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

Log Message:
Add a hint variable (mips_sdcache_forceinv, explicitly initialized to zero)
that tells pmap_zero_page() and pmap_copy_page() to unconditionally invalidate
pages for r5k-class CPUs with secondary cache.

This behavior must be explicitly enabled by setting mips_sdcache_forceinv to 1.

This is the last bit of a patch that has been kicked around since 2000 between
rafal@, tsutsui@, and myself.
