CVS commit: [matt-nb5-mips64] src/sys/arch/mips

[Matt Thomas <matt%netbsd.org@localhost>]

Module Name:    src
Committed By:   matt
Date:           Thu Feb 25 05:53:23 UTC 2010

Modified Files:
        src/sys/arch/mips/include [matt-nb5-mips64]: pmap.h
        src/sys/arch/mips/mips [matt-nb5-mips64]: pmap.c pmap_tlb.c

Log Message:
Make the UP and MP ASID allocation algorithm common.  Significantly improve
the algorithm.  Now when we exhaust the ASIDs, interrogate the TLB for active
ASIDS and release all the other for future allocations.  This leaves the
TLB entries with ASIDs valid avoiding the need to re-incur TLB misses for
them.
