This patch makes the following needlessly global functions static:
- nmi_int.c: profile_exceptions_notify()
- nmi_timer_int.c: profile_timer_exceptions_notify()

Removes the un/set_nmi_callback and reserve/release_lapic_nmi functions as
they are no longer needed. The various subsystems are modified to register
with the die_notifier instead.
Also includes compile fixes by Andrew Morton.

Incorporates the new performance counter reservation system in oprofile.
Also cleans up a lot of the initialization code. The code original zero'd
out every register associated with performance counters regardless if those
registers were used or not. This causes issues with the nmi watchdog.
Now oprofile tries to reserve registers and gives up if it can't get them.

Add it for P4 model 6 - reported to work and have a similar PMU to
earlier P4s.
Add an p4force=1 module override parameter for future use.
We had a discussion about that earlier - it's a trade off between the
PMU staying compatible or not. I think the force parameter is a
reasonable compromise.

nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.
Other archs aren't quite as clever: they assume 100. I suggest to
normalize them all to 1000.

The i386 OProfile code has a function named nmi_exit(), which collides with
the nmi_exit() macro in linux/hardirq.h. At the moment, we get away with
it, because hardirq.h isn't included in the oprofile code. I hit this as a
bug when working with a patch which (indirectly) adds a #include of
hardirq.h to oprofile.
Regardless, the name collision is probably not a good idea, so this patch
fixes it, renaming the oprofile function to op_nmi_exit(). It also renames
the nmi_init() and nmi_timer_init() functions similarly, for consistency.

I thought I'm done with fixing u32 vs. pm_message_t ... unfortunately
that turned out not to be the case as Russel King pointed out. Here are
fixes for Documentation and common code (mainly system devices).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
