CVS commit: src/sys/arch/x86/x86

Module Name:    src
Committed By:   cherry
Date:           Wed Feb  1 18:55:33 UTC 2012

Modified Files:
        src/sys/arch/x86/x86: pmap.c

Log Message:
amd64/Xen doesn't require special treatment for pmap_is_curpmap(),
since cpu_load_pmap() ensures that the linear map is in place for the
kernel. This emulates normal shared kernel mappings, except for the
recursive mapping of the PDP_BASE, which will point to the per-cpu
pdir, which will be a copy of the pmap_kernel()->pm_pdir; instead of
the user pmap->pm_pdir.
