Hi Matt !
The IBM PowerStation is a machine similar in design to our JS21 blades,
which uses an HT2000 bridge with it's dual 5780 TG3's.
I started investigating recently a problem where with recent kernels,
the machine will appear to freeze every second or two for a second
or two. The freeze

I've prepared the patch to fix the problem being discussed. It adds a field
flags to struct irq_chip. If IRQ_CHIP_UNMASK_ACK is set in this field,
acknowledge is performed before unmasking.
The patch is against 2.6.26

The watchdog driver mpc8xx_wdt.c was a device interface to
arch/ppc/syslib/m8xx_wdt.c for MPC8xx hardware. Now that ARCH=ppc is
gone, this driver is of no more use. For ARCH=powerpc, MPC8xx hardware
is supported by mpc8xxx_wdt.c.

Thanks for your patch, and sorry for not replying earlier.
It looks good from a functionality perspective, I just have
some style comments left
Hi all,
Most patches that were needed to support QE USB Host were merged during
2.6.27 merge window, and only three more patches left over. Here they
are.
David, could you bear with gpio_to_chip() exported function, just as
a stopgap for a proper api?
Thanks,

We'll need this function to write platform-specific hooks to deal
with pin's dedicated functions. Quite obviously this will work only
for the platforms with 1-to-1 GPIO to PIN mapping.
This is stopgap solution till we think out and implement a proper
api (pinlib?).

qe_gpio_set_dedicated() is a platform specific function, which is used
to revert a pin to a dedicated function. Caller should have already
obtained the gpio via gpio_request().
This is needed to support Freescale USB Host Controller.

This patch changes powerpc to use the new bcd2bin/bin2bcd functions
instead of the obsolete BCD_TO_BIN/BIN_TO_BCD macros.
