This has been broken since May 2008 when Al Viro killed altroot support.
Since nobody has complained, it would appear that there are no users of
this code (A plausible theory since the main OSVs that support ia64 prefer
to use the IA32-EL software emulation).

Some current configs turn on GRU for ia64.  The GRU code does not
correctly load on boot on ia64 (GRU does continue to work for x86-64), so
changing the IA64 Kconfig to not select GRU on ia64 configs for now until
we have time to fix.

The patch contains Intel IOMMU IA64 specific code. It defines new
machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush
function, etc.

For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected,
dig_vtd is used for machinve vector. Otherwise, kernel falls back to
dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off"
can be used to force kernel to boot dig machine vector.

Changes to support a new platform in my lab.

This patch changes the generic_defconfig so it works on all sn2
platforms I have access to.  There is only one support configuration
which was not tested and that configuration is only a combination of two
tested configurations.  With this patchset applied, a generic kernel can
be booted on either a RHEL 5.2, RHEL5.3, or SLES10 SP1 root and operate.
All features needed by SGI's ProPack are also working.  I have not
tested all features of RHEL or SLES, but they do at least boot.

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

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

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!
