Merge branch 'regset.followup' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull regset updates from Al Viro:
 "Dead code removal, mostly.

  The only exception is a bit of cleanups on itanic (getting rid of
  redundant stack unwinds - each access_uarea() call does it and we call
  that 7 times in a row in ptrace_[sg]etregs(), *after* having done it
  ourselves in the caller; location where the user registers have been
  spilled won't change under us, and we can bloody well just call
  access_elf_reg() directly, giving it the unw_frame_info we'd
  calculated for our own purposes)"

* 'regset.followup' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  c6x: kill ELF_CORE_COPY_FPREGS
  whack-a-mole: USE_ELF_CORE_DUMP
  [ia64] ptrace_[sg]etregs(): use access_elf_reg() instead of access_uarea()
  [ia64] missed cleanups from switch to regset coredumps
  arm: kill dump_task_regs()
