2007-10-02	[SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy.	David S. Miller	1	-4/+4
	For the case where the source is not aligned modulo 8 we don't use load-twins to suck the data in and this kills performance since normal loads allocate in the L1 cache (unlike load-twin) and thus big memcpys swipe the entire L1 D-cache. We need to allocate a register window to implement this properly, but that actually simplifies a lot of things as a nice side-effect. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-20	[SPARC64]: Fix some Niagara memcpy() bugs.	David S. Miller	1	-1/+1
	We need to restore the %asi register properly. For the kernel this means get_fs(), for user this means ASI_PNF. Also, NGcopy_to_user.S was including U3memcpy.S instead of NGmemcpy.S, oops :-) Signed-off-by: David S. Miller <davem@davemloft.net>
