Subject: [PATCH 0/8] x86: vdso and vsyscall round 1 for 3.17

This is mostly cleanups.  Patch 1 fixes a minor bug; it might make sense
to backport it.

Patch 3 removes the vsyscall mapping when vsyscall=none.

Patches 4 and 5 remove everything except gtod from the vvar page; the
other vvars weren't really necessary.

Patch 2, 6, 7, and 8 are pure cleanups.

This is based on tip/x86/vdso.

Andy Lutomirski (8):
  x86_64,vsyscall: Fix warn_bad_vsyscall log output
  x86_64,vsyscall: Move all of the gate_area code to vsyscall_64.c
  x86_64,vsyscall: Turn vsyscalls all the way off when vsyscall=none
  x86_64,vdso: Remove jiffies from the vvar page
  x86,vdso: Replace vgetcpu_mode with static_cpu_has
  x86_64: Move getcpu code from vsyscall_64.c to vdso/vma.c
  x86_64,vsyscall: Rewrite comment and clean up headers in vsyscall code
  x86_64,vdso: Clean up vgetcpu init and merge the vdso initcalls
