Linus,

Please do:

git pull \
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git merge

to get some more bug fixes for powerpc, mostly for various embedded
platforms. The bulk of the changes are once again in the defconfigs.

Thanks,
Paul.

[POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet works

This gets the FEC ethernet driver working again on the lite5200
platform.

The FEC driver is also compatible with the MPC5200, not only with the
MPC5200B, so this adds a suitable entry to the driver's match list.
Furthermore this adds the settings for the PHY in the dts file for the
Lite5200. Note, that this is not exactly the same as in the
Lite5200B, because the PHY is located at f0003000:01 for the 5200, and
at :00 for the 5200B. This was tested on a Lite5200 and a Lite5200B,
both booted a kernel via tftp and mounted the root via nfs
successfully.

[POWERPC] Fix rtas_flash procfs interface

Handling of the proc_dir_entry->count was changed in 2.6.24-rc5.
After this change, the default value for pde->count is 1 and not 0 as
before. Therefore, if we want to check whether our procfs file is
already opened (already in use), we have to check if pde->count is
greater than 2 rather than 1.

[POWERPC] Fix deadlock with mmu_hash_lock in hash_page_sync

hash_page_sync() takes and releases the low level mmu hash
lock in order to sync with other processors disposing of page
tables. Because that lock can be needed to service hash misses
triggered by interrupt handlers, taking it must be done with
interrupts off. However, hash_page_sync() appears to be called
with interrupts enabled, thus causing occasional deadlocks.

We fix it by making sure hash_page_sync() masks interrupts while
holding the lock.

[POWERPC] Fix iSeries hard irq enabling regression

A subtle bug sneaked into iSeries recently. On this platform, we must
not normally clear MSR:EE (the hardware external interrupt enable)
except for short periods of time. Taking an interrupt while
soft-disabled doesn't cause us to clear it for example.

The iSeries kernel expects to mostly run with MSR:EE enabled at all
times except in a few exception entry/exit code paths. Thus
local_irq_enable() doesn't check if it needs to hard-enable as it
expects this to be unnecessary on iSeries.

However, hard_irq_disable() _does_ cause MSR:EE to be cleared,
including on iSeries. A call to it was recently added to the
context switch code, thus causing interrupts to become disabled
for a long periods of time, causing the iSeries watchdog to kick
in under some circumstances and other nasty things.

This patch fixes it by making local_irq_enable() properly re-enable
MSR:EE on iSeries. It basically removes a return statement here
to make iSeries use the same code path as everybody else. That does
mean that we might occasionally get spurious decrementer interrupts
but I don't think that matters.

Another option would have been to make hard_irq_disable() a nop
on iSeries but I didn't like it much, in case we have good reasons
to hard-disable.

Part of the patch is fixes to make sure the hard_enabled PACA field
is properly set on iSeries as it used not to be before, since it
was mostly unused.

[POWERPC] 83xx: Fix wrong USB phy type in mpc837xrdb dts

Due to chip constraint MPC837x USB DR module can only use
ULPI and serial PHY interfaces. The patch fixes the wrong

This patch fixes USB malfunctioning on the MPC837xE-RDB boards.

Similar patch has been already applied for the MDS boards:
