Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A couple of fixes and updates related to x86:
- Fix the W+X check regression on XEN
- The real fix for the low identity map trainwreck
- Probe legacy PIC early instead of unconditionally allocating legacy
irqs
- Add cpu verification to long mode entry
- Adjust the cache topology to AMD Fam17H systems
- Let Merrifield use the TSC across S3"
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/cpu: Call verify_cpu() after having entered long mode too
x86/setup: Fix low identity map for >= 2GB kernel range
x86/mm: Skip the hypervisor range when walking PGD
x86/AMD: Fix last level cache topology for AMD Fam17h systems
x86/irq: Probe for PIC presence before allocating descs for legacy IRQs
x86/cpu/intel: Enable X86_FEATURE_NONSTOP_TSC_S3 for Merrifield
