Subject: selftests: arm64: list of test failures

selftests: arm64 below list of test cases fails on Linux next and
Linux mainline builds with clang-16 and gcc-12 kernel booted on
recently configured tuxrun qemu-arm64 (v7.2) enabled with MTE=on.

Am I missing anything on test configs / environment ?

List of selftests: arm64 test failures,
 - not ok 38 selftests: arm64: check_buffer_fill # exit=1
 - not ok 39 selftests: arm64: check_child_memory # exit=1
