It was possible to hotplug add a new cpu that was larger than numnode.
This meant we had a cpu with a node id that didnt have any NODE_DATA()
backing it.

The following patch catches this in numa_setup_cpu and forces the node to
0.  We also make a pass through all cpus at boot to look for the maximum
node id - this catches the case at boot.  As for hotplug, since the node
doesnt have any memory backing it (otherwise the node would have been
onlined) then we can assume the machine isnt configured for performance and
just force the cpu into node 0.

profile_hook unconditionally takes a read lock on profile_lock if kernel
profiling is enabled.  The lock protects the profile_hook notifier chain
from being written while it's being called.  The routine profile_hook is
called in a very hot path though: every timer tick on every CPU.  As you
can imagine, on a large system, this makes the cacheline containing
profile_lock pretty hot.  Since oprofile was the only user of the
profile_hook, I removed the notifier chain altogether in favor of a simple
function pointer with the help of John Levon.  This removes all of the
contention in the hot path since the variable is very seldom written and
simplifies things a little to boot.

Patch from Nicolas Pitre

This should be applied on top of patch #2154/1.

This maps the XIP kernel in the same virtual area as used for kernel
modules instead of the previous arbitrary location.  Doing so has the
advantage of having a well defined kernel address not conflicting
with the different definitions for VMALLOC_END, as well as making
modules loadable without any indirect long branch calls.  The work
on XIPable MTD also requires this with code marked __xipram for the
same reason.

This of course reduces the space available for kernel modules from
16MB to either 14MB or 12MB depending on the size of the resulting 
kernel but that shouldn't be a real issue at all, given that the
whole purpose behind XIP is to execute as much stuff from flash, 
which is better achieved by compiling drivers in the kernel directly.

Patch from Nicolas Pitre

This patch allows for the kernel to be configured for XIP.
A lot of people are using semi hacked up XIP patches already so
it is a good idea to have a generic and clean implementation 
supporting all ARM targets. The patch isn't too intrusive.

It involves:

- modifying the kernel entry code to map separate .text and .data
  sections in the initial page table, as well as relocating
  .data to ram when needed

- modifying the linker script to account for the different VMA and
  LMA for .data, as well as making sure that .init.data gets
  relocated to ram

- adding the final kernel mapping with a new MT_ROM mem type

- distinguishing between XIP and non-XIP for bootmem and memory
  resource declaration

- and adding proper target handling to Makefiles.

While at it, this also cleans up the kernel boot code a bit
so the kernel can now be compiled for any address in ram,
removing the need for a relation between kernel address and
start of ram.  Also throws in some more comments.

And finally the _text, _etext, _end and similar variables are now
declared extern void instead of extern char, or even extern int.
That allows for operations on their address directly without any
cast, and trying to reference them by mistake would yield an 
error which is a good thing.

Tested both configurations: XIP and non XIP, the later 
producing a kernel for execution from ram just as before.

     You are absolutely correct. That notice slipped by us and should not be in
