ia64 needs to include i2c by hand

Kills a warning and a false sense of safety by removing the volatile
qualifier on cpu_to_node_map[] and node_to_cpu_mask[].  Also fix the
printk for total processors since num_online_cpus() can return an int or
a long depending on the value of NR_CPUS.

This patch just updates the cast in irq_lsapic.c to use the cpumask_t
type for the noop cast assignment to smp_affinity.

	correctly even on 32-bit hosts. As an added bonus, it's faster,
	too.  Run "unwcheck" by default, but for now, don't let unwcheck
	errors cause the kernel build to fail.

This patch gets rid of some superfluous printk's which get tedious on
machines with insane number of CPUs.  The virtual/physical address bit
info is already available via /proc/pal, so there is no need to print
it at boot- time.

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.)

      modular ACPI device drivers.

Fix system type selection to workaround menuconfig bug (select "HP",
get "HP-simulator").

I fixed the code to compile with CONFIG_ACPI_NUMA and
!CONFIG_DISCONTIG since it's actually possible to compile that
configuration as well as cleaned up the #include usage a litte.

	dropped from GCC at some point in the future.

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.

	arguments.

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.

Just a quick update for the sn2_defconfig file now that some more config
options have been added.

This patch adds a little noise on the console.  I like to see this
info because it matches up with the AGPGART aperture info later on.

	Here's a generic_defconfig that works on all the ia64
	platforms I'm aware of, and we can always update it if it's
	missing a driver or two.  Compile tested 'make compressed' and
	'make modules', and boot tested on sn2, and I think Alex boot
	tested on an HP machine.

We must not mark the process TASK_STOPPED early, because
that might allow a signal to wake it up before we actually
got to the "wake_up_forked_process()" state. Total confusion
would happen.

Make wake_up_forked_process() verify the new world order.

For a laugh we moved the BSS and our world exploded. Turns out we zero
from __bss_start to _end. Add __bss_stop to our section definitions so
we can use it instead.
