Subject: [PATCH 0/2] i387: FP state interface cleanups

This cleans up some of our FP-state mess.  The aim is to expose much
less of the internal interfaces and implementation to various users that
really don't care. 

We shouldn't export our internal 'fpu_owner_task' tracking to modules,
and we shouldn't expose all the low-level FP state save/restore code to
code that simply must never use it anyway.

This passed allmodconfig on x86-32 and -64.

              Linus

Linus Torvalds (2):
  i387: uninline the generic FP helpers that we expose to kernel
    modules
  i387: split up <asm/i387.h> into exported and internal interfaces
