Adds the ability to disability packet split at compile time and use the legacy receive path on PCI express hardware. Made this a CONFIG option and modified the Kconfig, to reflect the new option.

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.

PNP and PNPACPI turned on
i8042 recently changed from ACPI to PNP detection. Without PNP, it
probes legacy I/O ports for the keyboard controller, which causes an
MCA on HP boxes.
Also, I'm about to remove 8250_acpi.c, so we'll need PNP to detect
non-PCI serial ports. Until 8250_acpi.c is removed, some systems
will see serial ports reported twice (once from 8250_acpi.c and again
from 8250_pnp.c). This is harmless.
PNPACPI is still marked EXPERIMENTAL, but I'm not aware of any
outstanding issues on ia64.
IDE_GENERIC turned off (except for SGI simulator, all ia64 IDE is PCI)
ide-generic probes compiled-in legacy I/O ports for IDE devices, which
again causes an MCA. It would be nicer to just get rid of all the
legacy junk from include/asm-ia64/ide.h, but that is a bit riskier
because it could break ide-cs and the HDIO_REGISTER_HWIF ioctl
(http://www.ussg.iu.edu/hypermail/linux/kernel/0508.2/0049.html).
Here's the essence of the patch:
-# CONFIG_PNP is not set
+CONFIG_PNP=y
+CONFIG_PNPACPI=y
-CONFIG_IDE_GENERIC=y
+# CONFIG_IDE_GENERIC is not set
Tested on tiger, bigsur, and zx1.

Turn off the QLOGIC_FC driver. Supposedly qla2xxx should support
these devices. Do any ia64 machines have one of these devices as
the boot device?

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 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.

Do arch/ia64/defconfig by hand.

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.

Refresh arch/ia64/defconfig, as it was getting a bit stale. The only
manual changes I made were:
CONFIG_SCSI_SATA=y needed for some Altix base I/O cards
CONFIG_SCSI_SATA_VITESSE=y
CONFIG_DM_MULTIPATH=m the rest are already modules
CONFIG_FUSION_SPI=y new driver breakout
CONFIG_FUSION_FC=m
CONFIG_SGI_TIOCX=y enable some other SGI drivers
CONFIG_SGI_MBCS=m
CONFIG_AGP_SGI_TIOCA=m
Boot tested on Altix, HP rx2600 and Intel Tiger

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!
