This updates the sn2_defconfig file for the Altix 330 hardware, enables
the AGP graphics for the SGI Prism, and removes prompts for the remainder
of the new features.  Greg Edwards reviewed the changes.

This patch introduces 4-level page tables to ia64.  I have run
some benchmarks and found nothing interesting.  Performance has
consistently fallen within the noise range.

It also introduces a config option (setting the default to 3
levels).  The config option prevents having 4 level page
tables with 64k base page size.

The config option 'CONFIG_ACPI_DEALLOCATE_IRQ' is no longer
needed. This patch removes it.

Delete the ability to build an ACPI kernel that does
not include PCI support.  When such a machine is created
and it requires a tuned kernel, send a patch.

Build issues were mostly in the ACPI=n case -- don't do that.
Select ACPI from IA64_GENERIC.
Add some missing dependencies on ACPI.

Mark BLACKLIST_YEAR and some laptop-only ACPI drivers
as X86-only.  Let me know when you get an IA64 Laptop.

This patch removes the CONFIG_IA64_SGI_SN_SIM option entirely, allowing
any kernel bootable on sn2 to also be booted in the simulator.

Boot tested on Altix and HP rx2600.

Altix patch to enable use of vgacon driver on that platform.  Depends on the
PCDP generalization patch discussed at:

This will at least suppress one prompt that users would have received the
first time they compile with the new DISCONTIG arch option.  They'll still
get the "Memory Model" prompt, but 99% of them will have the default work
there.

The SGI IOC4 I/O controller chip drivers are currently all configured by
CONFIG_BLK_DEV_SGIIOC4.  This is undesirable as not all IOC4 hardware features
are needed by all systems.

This patch adds two configuration variables, CONFIG_SGI_IOC4 for core IOC4
driver support (see patch 1/3 in this series for further explanation) and
CONFIG_SERIAL_SGI_IOC4 to independently enable serial port support.

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!
