3.13.11.5 -stable review patch. If anyone has any objections, please let me know.
------------------
From: ChiaHao <andy.jhshiu@gmail.com>
commit 3906c2b53cd23c2ae03e6ce41432c8e7f0a3cbbb upstream.
The value of ESR has been stored into x1, and should be directly pass to do_sp_pc_abort function, "MOV x1, x25" is an extra operation and do_sp_pc_abort will get the wrong value of ESR.
