Subject: Xen 32-bit PV regression
Date: Thu, 03 Apr 2014 23:23:07 -0400 [thread overview]
Message-ID: <533E259B.4030507@oracle.com> (raw)
Steven,
Looks like commit 198d208df (x86: Keep thread_info on thread stack in
x86_32) broke Xen's 32-bit PV guests.
I poked a little at it and it seems that at least the ifdef in
xen_cpu_up() needs to be adjusted to set up kernel_stack --- that allows
CPUs to get going. This is not enough though (not particularly
surprisingly) and we die a little later with #GPF in xen_iret.
