Subject[PATCH 0/3] x86/entry: A compat syscall bugfix and some test stuff
Date
The compat syscall argument fixup error path is wrong.  Fix it.

This also adds some sanity checks to the kernel that catch the bug
when running selftests.

Andy Lutomirski (3):
entry: Check that syscall entries and syscall exits match
x86/entry: Fix entry/exit mismatch on failed fast 32-bit syscalls
selftests/x86: Add a missing .note.GNU-stack section to thunks_32.S
