kernel/tools/testing/selftests/powerpc/mm, branch linux-4.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.1.y2015-04-15T23:35:19Zmm, selftests: test return value of munmap for MAP_HUGETLB memory2015-04-15T23:35:19ZDavid Rientjesrientjes@google.com2015-04-15T23:14:29Zurn:sha1:215ba78115f82ad5f8faedac98cc42e572733b8a
When MAP_HUGETLB memory is unmapped, the length must be hugepage aligned,
otherwise it fails with -EINVAL.
All tests currently behave correctly, but it's better to explcitly test
the return value for completeness and document the requirement, especially
if users copy map_hugetlb.c as a sample implementation.

selftests: Add install support for the powerpc tests2015-03-19T18:38:51ZMichael Ellermanmpe@ellerman.id.au2015-03-11T04:06:01Zurn:sha1:6faeeea44b84ce24fc6c1f1beb07ee5de9885dc8
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.

This patch includes all of the powerpc test binaries into the .gitignore
file listing in their respective directories. This will make sure that
git ignores all of these test binaries when displaying status.
