In struct device_node, the phandle is named 'linux_phandle' for PowerPC
and MicroBlaze, and 'node' for SPARC. There is no good reason for the
difference, it is just an artifact of the code diverging over a couple
of years. This patch renames both to simply .phandle.
Note: the .node also existed in PowerPC/MicroBlaze, but the only user
seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
look like the assignment between .linux_phandle and .node is
significantly different enough to warrant the separate code paths
unless ibm,phandle properties actually appear in Apple device trees.
I think it is safe to eliminate the old .node property and use
phandle everywhere.

A cell is firmly established as a u32. No need to do an ugly typedef
to redefine it to cell_t. Eliminate the unnecessary typedef so that

This patch fixes USB GPIOs numbers for MPC8569E-MDS boards, plus
according to the latest HW Getting Started Guide (rev 3.3, pilot
boards), USB "POWER" GPIO polarity has changed, it is no longer
inverted.
This patch makes USB Host somewhat work on pilot boards, though
there are still some problems with determining devices speed and
long bulk transfers.

The PCI-e addressing was originally patterned of the MPC8548CDS
which has PCI1, PCI2, and PCI-e. Since this board only has
PCI1 and PCI-e, it makes more sense to be similar to the MPC8568MDS
board. This does that by cutting the PCI/PCI-e I/O sizes from
16MB to 8MB and pulling the PCI-e I/O range back to 0xe280_0000
(the hole where PCI2 I/O would have been).
This also fixes a typo where an extra zero made an 8MB range a 128MB
range, removes the hole left by PCI2 from the aliases, and sets the
clocks to match the oscillators that are actually on the board.
With accompanying u-boot updates, PCI-e has been validated with
both a sky2 card (1148:9e00) and an e1000 card (8086:108b).

Patch f598282f5145036312d90875d0ed5c14b49fd8a7 exposed a problem in
powerpc MSI-X functionality, making network interfaces such as ixgbe
and cxgb3 stop to work when MSI-X is enabled. RX interrupts were not
being generated.
The problem was caused because MSI irq was not being effectively
unmasked after device initialization.

Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com>
Use preempt_schedule_irq to prevent infinite irq-entry and
eventual stack overflow problems with fast-paced IRQ sources.
This kind of problems has been observed on the PASemi Electra IDE
controller. We have to make sure we are soft-disabled before calling
preempt_schedule_irq and hard disable interrupts after that
to avoid unrecoverable exceptions.
This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of
the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered
and has to be restored in both cases.

The creation of the flattened device tree depended on the compiler
putting the constant strings for an object in a section with a
particular name. This was changed with recent compilers. Do this
explicitly instead.
Without this patch, iseries kernels may silently not boot when built with
some compilers.
