Kills a warning and a false sense of safety by removing the volatile

a long depending on the value of NR_CPUS.

[PATCH] ia64: move HCDP under serial console #ifdef
Currently you can select HCDP independent of serial console. This
doesn't seem very useful, and makes the setup_serial_hcdp() reference
unresolved if the serial driver is built as a module.
CONFIG_SERIAL_8250_CONSOLE is only selectable if the serial core is
built in (SERIAL_8250=y), so this patch makes sure we don't try to
call setup_serial_hcdp() unless it is actually built in to the kernel.
(I think we should also make HCDP selection dependent on
SERIAL_8250_CONSOLE=y in Kconfig; I'll send a separate patch
for that since it's not ia64-specific.)

[PATCH] ia64: sba_iommu update
This patch does a couple things:
* Allows iommu page size different than PAGE_SIZE. This was
largely done by Bjorn. The motivation for this is that sx1000
hardware officially only supports use of the iommu with a 4k
page size. Thus the default is now 4k for sx1000 and PAGE_SIZE
for zx1.
* Cleanup the runtime statistics gathering such that we can turn
it on for some info w/o impacting runtime performance.

When building a highly modular, non-generic kernel it can happen that
arch/ia64/lib/io.o is not included in the image because nothing built-in
needs __ia64_memcpy_fromio, etc., yet it may be called from a module. We
should force it to be linked in.

Fix for oops on rmmod caused by *_remove() function marked as __devinit
(and thus discarded after module initialization - if CONFIG_MODULES=y
and CONFIG_HOTPLUG is not set).
This patch changes __devinit to __devexit and adds __devexit_p() where
pointer to such function is used.
The only exception is au1000, where au1000_remove() is called from
cleanup_au1000() function - __devinit is jest removed there.
This fixes BUG-on-swapout for srmmu-based systems. The problem is
