc: move exports to definitions"), in the kbuild tree,
breaks some of our selftests.

That is because we symlink the kernel code into the selftest, and shim
the required headers, and we are now missing asm/export.h

So create a minimal export.h to keep the tests building once powerpc and
the kbuild trees are merged.

Some of the recent new selftests were missing additions to .gitignore,
add them now.

selftests/powerpc: Add checks for transactional VSXs in signal contexts

2016-10-04T09:33:15+00:00

If a thread receives a signal while transactional the kernel creates a
second context to show the transactional state of the process. This
test loads some known values and waits for a signal and confirms that
the expected values are in the signal context.
