Leftovers from the kmap_atomic conversion

From Peter Chubb

OK, make it X86 only.  64-bit architectures now get it for free;
if/when PPC32 (the only other 32-bit architecture I can seriously imagine
needing it, except possibly s390) fixes do_div() and needs large block
support, then enable it back there again.

There isn't as far as I know a flag I can test in a config.in file
that distinguishes 64 from 32-bit architectures.  The intention was to
enable the choice of CONFIG_LBD where it made sense;  it doesn't make
sense for 64-bit architectures; and rather than enumerate all the
32-bit architectures, I just chose two that I knew were used in
servers currently.

Use 'p', not 'j'

Fix a couple of things for no-io-apic builds:

- mpparse.c wants BAD_APICID

- mpparse.c (an perhaps others) want Dprintk()

This fixes a recent dyslexicism in cpqarray.

Use cond_resched() instead, and add a comment to explain.

Thanks again to davem...

The following patch fixes 2 obvious typos. Thanks to davem and George
Anzinger for pointing them out.

Here's a patch to add an Andrew File System (AFS) driver to the kernel.
Currently it only provides read-only, uncached, non-automounted and
unsecured support.

This adds RxRPC support to Linux for use by the AFS filesystem

Someone adding tests for failed kmalloc's (which is fine in itself)
did so in a way that would leave some PCMCIA data structures in
inconsistent states... and also introduced a fatal bug affecting
PCMCIA memory cards even when there are no kmalloc failures.

This is the RCU core patch from akpm's tree. It has been in his
tree since about 2.5.37-mm1 along with dcache_rcu and so far it has
worked fine. For 2.5, I am hoping that we might get the following
RCU patches included -

1. rt_rcu - ipv4 routecache lookup. Davem agreed to include this patch
   if and when you include RCU core in your tree.

2. dcache_rcu (by Maneesh Soni) - dcache lookup avoiding dcache_lock as
   much as possible. This has been akpm's tree - stable and gives us
   good yield. I have been submitting this to Viro and I will publish
   some more benchmark numbers later to help decide on this.

This RCU core implements RCU APIs, call_rcu() and synchronize_kernel(),
by monitoring a per-CPU quiescent state (idle/user etc.) counter.
call_rcu() queues a callback to be invoked after all the CPUs have
gone through a quiescent state. Queuing is per-CPU and each per-CPU
batch gets a batch number. As batches get their turn, a global
cpu mask is used to keep track of CPUs pending quiescent state.
Checking for quiescent cycle is done by saving the per-CPU
counter at the beginning of the batch and then monitoring it for change
through the local timer interrupt handler.

Adds a raw_phys_apicid array that maps from the mps cpu number
to the apicid - this is needed because the apicids for Summit can be
larger than 32, and thus won't fit into the bitmap. Also adds little wrappers
to map neatly between the two.

Bumps up MAX_APICS for Summit.

Adds detection for summit machines from the MPS tables.
Prints a handy-dandy debug message telling you what kind of twisted
machine the kernel thinks you have.

This one sets up the apic broadcast id (the maximum allowable apic address)
properly for whichever platform. It also abstracts out check_apicid_used,
because that check doesn't work on Summit. Oh, and I bumped up
MAX_IO_APICS, but only for NUMA x86 platforms.

This puts the DFR (desination format register) value into a #define, and
calculates the LDR (logical desitination register) correctly dependant
on platform. Similarly for TARGET_CPUS.

This just adds the config option for summit, and it's Config.help entry,
puts the hooks for the new mach_apic.h subarch file into the right
places, and creates empty shells of the header files.
