selftests, x86: Rework x86 target architecture detection

2015-05-13T02:02:40+00:00

We currently fail to build on a non-multilib x86_64 target.  We
print a helpful error, but it's nicer to allow the build to succeed.
Fix it and improve cross-compilation support by detecting
architecture support directly and building only the relevant tests.

selftests, x86: Remove useless run_tests rule

2015-05-13T02:02:22+00:00

Now that selftests/x86 uses the kselftest infrastructure, the
run_x86_tests.sh mechanism is just in the way.

selftests/x86: install tests

2015-05-13T02:00:37+00:00

Include lib.mk and set TEST_PROGS where appropriate.

selftest/x86: have no dependency on all when cross building

2015-05-13T02:00:15+00:00

If the CROSS_COMPILE is set remove all's dependency on all_32 and all_64.

selftest/x86: build both bitnesses

2015-05-13T01:59:55+00:00

Using uname with the processor flag option in some cases can yield 'unknown'
so lets use the machine flag option as it is deterministic. Add a dependency
for all_32 when building on a x86 64 bit host so that both bitnesses are
built in this case.

selftests/powerpc: Fix the pmu install rule

2015-05-01T03:00:26+00:00

My patch to add install support for the powerpc selftests had a typo,
leading to the three tests in the pmu directory itself not being
installed.

Revert "powerpc/tm: Abort syscalls in active transactions"

2015-04-30T05:24:58+00:00

This reverts commit feba40362b11341bee6d8ed58d54b896abbd9f84.

Although the principle of this change is good, the implementation has a
few issues.

Firstly we can sometimes fail to abort a syscall because r12 may have
been clobbered by C code if we went down the virtual CPU accounting
path, or if syscall tracing was enabled.

Secondly we have decided that it is safer to abort the syscall even
earlier in the syscall entry path, so that we avoid the syscall tracing
path when we are transactional.

So that we have time to thoroughly test those changes we have decided to
revert this for this merge window and will merge the fixed version in
the next window.

NB. Rather than reverting the selftest we just drop tm-syscall from
TEST_PROGS so that it's not run by default.
