selftests/powerpc: Test the THP bug we fixed in the previous commit Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

selftests/powerpc: Add a test for PROT_SAO PROT_SAO is a powerpc-specific flag to mmap(), and we rely on arch specific logic to allow it to be passed to mmap(). Add a small test to ensure mmap() accepts PROT_SAO. We don't have a good way to test that it actually causes the mapping to be created with the right flags, so for now we just touch the mapping so it's faulted in. In future we might be able to do something better. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

selftests: Add install support for the powerpc tests The bulk of the selftests are actually below the powerpc sub directory. This adds support for installing them, when on a powerpc machine, or if ARCH and CROSS_COMPILE are set appropriately. This is a little more complicated because of the sub directory structure under powerpc, but much of the common logic in lib.mk is still used. The net effect of the patch is still a reduction in code.
