This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

In light of the recent pagefault and filemap_copy_from_user work I've gone
through all the arch pagefault handlers to make sure the inc_preempt_count()
'feature' works as expected.
Several sections of code (including the new filemap_copy_from_user) rely on
the fact that faults do not take locks under increased preempt count.

show_mem() was not correctly handling holes in the memory
map. It was treating the freed sections of the map as
though they contained valid struct page entries. This
could cause incorrect debugging output or even a kernel
panic.
This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory. show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

This is a rework of the ixp4xx irq_chip implementation. The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework. The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().
This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

In order to initialize the serial console early, the atmel_serial
driver had to do a hack where it compared the physical address of the
port with an address known to be permanently mapped, and used it as a
virtual address. This got around the limitation that ioremap() isn't
always available when the console is being initalized.
This patch removes that hack and replaces it with a new "regs" field
in struct atmel_uart_data that the board-specific code can initialize
to a fixed virtual mapping for platform devices where this is possible.
It also initializes the DBGU's regs field with the address the driver
used to check against.
On AVR32, the "regs" field is initialized from the physical base
address when this it can be accessed through a permanently 1:1 mapped
segment, i.e. the P4 segment.
If regs is NULL, the console initialization is delayed until the "real"
driver is up and running and ioremap() can be used.
