4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dave Hansen <dave.hansen@linux.intel.com>

commit 6e17cb9c2d5efd8fcc3934e983733302b9912ff8 upstream

We had a new CPUID "NCAPINT" word added, but the REQUIRED_MASK and
DISABLED_MASK macros did not get updated.  Update them.

None of the features was needed in these masks, so there was no
harm, but we should keep them updated anyway.
