Merge branch 'x86-cpufeature-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpufeature updates from Ingo Molnar:
"This tree includes the following changes:
- Introduce DISABLED_MASK to list disabled CPU features, to simplify
CPU feature handling and avoid excessive #ifdefs
- Remove the lightly used cpu_has_pae() primitive"
* 'x86-cpufeature-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Add more disabled features
x86: Introduce disabled-features
x86: Axe the lightly-used cpu_has_pae
