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"
