Subject: [PATCH 0/2] x86: sp0 fixes

I broke x86_32 and I made an inadvertent change to both bitnesses.
Undo the inadvertent change and fix x86_32.

This isn't as pretty as I hoped.  Sorry.

Andy Lutomirski (2):
  x86: Delay loading sp0 slightly on task switch
  x86: Replace this_cpu_sp0 with current_top_of_stack and fix it on
    x86_32
