Only x86 and PowerPC implement the pkey-xxx.h, and an error was reported when compiling protection_keys.c. Add a Arch judgment to compile "protection_keys" in the Makefile. If other arch implement this, add the arch name to the Makefile. eg: ifneq (,$(findstring $(ARCH),powerpc mips ... )) Following build errors: pkey-helpers.h:93:2: error: #error Architecture not supported #error Architecture not supported pkey-helpers.h:96:20: error: `PKEY_DISABLE_ACCESS' undeclared #define PKEY_MASK (PKEY_DISABLE_ACCESS | PKEY_DISABLE_WRITE) ^ protection_keys.c:218:45: error: `PKEY_DISABLE_WRITE' undeclared pkey_assert(flags & (PKEY_DISABLE_ACCESS | PKEY_DISABLE_WRITE)); ^ Signed-off-by: Xingxing Su <suxingxing@loongson.cn> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Shuah Khan <shuah@kernel.org> Cc: Sandipan Das <sandipan@linux.ibm.com> Cc: John Hubbard <jhubbard@nvidia.com> Cc: Dave Hansen <dave.hansen@intel.com> Cc: "Kirill A.
