Subject: [PATCH 0/3] x86/entry/64: Fixes for syscall rework

I broke iopl(2) with my syscall rework.  Fix it up.  While debugging
it, I found a bug in my IRQ state handling.  Fix that, too.

Andy Lutomirski (3):
  x86/entry/64: Fix an IRQ state error on ptregs-using syscalls
  x86/entry/64: Fix fast-path syscall return register state
  x86/syscalls/64: Mark sys_iopl as using ptregs
