CVS commit: src/sys/arch/arm/arm32

[Steve Woodford <scw%netbsd.org@localhost>]

Module Name:    src
Committed By:   scw
Date:           Tue Apr 26 16:03:08 UTC 2005

Modified Files:
        src/sys/arch/arm/arm32: pmap.c

Log Message:
Since pmap_page_remove() is called from pmap_page_protect(), don't modify
the current pmap's pm_cstate if we have to flush the TLB, as callers of
pmap_page_protect() are not required to invoke pmap_update() afterwards.

Otherwise we can end up with a pm_cstate which is inconsistent with reality
in the TLB, which can lead to future TLB flushes being erroneously skipped.
