CVS commit: src/sys/arch/hppa

[Nick Hudson <skrll%netbsd.org@localhost>]

Module Name:    src
Committed By:   skrll
Date:           Fri Mar 19 07:29:44 UTC 2010

Modified Files:
        src/sys/arch/hppa/hppa: pmap.c
        src/sys/arch/hppa/include: pmap.h

Log Message:
Not all PA CPUs have the U-bit (uncacheable) for non-IO memory.  In fact
most don't.  Deal with non-equivalent aliases by removing and flushing the
managed mappings, and flushing the unmanaged mappings.

When flushing caches/TLB flush the cache before purging the TLB just in
case the flush enters the mapping into the TLB.
