2006-12-09[PATCH] i386: export smp_num_siblings for oprofileRandy Dunlap
oprofile uses smp_num_siblings without testing for CONFIG_X86_HT. I looked at modifying oprofile, but this way is cleaner & simpler and I didn't see a good reason not to just export it when CONFIG_SMP.

2006-12-09[PATCH] x86: Work around gcc 4.2 over aggressive optimizerAndi Kleen
The new PDA code uses a dummy _proxy_pda variable to describe memory references to the PDA. It is never referenced in inline assembly, but exists as input/output arguments. gcc 4.2 in some cases can CSE references to this which causes unresolved symbols. Define it to zero to avoid this.

2006-12-09[PATCH] x86: Fix boot hang due to nmi watchdog init codeRavikiran G Thirumalai
2.6.19 stopped booting (or booted based on build/config) on our x86_64 systems due to a bug introduced in 2.6.19. check_nmi_watchdog schedules an IPI on all cpus to busy wait on a flag, but fails to set the busywait flag if NMI functionality is disabled. This causes the secondary cpus to spin in an endless loop, causing the kernel bootup to hang. Depending upon the build, the busywait flag got overwritten (stack variable) and caused the kernel to bootup on certain builds. Following patch fixes the bug by setting the busywait flag before returning from check_nmi_watchdog. I guess using a stack variable is not good here as the calling function could potentially return while the busy wait loop is still spinning on the flag.

XFRMGRP_REPORT uses 0x10 which is a group that belongs to events. The correct value is 0x20.

2006-12-08[NETPOLL]: make arp replies through netpoll use mac address of senderNeil Horman
Back in 2.4 arp requests that were recevied by netpoll were processed in netconsole_receive_skb, where they were responded to using the src mac of the request sender. In the 2.6 kernel arp_reply is responsible for this function, but instead of using the src mac address of the incomming request, the stored mac address that was registered for the netconsole application is used. While this is usually ok, it can lead to failures in netpoll in some situations (specifically situations where a network may have two gateways, as arp requests from one may be responded to using the mac address of the other). This patch reverts the behavior to what we had in 2.4, in which all arp requests are sent back using the src address of the request sender.

2006-12-08[PATCH] dm: mpath: use noflush suspendingKiyoshi Ueda
Implement the pushback feature for the multipath target. The pushback request is used when: 1) there are no valid paths; 2) queue_if_no_path was set; 3) a suspend is being issued with the DMF_NOFLUSH_SUSPENDING flag. Otherwise bios are returned to applications with -EIO. To check whether queue_if_no_path is specified or not, you need to check both queue_if_no_path and saved_queue_if_no_path, because presuspend saves the original queue_if_no_path value to saved_queue_if_no_path. The check for 1 already exists in both map_io() and do_end_io(). So this patch adds __must_push_back() to check 2 and 3. Test results: See the test results in the preceding patch.
