But, This is failing to build the x86 selftests: make: *** No rule to make target 'protection_keys.c', needed by '/home/daveh/linux/tools/testing/selftests/x86/protection_keys_32'. Stop. I think you just forgot to remove the binary from the x86 Makefile. Which reminds me: This removes the 32-bit binary. x86 32-bit binaries exercise different paths than the 64-bit ones, so we like to have both. Although it isn't *essential* it would really be nice to keep the 32-bit binary.
