sparc,sparc64: unify lib/

2008-12-04T17:17:19+00:00

o Renamed files in sparc64 to _64.S when identical to sparc32 files. o iomap.c were equal for sparc32 and sparc64 o adjusted sparc/Makefile now we have only one lib/ Signed-off-by: Sam Ravnborg Signed-off-by: David S. Miller

[SPARC64]: Niagara-2 optimized copies.

The bzero/memset implementation stays the same as Niagara-1. Signed-off-by: David S. Miller

[SPARC64]: store-init needs trailing membar.

2007-03-19T20:27:33+00:00

The manual says that it is required and we actually have crash reports where loads see stale data due to not having membars here. In one case the networking does: memset(skb, 0, offsetof(struct sk_buff, truesize)); and then some code later checks skb->nohdr for zero, but it's still the value that was there before the memset(). Note that arch/sparc64/lib/xor.S already got this right. Signed-off-by: David S. Miller

[SPARC64]: Fix branch signedness bug in all code patching.

2006-03-20T09:12:29+00:00

The bug that hit SUN4V TLB patching exists elsewhere. Make sure we cure all such cases. Signed-off-by: David S. Miller

[SPARC64]: Niagara copy/clear page.

2006-03-20T09:11:54+00:00

Happily we have no D-cache aliasing issues on these chips, so the implementation is very straightforward. Add a stub in bootup which will be where the patching calls will be made for niagara/sun4v/hypervisor. Signed-off-by: David S. Miller
