CVS: cvs.openbsd.org: src

From: Kurt Miller (kurtcvs.openbsd.org)
Date: Thu Dec 18 2008 - 08:17:28 CST


CVSROOT: /cvs
Module name: src
Changes by: kurtcvs.openbsd.org 2008/12/18 07:17:28

Modified files:
        sys/arch/i386/i386: machdep.c pmap.c
        sys/arch/i386/include: pmap.h

Log message:
Don't set the global bit PG_G for kernel pmap low memory mappings. Use a
new function pmap_prealloc_lowmem_ptp() to setup kernel pmap ptp 0 without
the PG_G bit set. This fixes the remaining reaper -> pmap_page_remove
panics. With much diagnostic help from Art and Theo.
