Merge branch 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cleanups from Ingo Molnar: "The main changes in this cycle were: - code patching and cpu_has cleanups (Borislav Petkov) - paravirt cleanups (Juergen Gross) - TSC cleanup (Thomas Gleixner) - ptrace cleanup (Chen Gang)" * 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arch/x86/kernel/ptrace.c: Remove unused arg_offs_table x86/mm: Align macro defines x86/cpu: Provide a config option to disable static_cpu_has x86/cpufeature: Remove unused and seldomly used cpu_has_xx macros x86/cpufeature: Cleanup get_cpu_cap() x86/cpufeature: Move some of the scattered feature bits to x86_capability x86/paravirt: Remove paravirt ops pmd_update[_defer] and pte_update_defer x86/paravirt: Remove unused pv_apic_ops structure x86/tsc: Remove unused tsc_pre_init() hook x86: Remove unused function cpu_has_ht_siblings() x86/paravirt: Kill some unused patching functions
