[PATCH v2] selftests: mm: add s390 to ARCH check

due to the ARCH variable already being set and the arch folder name being s390. Add "s390" to the filtered list to cover this case and have the 3 files included in the build. Fixes: 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM") Cc: sta...@kernel.org Cc: Mark Br

[PATCH] selftests: mm: add s390 to ARCH check

When compiling with ARCH already set, the s390x ARCH is actually s390. Add s390 to the ARCH check list, so we can properly build selftests for s390. Signed-off-by: Nico Pache --- tools/testing/selftests/mm/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools

failures and improving the overall robustness of the test suite. Nico Pache (3): selftests/mm: Dont fail testsuite due to a lack of hugepages selftests/mm: Skip uffd hugetlb tests with insufficient hugepages selftests/mm: Skip the hugetlb-madvise tests on unmet hugepage requirements

Now that run_vmtests.sh does not guarantee that the correct hugepage count is available, skip the hugetlb-madvise test if the requirements are not met rather than failing. Signed-off-by: Nico Pache --- tools/testing/selftests/mm/hugetlb-madvise.c | 3 ++- 1 file changed, 2 insertions(+), 1

Hi Andrew, No, I think it's always been broken-- I don't think the test was written with 512M huge page sizes in mind. -- Nico On Sat, Jan 20, 2024 at 9:39 PM Andrew Morton wrote: > > On Fri, 19 Jan 2024 06:14:29 -0700 Nico Pache wrote: > > > On systems with 64k pag
