FUJITA Tomonori 46a7fa270a x86: make only GART code include gart.h
gart.h has only GART-specific stuff. Only GART code needs it. Other
IOMMU stuff should include iommu.h instead of gart.h.

Maciej W. Rozycki ecd29476ae x86: I/O APIC: remove parameters to fiddle with the 8259A
Remove the "disable_8254_timer" and "enable_8254_timer" kernel
parameters.  Now that AEOI acknowledgements are no longer needed for
correct timer operation, the 8259A can be kept disabled unconditionally
unless interrupts, either timer or watchdog ones, are actually passed
through it.

Jesse Barnes 15650a2f64 x86/PCI: fixup early quirk probing
On x86, we do early PCI probing to apply some quirks for chipset bugs.
However, in a recent cleanup (7bcbc78dea) a
thinko was introduced that causes us to probe all subfunctions of even single
function devices (a function was factored out of an inner loop and a "break"
became a "return").  Fix that up by making check_dev_quirk() return a value so
we can keep the factored code intact.

WARNING: arch/x86/kernel/built-in.o(.text+0x13a42): Section mismatch: reference to .init.data:

Warning was caused by access to the __initdata annotated variable
from the non-annotated static function check_dev_quirk().
check_dev_quirk() were only used from a function annotated
__init so add __init annotation to check_dev_quirk() to fix it.

Neil Horman c6b4832432 x86, kexec: force x86 arches to boot kdump kernels on boot cpu
Recently a kdump bug was discovered in which a system would hang inside
calibrate_delay during the booting of the kdump kernel.  This was caused
by the fact that the jiffies counter was not being incremented during
timer calibration.  The root cause of this problem was found to be a
bios misconfiguration of the hypertransport bus.  On system affected by
this hang, the bios had assigned APIC ids which used extended apic bits
(more than the nominal 4 bit ids's), but failed to configure bit 17 of
the hypertransport transaction config register, which indicated that the
mask for the destination field of interrupt packets accross the ht bus
(see section 3.3.9 of
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26094.PDF).
If a crash occurs on a cpu with an APIC id that extends beyond 4 bits,
it will not recieve interrupts during the kdump kernel boot, and this
hang will be the result.  The fix is to add this patch, whcih add an
early pci quirk check, to forcibly enable this bit in the httcfg
register.  This enables all cpus on a system to receive interrupts, and
allows kdump kernel bootup to procede normally.

Joerg Roedel 0440d4c00d x86 gart: rename symbols only used for the GART implementation
This patch renames the 4 symbols iommu_hole_init(), iommu_aperture,
iommu_aperture_allowed, iommu_aperture_disabled. All these symbols are only
used for the GART implementation of IOMMUs.

It adds and additional gart_ prefix to them.
