From: Behan Webster <behanw@converseincode.com>
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 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 current_stack_pointer arm: LLVMLinux: Use current_stack_pointer in unwind_backtrace
