  x86: pass in cpu number to switch_to_new_gdt()
  x86: UV fix uv_flush_send_and_wait()
  x86/paravirt: fix missing callee-save call on pud_val
  x86/paravirt: use callee-saved convention for pte_val/make_pte/etc
  x86/paravirt: implement PVOP_CALL macros for callee-save functions
  x86/paravirt: add register-saving thunks to reduce caller register pressure
  x86/paravirt: selectively save/restore regs around pvops calls
  x86: fix paravirt clobber in entry_64.S
  x86/pvops: add a paravirt_ident functions to allow special patching
