Krzysztof Helt found MTRR is not detected on k6-2
root cause:
we moved mtrr_bp_init() early for mtrr trimming,
and in early_detect we only read the CPU capability from cpuid,
so some cpu doesn't have that bit in cpuid.
So we need to add early_init_xxxx to preset those bit before mtrr_bp_init
for those earlier cpus.
this patch is for v2.6.27

Capitalize function call interrupts consistently.
All other descriptions in /proc/interrupts are capitalized except
for "function call interrupts". Capitalize it too for consistency.
While that's technically a published ABI I think the risk of anyone
relying on that text to stay the same is negligible.

I did some rebenchmarking with modern compilers and dropping
-funroll-loops makes the function consistently go faster by a few
percent. So drop that flag.

The last changes made the calibration loop 250ms long which is far
too much. Try to do that more clever.
Experiments have shown that using a 10ms delay for the PIT based calibration
gives us a good enough value. If we have a reference (HPET/PMTIMER) and the
result of the PIT and the reference is close enough, then we can break out of
the calibration loop on a match right away and use the reference value.
Otherwise we just loop 3 times and decide then, which value to take.
One caveat is that for virtualized environments the PIT calibration often does
not work at all and I found out that 10us is a bit too short as well for the
reference to give a sane result. The solution here is to make the last loop
longer when the first two PIT calibrations failed.

The Kbuild variable "targets" is supposed to be
configuration-independent and reflect "all possible targets". This is
required to make "make clean" work properly.
Therefore, move all manipulation of "targets" as well as custom rules
out of the x86-32 ifdef statement. Only leave inside the ifdefs the
things that are genuinely configuration-dependent.

The following patch (based on a patch from Stephen Gildea) fixes a
regression with the LCD brightness keys on Fujitsu P8010 laptops which was
observed with the 2.6.27-rc series (basically they stopped working due to
changes within the fujitsu-laptop and video modules). Please apply to
2.6.27-rc and acpi git.
A more complete solution for this laptop will be included in an upcoming
patch, hopefully for 2.6.28. In the meantime this restores most
functionality for P8010 users.

Currently the boiler plate code used by most ASoC codecs to provide a
placeholder for SPI access suggests making the selection of SPI a
compile time option which is suboptimal when trying to build kernels
supporting multiple systems. Change this template to suggest allowing
runtime selection instead.
Leave the drivers not yet converted to new style I2C access for now to
avoid collisions.

Commit 884525655d ("PCI: clean up resource
alignment management") changed the resource handling to mark how a
resource was aligned on a per-resource basis.
Thus, instead of looking at the resource number to determine whether it
was a bridge resource or a regular resource (they have different
alignment rules), we should just ask the resource for its alignment
directly.
The reason this broke only cardbus resources was that for the other
types of resources, the old way of deciding alignment actually still
happened to work. But CardBus bridge resources had been changed by
commit 934b7024f0 ("Fix cardbus resource
allocation") to look more like regular resources than PCI bridge
resources from an alignment handling standpoint.
