Merge branch 'x86-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull x86 fixes from Thomas Gleixner:
 "A set of small fixes for x86:

   - fix locking in RDT to prevent memory leaks and freeing in use
     memory

   - prevent setting invalid values for vdso32_enabled which cause
     inconsistencies for user space resulting in application crashes.

   - plug a race in the vdso32 code between fork and sysctl which causes
     inconsistencies for user space resulting in application crashes.

   - make MPX signal delivery work in compat mode

   - make the dmesg output of traps and faults readable again"
