This passes pm_message_t down to PCI drivers.  Ugly translation code can be
removed and this will allow PCI devices to do right thing during swsusp
snapshot -- like not unneccessarily blanking display.

Only obscure /sysfs code passes anything but 3 to pci_device_suspend,
anyway, so this is pretty close to a nop.

Fix SMP race in NMI watchdog on i386/x86-64

Fix a long standing SMP Setup race in the NMI watchdog.  The watchdog would
tick from very early and check if all CPUs increase their timer interrupts.
For that it would check the cpu_online_map.  Now if a CPU took too long to
boot the watchdog would trigger prematurely because the CPU didn't increase
its timer count yet.

Fix is to check cpu_callin_map instead of cpu_online_map because the first is
only set when a CPU started its timer interrupt.

I fixed it on i386 and x86-64.

Description of the problem from Manpreet Singh. Thanks.

Fix a long standing race in x86-64 SMP TLB handling.  When a mm is freed and
another thread exits to a lazy TLB thread (like idle) the freed user page
tables would be still kept loaded in the idle thread.  When an interrupt does
a prefetch on NULL the CPU would try to follow it and read random data. 

This could lead to machine checks on Opterons in some cases.

Credit goes to some unnamed debugging wizards at AMD who described the
problem.  All blame to me.  I did the fix based on their description.

The g5 code has special hooks to "hide" some PCI devices when they are off.

Currently, this code involves some calls to match a pci_dev from the open
firmware node and such things that are causing some problems with the
latest version of my sungem driver who wants to do some of this in atomic
contexts.

This patch moves that to a list of struct device_node instead, which also
ends up simplifying the code.

Later, I'll go back to manipulating PCI devices in a clean way when Brian
King's PCI blocking patch gets in, but only after I change sungem again to
never call these in atomic context.  This is a 3 step transition basically

When the update_process_times call was moved out of do_timer for the UP case,
the replicator didn't track down the hiding and just added ifndef SMP.

This removes the ifdefs and the indirection of calling another file for one
function in a third file.

I also removed the per-cpu multipler and counter.  On some architectures (x86
and sparc64) these are set via /proc/profile setup_profiling_timer to increase
the timer interrupt by a factor over HZ.  However, this was not not
implemented for ppc (like several other architectures), so it was just
decrementing, testing, and setting per-cpu variables back to 1.

There is a problem in the TLB Miss (and Error, as they jump to the Miss
handler) handlers.  The problem is that when an app spans more than one L1
entry, we don't have all of the correct information, and do_page_fault()
things a protection fault happened, when it didn't really.  The fix for this
is to modify the handlers slightly to force a TLB Error in this case.

On most embedded PPC systems we either have a core CPU and chipset (MPC10x,
TSI10x, Marvell, etc.) or a system-on-chip device (4xx, 8xx, 82xx, 85xx,
etc.).  Some of these sub-archs have been using the On Chip Peripheral
(OCP) driver model.  The functionality that OCP provide has been replaced
by the generic driver model and platform_device.  Also, some of these
device may exist across a number of architectures (PPC, MIPS, ARM) such
that some information that is shared between the architecture and driver
needs to exist outside of either.

The ppc_sys changes add a standard way for PowerPC systems to describe the
devices and systems that exist in the sub-arch.  Additionally, we are able
to discover which system we are and manage which devices are actually
registered and any platform specific fixups that may be needed.
