Subject: tools/testing/selftests/vm: fix build error
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));
^
