x86 architecture fixes [with an UM fix included]:

Browse source 
- Don't apply va_align to hugetlb mappings on AMD F15h systems
    that have custom va_align.bits values (Laurent Wandrebeck)
 
  - Fix PMD teardown handling regression flagged by lockdep
    (Mikhail Gavrilov)
 
  - Hide ptrace header register offset macros behind __ASSEMBLER__ or
    __FRAME_OFFSETS, to fix user-space build errors that may trigger
    if they happen to shadow these short and generic macro names
    (Nick Desaulniers)
