    Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 918d80a1
    Linus Torvalds 提交于
    Pull x86 cpu handling changes from Ingo Molnar:
     "Bigger changes:
    
       - Intel CPU hardware-enablement: new vector instructions support
         (AVX-512), by Fenghua Yu.
    
       - Support the clflushopt instruction and use it in appropriate
         places.  clflushopt is similar to clflush but with more relaxed
         ordering, by Ross Zwisler.
    
       - MSR accessor cleanups, by Borislav Petkov.
    
       - 'forcepae' boot flag for those who have way too much time to spend
         on way too old Pentium-M systems and want to live way too
         dangerously, by Chris Bainbridge"
