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.
Issue reported by Sergei Sharonov.

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
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.

set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().
This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.

little or no use of the contents. Move the contents to a local
