This patch set moves from using locally defined named registers to access the
stack pointer to using a globally defined named register. This allows the code
to work both with gcc and clang.

The LLVMLinux project aims to fully build the Linux kernel using both gcc and
clang (the C front end for the LLVM compiler infrastructure project).

Behan Webster (4):
  arm64: LLVMLinux: Add current_stack_pointer() for arm64
  arm64: LLVMLinux: Use current_stack_pointer in save_stack_trace_tsk
  arm64: LLVMLinux: Calculate current_thread_info from
    current_stack_pointer
  arm64: LLVMLinux: Use current_stack_pointer in kernel/traps.c

Please can you send a new series after the merge window?

Given that the ARM64 KVM guys are still actively breaking -next, and
this is considerably smaller and lower risk than that, I think you can
take it for 3.17?
