David S. Miller	cf5adce117	[SPARC64]: Niagara-2 optimized copies. The bzero/memset implementation stays the same as Niagara-1. Signed-off-by: David S. Miller <davem@davemloft.net>	2007-08-16 01:47:25 -07:00
David S. Miller	24d559cac4	[SPARC64]: store-init needs trailing membar. 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 <davem@davemloft.net>	2007-03-19 13:27:33 -07:00
David S. Miller	6241e5cc6a	[SPARC64]: Fix branch signedness bug in all code patching. The bug that hit SUN4V TLB patching exists elsewhere. Make sure we cure all such cases. Signed-off-by: David S. Miller <davem@davemloft.net>	2006-03-20 01:12:29 -08:00
David S. Miller	8591e30272	[SPARC64]: Niagara copy/clear page. 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 <davem@davemloft.net>	2006-03-20 01:11:54 -08:00
