Subject: 6ea8c546f3655 breaks thermal management on thinkpad x60 and t40p

Hi!

Bisection was not fun, but I've got the result:

# first bad commit: [6ea8c546f3655a81f82672f24b66dad6095bdd07] ACPICA:
FADT support cleanup

I've reverted the patch on top of 4.9-rc4, and thermal management now works.

More details are in https://bugzilla.kernel.org/show_bug.cgi?id=187311

As this breaks thermal management on both thinkpad X60 and T40p, can
I ask for a revert?

If you have other ideas, I can test them, but as this is just a
cleanup, it can wait for 4.10...

Thanks,
									Pavel
