Subject: [PATCH 0/8] selftests: x86: build suite with clang

This series fixes build errors found by clang to allow the x86 suite to
get built with the clang.

Unfortunately, there is one bug [1] in the clang becuase of which
extended asm isn't handled correctly by it and build fails for
sysret_rip.c. Hence even after this series the build of this test would
fail with clang. Should we disable this test for now when clang is used
until the bug is fixed in clang? Not sure. Any opinions?
