While the sysctl variable is being worked out in the general kernel, here is
an interim patch which allows boot-time/dynamic control over the use of
PAL_HALT_LIGHT in the idle-loop.

SN2 doesn't fully support level triggered interrupts.  As a
workaround, we need this patch to force another interrupt if the line
is still high after a handler completes.

GCC v3.5 doesn't like it when a function gets cast to a
function-pointer with a different signature.  In fact, it exterts
extreme prejudice in this case and replaces the call-site with a call
to __builtin_trap()!  Fix this by providing appropriately typed
dummy-functions for the macvec operations as needed.

While at it, also clean up some machvec handlers which weren't used anywhere.

Older versions of the linker do not handle cross-segment segment-relative
relocations properly.  This becomes a real problem when the linker decides
to put .text and .text.init into different segments (for whatever reasons)
because in that case, broken linkers will produce a broken unwind section,
which can cause nasty Heisenbugs, where, for example, unwinding may or may
not work depending on the exact value of the IP in a function.

The config ACPI helptext isn't used because the option is never
presented to the user.
ACPI_KERNEL_CONFIG is unused.
ACPI_INTERPRETER is now set in drivers/acpi/Kconfig.

This is a minor patch to get things setup so consoles can
work earlier.  (No change to consoles here, I just split this
out to make the diff easier to read.)

(io_port_init): New function, same old code to setup ia64_iobase
and legacy IO port space.
(setup_arch): Call io_port_init() and machvec_init() as early as
possible so consoles can work earlier.

Without this change, GCC thinks it's OK to clobber r13.  It doesn't do it
very often, but it's enough if it does it once and it turns out
acpi_bus_receive_event() had code that would trigger this issue.
Fix by declaring r13 as a global register variable.

We also need the following patch to build the generic_defconfig
after the DMA API change:

SN2 platforms provide oemdata in salinfo records.  The decode of that
oemdata is done via prom routines.  This patch provides the interface
from user space through the kernel into the prom to do the oem decode.

Apparently GCC sometimes fails to insert a stop-bit when re-using p14
after the spinlock directives, even though the register is clearly marked
as "clobbered".

Use the proper (and cleaner) probing API instead of the old
scsi_module.c hack, don't use the typedefs I plan to kill in 2.7 and
mark everything static

This Kconfig patch basically just makes ia64 look a little more like i386:
        - moves system type above processor type
        - moves PM & ACPI to a new top-level menu
        - moves PCI/PCMCIA to a new top-level menu

See this ChangeSet:

The MCA code is now slim enough that there isn't much point in keeping
CONFIG_IA64_MCA anymore.

The patch that moved and renamed consistent_dma_mask neglected
to fix up arch/ia64/hp/common/sba_iommu.c.

The last mod to fix the staircase printing - missed some bracing...

This fixes the CONFIG_DEBUG_INFO build on x86-64 (there were missing
.cfi_endprocs)

Also some minor cleanup in the exception stack handling.

There's an error in sys_swapon() that can cause slab corruption if you
pass in a bad specialfile pointer. getname() then returns
ERR_PTR(-EFAULT), but sys_swapon() doesn't clear name before calling
putname() on it (thus freeing 0xfffffff2, corrupting slab). An ltp test
case repeatedly crashed in later tests due to thus, irk.

This bug was discussed on linux-scsi a few weeks back, but it appears to
have slipped through the cracks. This fix was originally proposed by
Christoph Hellwig, but I am reposting it, since I have the hardware :-)

Anyway, the problem that this fixes is that megaraid doesn't set the
moduler owner for the host_template, this means that the module can be
removed, even when it is in use.

If the driver fails to load, we leave a 3c509 eisa directory
in sysfs.

No code changes, but lots of trivial whitespace cleaning, and
removal of a bogus set of 'defaults' at the bottom of the file.

Patch from Bjorn Helgaas

ACPI and HCDP tell us what IRQ the serial port uses, so there's
no need to have the driver probe for the IRQ.

Adds a generic implementation of 32 bit emulation for IPC system calls.  The
code is based on the existing implementations for sparc64, ia64, mips, s390,
ppc and x86_64, which can subsequently be converted to use this.
