        src/sys/arch/sparc64/sparc64 [netbsd-2-0]: pmap.c

Log Message:
Pull up revision 1.157 (requested by martin in ticket #1013).

do the invalidation of the (virtually-addressed) L1 cache in pmap_remove_all()
(ie. just before we skip the per-page cache invalidations while tearing down
each context) instead of just before we recycle all the contexts in ctx_alloc().
the latter is not good enough since a (physically tagged) L1 cache line is
valid for all contexts, not just the one that was used to instantiate it.
fixes PRs 24126, 25669 and 27730.
