[PATCH] sparc64: Use arch_validate_flags() to validate ADI flag

When userspace calls mprotect() to enable ADI on an address range, do_mprotect_pkey() calls arch_validate_prot() to validate new protection flags. arch_validate_prot() for sparc looks at the first VMA associated with address range to verify if ADI can indeed be enabled on this address range. This
