Merge commit 'remotes/tip/x86/paravirt' into x86/untangle2
* 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 ...
