Oops, I overlooked the use of elf_core_copy_regs in kernel/kexec.c. It
is certainly safe and fine to reintroduce the old macro. Everything
removed in the "x86 user_regset cleanup" patch is purely removing code
and it doesn't hurt to have it back (it's just all unused except for this
kexec nit).

Hi Ingo,
on recent x86.git kernel fails to kdump with following BUG.
SysRq : Trigger a crashdump
[ cut here ]
kernel BUG at include/linux/elfcore.h:105!
invalid opcode: [1] PREEMPT SMP
In crash_save_cpu(), elf_core_copy_regs() is called and
ELF_CORE_COPY_REGS macro
