PNP devices can use shared interrupts, so check to see whether we'll need
SA_SHIRQ for request_irq().
The builtin PDH UART on the HP rx8640 is an example of an ACPI/PNP device
that uses a shareable level-triggered, active-low interrupt. The interrupt
can be shared in very large I/O configurations or by artificially lowering
IA64_DEF_LAST_DEVICE_VECTOR.

Claim the WACF005 device. This is the pen display pointing device on
the HP Compaq tc1100 Tablet PC. More information about using this
device, including using it as an X pointer device:
http://www.theory.bham.ac.uk/staff/schofield/linux/tc1100/
Christopher Kemp <ck231@cam.ac.uk> did the legwork of determining that
the WACF005 is really just a plain old UART and doing an initial ACPI
driver (before we had PNPACPI), and David Ludlow <dave@adsllc.com>
confirmed that PNPACPI + the attached patch is now sufficient:
pnp: Device 00:05 activated.
ttyS4 at I/O 0x300 (irq = 4) is a 16550A

Add support for UARTs in MMIO space and clean up a little whitespace.
HP legacy-free ia64 machines need this.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
