* [IA64-SGI] - New SN hardware support - ptc_fixesJack Steiner2005-08-17
| | | | | | | | | | | | Shub2 provides a much improved mechanism for issuing internode TLB purges. Add code to support the newer mechanism. There is also some debug code (disabled) that is useful for testing. Collect statistics on the number, type & duration of TLB purges. This data will be useful for making future improvements in the algorithms. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | Change the BTE driver so that it works for both shub1 and shub2. Most of the changes are related to the number of cores that use the BTE engine, to the MMR addresses of various shub registers, and to using the correct processor or network physical address.

* [TCP]: Adjust {p,f}ackets_out correctly in tcp_retransmit_skb()Herbert Xu2005-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Well I've only found one potential cause for the assertion failure in tcp_mark_head_lost. First of all, this can only occur if cnt > 1 since tp->packets_out is never zero here. If it did hit zero we'd have much bigger problems. So cnt is equal to fackets_out - reordering. Normally fackets_out is less than packets_out. The only reason I've found that might cause fackets_out to exceed packets_out is if tcp_fragment is called from tcp_retransmit_skb with a TSO skb and the current MSS is greater than the MSS stored in the TSO skb. This might occur as the result of an expiring dst entry. In that case, packets_out may decrease (line 1380-1381 in tcp_output.c). However, fackets_out is unchanged which means that it may in fact exceed packets_out. Previously tcp_retrans_try_collapse was the only place where packets_out can go down and it takes care of this by decrementing fackets_out. So we should make sure that fackets_out is reduced by an appropriate amount here as well. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

| |/ | | | | | | | | | | | | | | | | | | | | sata_sx4 directly references sg->length to calculate total_len in pdc20621_dma_prep(). This is incorrect as dma_map_sg() could have merged multiple sg's into one and, in such case, sg->length doesn't reflect true size of the entry. This patch makes it use sg_dma_len(sg).

| * [SCSI] fix target scanning oops with fc transport classJames.Smart@Emulex.Com2005-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some nasty issues with 2.6.12-rc6. Any request to scan on the lpfc or qla2xxx FC adapters will oops. What is happening is the system is defaulting to non-transport registered targets, which inherit the parent of the scan. On this second scan, performed by the attribute, the parent becomes the shost instead of the rport. The slave functions in the 2 FC adapters use starget_to_rport() routines, which incorrectly map the shost as an rport pointer. Additionally, this pointed out other weaknesses: - If the target structure is torn down outside of the transport, we have no method for it to be regenerated at the proper parent. - We have race conditions on the target being allocated by both the midlayer scan (parent=shost) and by the fc transport (parent=rport).
