    Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
    
    Pull x86 fixes from Thomas Gleixner:
     "A small set of fixes for x86:
    
       - Add missing instruction suffixes to assembly code so it can be
         compiled by newer GAS versions without warnings.
    
       - Switch refcount WARN exceptions to UD2 as we did in general
    
       - Make the reboot on Intel Edison platforms work
    
       - A small documentation update so text and sample command match"
