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

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.
