The stop_self thing is accessed unconditionally from pSeries_setup.c

This will get rid of the stack recursion possibility that can occur if
an IRQ happens to hit the IRQ return path right after we've reset
preempt_count() to 0 and are about to disable interrupts again.
Trivially fixed by just moving the preempt count update to inside the
interrupt disable.

This makes the current PREEMPT_ACTIVE method fully work for IRQ
recursions.

Avoid naming confusion concerning "pc_debug" which is widely used by drivers
be renaming the PCMCIA "driver services" variant to ds_pc_debug. The module
parameter stays the same, thanks to module_param_named().

This patch does a few cleanups of arch/ppc64/kernel/prom_init.c, making
the RTAS instanciation code more readable & more robust, fixing a bug
in the code bringing in additional CPUs (would work with IBM firmware,
but not with another firmware of an upcoming platform), plus remove some
old commented out cruft left-over from the big cleanup.

This patch reworks the code that deals with matching PCI devices
with Open Firmware device nodes. This code made several incorrect
assumptions and can be simplified significantly. The main functional
difference now is that PHBs are no longer special cased, but that
shouldn't cause any specific problem.

It also fixes a problem where u3_iommu.c wouldn't work for PCI
devices that lacked a matching OF device node.

This patch fixes a few issues in the ppc64 pci code, notably some
incorrect parsing of Open Firmware "ranges" when setting up host
bridge resources that would cause a problem with some future
platforms, a default mapping of the ISA IOs if the OF "isa" node
lacks a "ranges" property, and a safeguard in pci_scan_all_fns()
in case a pci<->OF node mapping cannot be established.

This patch applies on top of previously posted "ppc64: Move PCI IO mapping
from pSeries_pci.c to pci.c".

It does cosmetic cleanups & add some debug macros to pci.c without actually
changing any functionality. Further patches against ppc64 pci.c that I'll
post will be against a file already patched with this one.

This patch adds a ppc64 implementation of the routine providing
the list of default 8250 serial ports. It provides a empty list
by default unless the platform code fills it, and it provides
a generic function for user by Open Firmware based machines which
fills the list based on serial ports found in the OF device-tree.

It depends on the previous patch adding the generic support for
this to the 8250 driver.

This patch adds an optional callback for the 8250 driver to request the
list of legacy port via a function call instead of relying on a #define
of an array.

This finally allows to fix the problem of platforms like ppc and ppc64
for which the same kernel can boot machines with and without a 8250, and
is necessary to properly deal with a new platform coming to ppc64 which
has a 8250 but with different irq numbers.

This patch replaces the open_pic IRQ controller driver with a new
version rewritten from scratch, called "mpic" (this is the name of
IBM's open_pic implementation and also the only one actually used
on any platform).

It is smaller, hopefully more readable, supports the various variants
of the cell in a single driver (open_pic_u3.c is gone), and adds
optional support for the workaround of U3 mpic beeing used along with
IO-APICs on HyperTransport (the eval board will uses that, among
others).

The file didn't compile, and the ALSA CVS tree
had dropped the bitfield signedness fixes.

Now that spinlocks are uninlined, it is silly to keep the
BKL inlined. And this should make it a lot easier for people
to play around with variations on the locking (ie Ingo's
semaphores etc).
