Subject: [PATCH 0/2] x86: sp0 fixes
Date: Fri,  6 Mar 2015 17:50:17 -0800	[thread overview]
Message-ID: <cover.1425692936.git.luto@amacapital.net> (raw)

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
