[GIT] IPS driver updates

Hi Linus,

I'd prefer not to have something this size this late in the window, but
I've finally got hold of IPS-capable hardware myself and found that the
driver as is basically doesn't work - it's trivial to get it to start
complaining about thermal limits when the machine is under load. Jesse's
provided some patches that disable some of the functionality without
turning off the whole driver, which should still give most of the
performance boost. There's also a couple of patches from Minskey to fix
one or two register size issues and a potential NULL dereference.

The following changes since commit 3c06806e690885ce978ef180c8f8b6f8c17fb4b4:

Merge branch 'merge-powerpc' of git://git.secretlab.ca/git/linux-2.6 (2010-10-04 11:45:35 -0700)

are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86.git for_linus

Andy Whitcroft (1):
intel_ips -- ensure we do not enable gpu turbo mode without driver linkage

Jesse Barnes (4):
IPS driver: don't toggle CPU turbo on unsupported CPUs
IPS driver: verify BIOS provided limits
IPS driver: apply BIOS provided CPU limit if different from default
IPS driver: disable CPU turbo

Matthew Garrett (1):
IPS driver: Fix limit clamping when reducing CPU power

Tim Gardner (1):
intel_ips: Print MCP limit exceeded values.

minskey guo (4):
seqno mask of THM_ITV register is 16bit
old_cpu_power is wrongly divided by 65535 in ips_monitor()
Release symbol on error-handling path of ips_get_i915_syms()
NULL pointer might be used in ips_monitor()
