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
