Subject: selftests/mm: fix powerpc ARCH check
Date: Mon, 6 May 2024 21:58:25 +1000
In commit 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM")
the logic to detect the machine architecture in the Makefile was changed
to use ARCH, and only fallback to uname -m if ARCH is unset. However the
tests of ARCH were not updated to account for the fact that ARCH is
"powerpc" for powerpc builds, not "ppc64".
Fix it by changing the checks to look for "powerpc", and change the
uname -m logic to convert "ppc64.*" into "powerpc".
With that fixed the following tests now build for powerpc again:
* protection_keys
* va_high_addr_switch
* virtual_address_range
* write_to_hugetlbfs
