The quilt patch titled Subject: selftests/mm: fix powerpc ARCH check has been removed from the -mm tree. Its filename was selftests-mm-fix-powerpc-arch-check.patch
This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------ From: Michael Ellerman mpe@ellerman.id.au 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
