CVS commit: src/sys/arch/i386/i386

[Jean-Yves Migeon <jym%netbsd.org@localhost>]

Module Name:    src
Committed By:   jym
Date:           Wed Jul 28 17:05:51 UTC 2010

Modified Files:
        src/sys/arch/i386/i386: mptramp.S

Log Message:
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...
