Jack Steiner identified a problem where XPC can cause a silent data corruption. On module load, the placement may cause the xpc_remote_copy_buffer to span two physical pages. DMA transfers are done to the start virtual address translated to physical. This patch changes the buffer from a statically allocated buffer to a kmalloc'd buffer. Dean Nelson reviewed this before posting. I have tested it in the configuration that was showing the memory corruption and verified it works. I also added a BUG_ON statement to help catch this if a similar situation is encountered.

This patch fixes a problem in XPC disengage processing whereby it was not seeing the request to disengage from a remote partition, so the disengage wasn't happening. The disengagement is suppose to transpire during the time a XPC channel is disconnecting, and should be completed before the channel is declared to be disconnected.

XPC (as in arch/ia64/sn/kernel/xp*) has a need to notify other partitions (SGI Altix) whenever a partition is going down in order to get them to disengage from accessing the halting partition's memory. If this is not done before the reset of the hardware, the other partitions can find themselves encountering MCAs that bring them down.

Some of the SN code & #defines related to compact nodes & IO discovery have gotten stale over the years. This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: NJack Steiner <steiner@sgi.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

When XPC is being shutdown (i.e., rmmod, reboot) it doesn't ensure that other partitions with whom it was connected have completely disengaged from any attempt at cross-partition memory references. This can lead to MCAs in any of these other partitions when the partition is reset. Signed-off-by: NDean Nelson <dcn@sgi.com> Signed-off-by: NTony Luck <tony.luck@intel.com>
