x86 architecture fixes [with an UM fix included]:

 - 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)

 Thanks,

	Ingo
