selftests: Print the test we're running to /dev/kmsg

2018-05-30T05:49:10Z

[ Upstream commit 88893cf787d3062c631cc20b875068eb11756e03 ] Some tests cause the kernel to print things to the kernel log buffer (ie. printk), in particular oops and warnings etc. However when running all the tests in succession it's not always obvious which test(s) caused the kernel to print something. We can narrow it down by printing which test directory we're running in to /dev/kmsg, if it's writable.

selftests/powerpc: Skip the subpage_prot tests if the syscall is unavailable

2018-05-30T05:49:03Z

[ Upstream commit cd4a6f3ab4d80cb919d15897eb3cbc85c2009d4b ] The subpage_prot syscall is only functional when the system is using the Hash MMU. Since commit 5b2b80714796 ("powerpc/mm: Invalidate subpage_prot() system call on radix platforms") it returns ENOENT when the Radix MMU is active. Currently this just makes the test fail. Additionally the syscall is not available if the kernel is built with 4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns ENOSYS because the syscall is missing entirely. So check explicitly for ENOENT and ENOSYS and skip if we see either of those. Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman
