    Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
    
    Pull x86 PTI preparatory patches from Thomas Gleixner:
     "Todays Advent calendar window contains twentyfour easy to digest
      patches. The original plan was to have twenty three matching the date,
      but a late fixup made that moot.
    
       - Move the cpu_entry_area mapping out of the fixmap into a separate
         address space. That's necessary because the fixmap becomes too big
         with NRCPUS=8192 and this caused already subtle and hard to
         diagnose failures.
    
         The top most patch is fresh from today and cures a brain slip of
         that tall grumpy german greybeard, who ignored the intricacies of
         32bit wraparounds.
    
       - Limit the number of CPUs on 32bit to 64. That's insane big already,
         but at least it's small enough to prevent address space issues with
         the cpu_entry_area map, which have been observed and debugged with
         the fixmap code
    
       - A few TLB flush fixes in various places plus documentation which of
         the TLB functions should be used for what.
    
       - Rename the SYSENTER stack to CPU_ENTRY_AREA stack as it is used for
         more than sysenter now and keeping the name makes backtraces
         confusing.
    
       - Prevent LDT inheritance on exec() by moving it to arch_dup_mmap(),
         which is only invoked on fork().
    
       - Make vysycall more robust.
    
       - A few fixes and cleanups of the debug_pagetables code. Check
         PAGE_PRESENT instead of checking the PTE for 0 and a cleanup of the
         C89 initialization of the address hint array which already was out
         of sync with the index enums.
    
       - Move the ESPFIX init to a different place to prepare for PTI.
    
       - Several code moves with no functional change to make PTI
         integration simpler and header files less convoluted.
    
       - Documentation fixes and clarifications"
