Jake Burkholder 92fed30a07 Use the vis block copy/zero functions for pmap_copy_page and pmap_zero_page. ... These are called through function pointers so that different implementations can be provided for cheetah, where the block load instructions may or may not be a win, and so they can be disabled with the machdep.use_vis tunable. In terms of raw bandwidth the integer versions are faster, but not allocating lines in the L2 cache for useless data gives a measurable improvement in user time for the benchmarks I tested (mostly buildworld with -j8). As far as I can tell the instructions used are implemented on everything back to UltraSPARC I, so there should not be a problem with different cpu types.		2003-04-06 17:05:26 +00:00
