[PATCH 0/6] LLVMLinux: Patches to enable the kernel to be compiled with clang/LLVM

From: Behan Webster <behanw@xxxxxxxxxxxxxxxxxx>

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).

Clang only supports global named registers for non-allocatable registers like
the stack pointer. By centralizing the definition of current_stack_pointer, the
use of named registers for ARM remains largely unchanged while working for both
gcc and clang.

Behan Webster (6):
arm: LLVMLinux: Add global named register current_stack_pointer for
arm: LLVMLinux: Use current_stack_pointer to calculate pt_regs address
arm: LLVMLinux: Use current_stack_pointer for return_address
arm: LLVMLinux: Use current_stack_pointer in save_stack_trace_tsk
arm: LLVMLinux: Calculate current_thread_info from
arm: LLVMLinux: Use current_stack_pointer in unwind_backtrace
