The pkey* files can only be built on architectures that support pkeys (pkey-helpers.h #error's otherwise). Adding pkey_util.c as dependency to all $(TEST_GEN_FILES) is therefore a bad idea. Make it a dependency of the pkeys tests only.
Those tests are built in 32/64-bit variants on x86_64 so we need to add an explicit dependency there as well. Signed-off-by: Kevin Brodsky <[email protected]> --- Hi Alexander, Thank you for the bug report, that patch indeed breaks all architectures that don't support pkeys, I should have realised that! This patch should fix it. Andrew, it would make sense to squash this patch into the original ("selftests/mm: Use sys_pkey helpers consistently").
