linux-next: manual merge of the tip tree with the kselftest-fixes tree

From: Stephen Rothwell

Hi all,

Today's linux-next merge of the tip tree got a conflict in
tools/testing/selftests/x86/Makefile between commit e9886ace222e
("selftests, x86: Rework x86 target architecture detection") from the
kselftest-fixes tree and commit e22438f8e997 ("x86, selftests: Add a
test for the "sysret_ss_attrs" bug") from the tip tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
