As Eric said,
 "what we need to do is move the variable vmcoreinfo_note out of the
  kernel's .bss section. And modify the code to regenerate and keep this
  information in something like the control page.

  Definitely something like this needs a page all to itself, and ideally
  far away from any other kernel data structures. I clearly was not
  watching closely the data someone decided to keep this silly thing in
  the kernel's .bss section."

This patch allocates extra pages for these vmcoreinfo_XXX variables, one
advantage is that it enhances some safety of vmcoreinfo, because
vmcoreinfo now is kept far away from other kernel data structures.

The VDSO symbols can't be linked into built-in.o when building with
thin archives, so change this to linking a new object file that is
included into the built-in.o.

All the files listed in "extra-y" are generated according to the
dependency.  They are still needed in "targets" to include .*.cmd
for incremental building.

Pull namespace updates from Eric Biederman:
 "This is a set of small fixes that were mostly stumbled over during
  more significant development. This proc fix and the fix to
  posix-timers are the most significant of the lot.

  There is a lot of good development going on but unfortunately it
  didn't quite make the merge window"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  proc: Fix unbalanced hard link numbers
  signal: Make kill_proc_info static
  rlimit: Properly call security_task_setrlimit
  signal: Remove unused definition of sig_user_definied
  ia64: Remove unused IA64_TASK_SIGHAND_OFFSET and IA64_SIGHAND_SIGLOCK_OFFSET
  ipc: Remove unused declaration of recompute_msgmni
  posix-timers: Correct sanity check in posix_cpu_nsleep
  sysctl: Remove dead register_sysctl_root
