[PATCH 0/3] x86: Clean up SYSRET/SYSEXIT validation

[Brian Gerst]

This series cleans up the tests for using the SYSRET or SYSEXIT
instructions on exit from a syscall, moving some code from assembly to C
and merging native and compat tests.

Brian Gerst (3):
  x86-64: Move SYSRET validation code to C
  x86-32: Remove SEP test for SYSEXIT
  x86: Clean up do_fast_syscall_32() tests
