valid Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

2009-01-15sgi-xp: eliminate false detection of no heartbeatDean Nelson1-1/+1
After XPC has been up and running on multiple partitions for any length of time, if XPC on one of the partitions is stopped and restarted (either by a rmmod/insmod or a system restart), it is possible for the XPCs running on the other partitions to falsely detect a lack of heartbeat from the XPC that was just restarted. This false detection will occur if the restarted XPC comes up within the five-seconds preceding one of the other XPC's heartbeat check (which occurs once every twenty seconds). The detection of no heartbeat results in the detecting XPC deactivating from the just restarted XPC. The only remedy is to restart one of the XPCs and hope that one doesn't hit this five-second window on any of the other partitions.
