* commit 'remotes/tip/x86/paravirt': (175 commits)
  xen: use direct ops on 64-bit
  xen: make direct versions of irq_enable/disable/save/restore to common code
  xen: setup percpu data pointers
  xen: fix 32-bit build resulting from mmu move
  x86/paravirt: return full 64-bit result
  x86, percpu: fix kexec with vmlinux
  x86/vmi: fix interrupt enable/disable/save/restore calling convention.
  x86/paravirt: don't restore second return reg
  xen: setup percpu data pointers
  x86: split loading percpu segments from loading gdt
  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
  xen: move remaining mmu-related stuff into mmu.c
