I found a typo and what seems to be a run-on sentence in
arch/arm/common/dmabounce.c

Patch from Andrew Victor

This patch includes a few changes to the clock support on the
AT91RM9200.

1. Added definitions for Ethernet, MMC, TWI, USARTs, and SPI peripheral
clocks.

2. Replaced some hard-coded hex values with the text definitions in
at91rm9200_sys.h.

3. If the USB96M bit is set for PLLB, then the rate of PLLB is not
affected but only the USB Host/Device clocks which are derived from it.

Patch from Andrew Victor

If the timer interrupt is ever significantly delayed (or after the
system was suspended), the system could spin incrementing the time for
too long.
The fix is to replace the "do {} while" with a "while {}".

Patch from Lennert Buytenhek

On the IXDP2x00s, the NPU that is PCI master is always the egress
(i.e. 'master') NPU.  At least on the IXDP2800, both NPUs have flash,
so the ixp2000_has_flash() check in ixdp2x00_master_npu() is useless.

The xscale UART in the ixp2000 is basically just an 8250 UART (with

macros on the ixp2000.

Patch from Lennert Buytenhek

ixp2000 used to initially mark GPIO interrupts as invalid, and not
mark them valid until set_irq_type() was called, but this doesn't
work if you want to use request_irq() with the SA_TRIGGER_* flags.

So, just mark the GPIO interrupts valid from the beginning.  We
configure GPIOs as inputs when set_irq_type() is called anyway, so
this shouldn't be a problem.

Currently, if the kernels HZ value is greater than 100, delays with the udelay function are too short. This can cause trouble for instance with the zd1201 usb wlan driver.
