2005-08-26[IA64] altix: Abstract irq_affinity at the sn pci providerMark Maule
Altix patch to abstract irq_affinity down to the pci provider level since different SGI hardware implements this in different ways. Signed-off-by: Mark Maule <maule@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-08-24[IA64] SGI SN remove redundant partition SAL callRuss Anderson
Clean up of SGI SN partitioning related code. The SN_SAL_GET_SN_INFO SAL call returns the partition ID, making the SN_SAL_SYSCTL_PARTITION_GET SAL call redundant. Remove sn_partid and use sn_partition_id. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-08-24[IA64] - SGI SN hwperf enhancements -Mark Goodwin
Update the SN pci device info to use the nearest node function to allocate driver memory on the nearest node (rather than defaulting to node 0). Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-08-24[IA64] - SGI SN hwperf enhancements -Mark Goodwin
Add a new exported function for determining the nearest node with CPUs for I/O nodes and fix a bug where the hwperf dynamic misc device was being registered before misc_init(). Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-08-17[IA64-SGI] - New SN hardware support - ptc_fixesJack Steiner
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.

2005-08-17[IA64-SGI] - New SN hardware support - bte_fixesJack Steiner
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.

2005-08-17[IA64-SGI] - New SN hardware support - boot_init_shub2Jack Steiner
Update the addresses of the pio_write_status_addr so that they are correct for newer processors. Shub2 did not number the threads in the order that I had expected. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-08-17[IA64-SGI] - New SN hardware support - use_alias_spaceJack Steiner
Use local SHUB alias space when referencing MMRs that are known to be node local. There is a slight performance benefit & code simplification. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-08-17[IA64-SGI] - New SN hardware support - addr_macrosJack Steiner
Update the SN address macros so that they work on both shub1 and shub2. Most of the code to support shub2 was added last year but this patch fixes a few bugs and adds macros to help generate both processor-specific physical addresses & numalink physical addresses. More cleanup & optimization will be done later. Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-08-10[TCP]: Adjust {p,f}ackets_out correctly in tcp_retransmit_skb()Herbert Xu
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>

2005-08-10[PATCH] remove name length check in a workqueueJames Bottomley
We have a chek in there to make sure that the name won't overflow task_struct.comm[], but it's triggering for scsi with lots of HBAs, only scsi is using single-threaded workqueues which don't append the "/%d" anyway. All too hard. Just kill the BUG_ON.

2005-08-10[PATCH] ns558 list handling fixAlexander Nyberg
Need to use list_for_entry_safe(), as we're removing items during the traversal. list_for_each_entry() uses the first ptr also as an iterator, if you kfree() it slab takes it, might poison it and then you try to use it to iterate to the next object in list.

2005-08-10[PATCH] sata: fix sata_sx4 dma_prep to not use sg->lengthTejun Heo
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).

2005-08-10[ARM] Control v6 'global' bit via Linux PTE entriesRussell King
Unfortunately, we can't use the "user" bit in the page tables to control whether a page table entry is "global" or "asid" specific, since the vector page is mapped as "user" accessible but is not process specific.

2005-08-09[NET]: Fix memory leak in sys_{send,recv}msg() w/compatAndrew Morton
From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall! This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a new iovec structure. Only the one from sys_sendmsg() is free'ed. I wrote a simple test program to confirm this after identifying the problem: http://davej.org/programs/testsendmsg.c Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as it also calls verify_compat_iovec() but expects it to malloc internally.
