[ Upstream commit d8cbe8bfa7df3c680ddfd5e1eee3a5c86d8dc764 ]
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)); ^
