the MCA non-recoverable, print the reason it could not recover.
This will make it easier to identify why the recovery code did

[IA64] enable dumps to capture second page of kernel stack
In SLES10 (2.6.16) crash dumping (in my experience, LKCD) is unable to
capture the second page of the 2-page task/stack allocation.
This is particularly troublesome for dump analysis, as the stack traceback
cannot be done.
(A similar convention is probably needed throughout the kernel to make
kernel multi-page allocations detectable for dumping)
Multi-page kernel allocations are represented by the single page structure
associated with the first page of the allocation. The page structures
associated with the other pages are unintialized.
If the dumper is selecting only kernel pages it has no way to identify
any but the first page of the allocation.
The fix is to make the task/stack allocation a compound page.

[IA64-SGI] - Reduce overhead of reading sn_topology
MPI programs using certain debug options have a long
startup time. This was traced to a "vmalloc/vfree" in
the code that reads /proc/sgi_sn/sn_topology. On large
systems, vfree requires an IPI to all cpus to do TLB
purging.
Replace the vmalloc/vfree with kmalloc/kfree. Although
the size of the structure being allocated is unknown, it
will not not exceed 96 bytes.

[IA64] IOC4 config option ordering
SERIAL_SGI_IOC4 and BLK_DEV_SGIIOC4 depend upon SGI_IOC4, and
SERIAL_SGI_IOC3 depends upon SGI_IOC3. Currently the definitions
are out of order in the config sequence.
Fix by including drivers/sn/Kconfig immediately after SGI_SN,
upon which SGI_IOC4 and SGI_IOC3 depend.

[IA64] Setup an IA64 specific reclaim distance
RECLAIM_DISTANCE is checked on bootup against the SLIT table distances.
Zone reclaim is important for system that have higher latencies but not for
systems that have multiple nodes on one motherboard and therefore low latencies.
We found that on motherboard latencies are typically 1 to 1.4 of local memory
access speed whereas multinode systems which benefit from zone reclaim have
usually more than 1.5 times the latency of a local access.
Set the reclaim distance for IA64 to 1.5 times.

It also fixes wrong definition of ia64_pci_legacy_write (type of `bus' is not
`pci_dev', but `pci_bus').
