patch db220b234da9f183b127b9c3077c253b94756e35 in mainline.
pci_device_to_OF_node() returns the device node attached to a PCI device,
but doesn't actually grab a reference - we need to do it ourselves.

patch ba02946a903015840ef672ccc9dc8620a7e83de6 in mainline
Its legal for the stfiwx instruction to have RA = 0 as part of its
effective address calculation. This is illegal for all other XE
form instructions.
Add code to compute the proper effective address for stfiwx if
RA = 0 rather than treating it as illegal.

On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error:
xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20
In a desperate attempt to get a changelog entry in 2.6.23, I took a look
into it.
It turns out we are passing a real and not a virtual irq into
get_irq_server. This works for the case where hwirq < NR_IRQS and we
set virq = hwirq. In my case however hwirq = 590082 and we try and
access irq_desc[590082], slightly past the end at 512 entries.
Lucky we ship lots of memory with our machines.

The commit 8b6f50ef1d5cc86b278eb42bc91630fad455fb10 seems to have
been affected by a mismerge of a duplicate patch
(d054b36ffd302ec65aabec16a0c60ddd9e6b5a62) - both the
spufs_dir_contents and spufs_dir_nosched_contents have been given
write-only signal notification files.
This change reverts the spufs_dir_contents array to use the

When PTRACE_O_TRACEEXEC is used, a ptrace call to fetch the registers at
the PTRACE_EVENT_EXEC stop (PTRACE_PEEKUSR) will oops in CHECK_FULL_REGS.
With recent versions, "gdb --args /bin/sh -c 'exec /bin/true'" and "run" at
the (gdb) prompt is sufficient to produce this. I also have written an
isolated test case, see https://bugzilla.redhat.com/show_bug.cgi?id=301791#c15.
This change fixes the problem by clearing the low bit of pt_regs.trap in
start_thread so that FULL_REGS is true again. This is correct since all of
the GPRs that "full" refers to are cleared in start_thread.

[POWERPC] Move serial_dev_init to device_initcall()

With the I/O space rewrite by BenH, the legacy_serial serial_dev_init()
initcall is now called before I/O space is setup, but it's dependent on
it being available.
Since there's no way to make dependencies between initcalls, we'll just
have to move it to device_initcall(). Yes, it's suboptimal but I'm not
aware of any better solution at this time, and it fixes a regression
from 2.6.22.

The location code is not guaranteed to be unique, so we might get bus_id

On PS3, A storage device may show up in the repository before the hypervisor
has finished probing:
- If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY,
- If its regions are being probed, it shows up as having zero regions.
If any of these happen, consider the device not yet present. The storage
probe thread will retry later.
This fixes the timing-dependent problem where a kernel booted from FLASH ROM
sometimes cannot find the hard disk.

does not make the master run control available to Linux.
This change makes SPE apps work again by disabling changes to the

interrupt.
The Cell BE Architecture spec states that the SPU MFC Class 0 interrupt
is edge-triggered. The current spu interrupt handler assumes this
behavior and does not clear the interrupt status.
The PS3 hypervisor visualizes all SPU interrupts as level, and on return
from the interrupt handler the hypervisor will deliver a new virtual
interrupt for any unmasked interrupts which for which the status has not
been cleared. This fix clears the interrupt status in the interrupt
handler.

This fixes a major bug which was happening when a SPU thread advances
its execution right after being restored to a SPU. A potentially
outdated NPC value was being (re)written to the SPU.
So, spu_run_init, in this case, was either not doing anything relevant,
or breaking the execution of the SPU thread.

This fixes a regression introduced with 2.6.23-rc4 after on some
confusion about the device tree interfaces.
IBM QS21 device trees provide "physical-id", so we changed the code to
run on that and remain compatible with all IBM machines.
However, the Toshiba Celleb device tree provides the "unit-id" property,
which was in the Linux code, but never used in this way on IBM hardware.
Legacy device tree used the reg property for the physical id of an spe.
This patch fixes find_spu_unit_number to look for the spu id in that order.
The length is checked to avoid misinterpretation in case the attributes
unit-id or reg do not contain the id.

When we flush register state for FP, Altivec, or SPE in flush_*_to_thread
we need to respect the task_struct that the caller has passed to us.
Most cases we are called with current, however sometimes (ptrace) we may
be passed a different task_struct.
This showed up when using gdbserver debugging a simple program that used
floating point. When gdb tried to show the FP regs they all showed up as
0, because the child's FP registers were never properly flushed to memory.

This partially reverts edd0622bd2e8f755c960827e15aa6908c3c5aa94.
It turns out that the part of that commit that aimed to ensure that we
created an SLB entry for the kernel stack on secondary CPUs when
starting the CPU didn't achieve its aim, and in fact caused a
regression, because get_paca()->kstack is not initialized at the point
where slb_initialize is called.
This therefore just reverts that part of that commit, while keeping
the change to slb_flush_and_rebolt, which is correct and necessary.

The Cell Broadband Engine has a method of injecting a
system-reset-exception from an external source into the
operating system, which should trigger the regular behaviour
of entering xmon or kdump.
Unfortunately, the exception handler cannot distinguish it from
other interrupt causes by the SRR1 register, which gets used
for this on Power 6 and others.
IBM Blade servers that want to support triggering the
system reset exception using a pinhole button in the front
panel therefore use an extra register to determine the
reset cause.

Legacy device tree used the reg property for the physical id of an
spe. On newer device tree layouts the reg property contains the
"correct" value in the reg attribute. So there has been intoduced the
"physical-id" on newer devicetree layouts. The id is stored by
spu_manage into the spu struct as spe_id. cbe_thermal has been
changed to use the spu->spe_id. There's no need for the thermal code
to check devicetree attributes for itself.

The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function. Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:
PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15
Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.
Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.
Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

The 440 family of processors don't have a tlbie instruction. So, we
implement TLB invalidates by explicitly searching the TLB with tlbsx.,
then clobbering the relevant entry, if any. Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler. Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries
which needed to be invalidated.
This fixes the problem in both arch/ppc and arch/powerpc by inhibiting
interrupts (even critical and debug interrupts) across the relevant
instructions.

My "slices" address space management code that was added in the 2.6.22
implementation of get_unmapped_area() doesn't properly check that the

create VMAs that aren't a multiple of the huge page size with hugetlbfs
(since hugetlbfs entirely relies on get_unmapped_area() to do that
checking) which leads to a kernel BUG() when such areas are torn down.

powerpc has a couple of bugs in the usage of dma_masks that tend to
break when drivers explicitly try to set a 32-bit mask for example.
First, the code that generates the pci devices from the OF device-tree
doesn't initialize the mask properly, then our implementation of
set_dma_mask() was trying to validate the -previous- mask value, not the
one passed in as an argument.

This reverts commit 3baee955953957be5496cd28e9c544d9db214262.
That commit was a mistake from the start; I added mdio type to the
