CVS commit: src/sys/arch/i386/i386
Module Name: src
Committed By: jym
Date: Wed Jul 28 17:05:51 UTC 2010
Enable the NX bit feature early in i386 MP trampoline code (do not rely on
cpu_init_msrs() to do it). Having NX bit set on a page will raise a #GP
on fetch if NXE is not enabled, which can happen early when structures
(like idlelwp) are allocated with just rw- rights.
NX is enabled with PAE (if host supports it).
Exact same issue as for amd64, some weeks ago. Same player, shoot again...
