'misc', 'suspend', 'thermal', 'thinkpad' and 'tsc' into release

TSC is used even on machines when CONFIG_X86_TSC is not set (X86_TSC
means _require_ TSC), but it is not properly disabled when it is
unusable, because ACPI code understood the config switch as "may use
TSC".
This actually fixes suspend problems on my x60.

A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the
existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the
X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is
tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is
set).
Add an attribute to report this information, "hotkey_tablet_mode". This
attribute has poll()/select() support, and can be used along with EV_SW
SW_TABLET_MODE to hook userspace to tablet events.

Issue EV_SW SW_TABLET_MODE events for HKEY events 0x5009 and 0x500A on the
X41t/X60t/X61t. As usual, we suppress the HKEY events on the netlink
interface to avoid sending duplicate events to userspace.

The video output port control feature is not very useful on many ThinkPads
(especially when a X server is running), and lately userspace is getting
better and better at it, so it makes sense to allow users to stripe out the
thinkpad-acpi video feature from their kernels and save at least 2KB.

This patch implements libata.force module parameter which can
selectively override ATA port, link and device configurations
including cable type, SATA PHY SPD limit, transfer mode and NCQ.
For example, you can say "use 1.5Gbps for all fan-out ports attached
to the second port but allow 3.0Gbps for the PMP device itself, oh,
the device attached to the third fan-out port chokes on NCQ and
shouldn't go over UDMA4" by the following.

Noted by various people (Sam, Jeff, Roland..)
Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the
xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the
tree as a empty file, and would cause git to correctly complain about a
tracked file being removed after a "make distclean" (which removes empty
files as garbage).
And the asm-x86/desc_64.h file was supposed to be removed by commit
c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around
containing just a single newline.
Get rid of them both properly.

Several AGP drivers right now use ioremap_nocache() on kernel ram in order
to turn a page of regular memory uncached.
There are two problems with this:
1) This is a total nightmare for the ioremap() implementation to keep
various mappings of the same page coherent.
2) It's a total nightmare for the AGP code since it adds a ton of
complexity in terms of keeping track of 2 different pointers to
the same thing, in terms of error handling etc etc.
This patch fixes this by making the AGP drivers use the new
set_memory_XX APIs instead.
Note: amd-k7-agp.c is built on Alpha too, and generic.c is built
on ia64 as well, which do not yet have the set_memory_*() APIs,
so for them some we have a few ugly #ifdefs - hopefully they'll
be fixed soon.

In hibernate, we may end up calling the VGA save regs function twice, so we need to make sure it's idempotent. That means leaving ARX in index mode after the first save operation. Fixes hibernate on 965.

Failing to preserve the MI_ARB_STATE register was causing FIFO underruns on
the VGA output on my HP 2510p after resume.

On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume. So restore them unconditionally along with actually restoring pipe B's palette correctly.

On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause
the kernel to disable the interrupt or vblank events to happen at the
wrong time. So save/restore them properly.
