Subject: [PATCH 0/3] OpenRISC Switch and Clone cleanups

These are a few patches that came after auditing the OpenRISC switch code
recently following the discussion with Rob and Arnd and the clone and clone3
wrappers [0].

I noticed a few places where OpenRISC could shave a few instructions and also
that we need a ABI wrapper for clone3.

Stafford Horne (3):
  openrisc: Cleanup switch code and comments
  openrisc: Use delay slot for clone and fork wrappers
  openrisc: Add clone3 ABI wrapper
