Michael Ellerman cd4a6f3ab4 selftests/powerpc: Skip the subpage_prot tests if the syscall is unavailable ... The subpage_prot syscall is only functional when the system is using the Hash MMU. Since commit 5b2b807147 ("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 <mpe@ellerman.id.au>		2018-03-02 11:37:04 +11:00
