A discontigmem compilation fix From Bill Irwin

- Don't convert READA into READ in ll_rw_block().

This patch basically just renames usages of CONFIG_MULTIQUAD to
CONFIG_X86_NUMAQ. The original multiquad option covered a variety
of sins, and just made a mess (my fault). After extensive community
discussion, this is the naming scheme everyone agreed to - the
CONFIG_X86_NUMAQ option already exists, we're just renaming usages
of MULTIQUAD to it, and removing the MULTIQUAD option.

Stuff that's really to do with clustered APIC mode is put under
CONFIG_CLUSTERED_APIC instead, as it's not specific to the NUMA-Q.

Note that the definitions of clustered_apic_mode are still duplicated,
so the changes appear twice.  I'm not making it worse, just haven't
fixed this one yet, will do that next.

Patch was written by Matt Dobson.

Or in this case two.  This makes the migration and ksoftirq threads
match the naming convention of the workqueue threads.

Apply it and marvel at how neater a ps looks.

I tried building the aacraid driver in 2.5.41 and got an error
saying that O_TARGET usage was obsolete.  The following change
to the Makefile allows me to build.

Adds missing return values checking of
misc_register(), scsi_register(), request_region()
and does some code cleanup in the process..

As per the FIXME. Work done by Eric Blade

Just reconfigure on resume..

cpqarray uses disk_alloc instead of alloc_disk.  Same typo is in cciss,
rd.c sets ->first_minor to 0 for all units and HD_IRQ definition is
needed if CONFIG_BLK_DEV_HD is defined.

This makes sure we clear the user_tid in copy_thread, and that we
don't pass a bogus tid parameter in sys_clone when the CLONE_SETTID
and CLONE_CLEARTID flags are clear.

This also puts the file in include/asm-ppc/offsets.h rather
than arch/ppc/kernel/asm-offsets.h.  This changes PPC to do things
similarly to other ports, and makes make -j work reliably.
