Subject: [RFC PATCH 0/2] x86/fpu: Remove xstate_fault()

From: Borislav Petkov <bp@...e.de>

Hi,

so that xstate_fault() thing did cause trouble in the past, see

  06c8173eb92b ("x86/fpu/xsaves: Fix improper uses of __ex_table")

So lemme kill it.

I had an earlier version of that patch, here's an updated one and split
into two for better digestion.

The guest boots fine so far, I need to run it on the rest of the hw to
check everything's fine.

Borislav Petkov (2):
  x86/fpu: Add an XSTATE_OP macro
  x86/fpu: Get rid of xstate_fault()
