    tools/testing/selftests/vm: fix build error · d8cbe8bf
    Xingxing Su authored
    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));
                                                    ^
