Date: Fri, 18 Jul 2014 14:11:49 +0200 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, ChiaHao <andy.jhshiu@...il.com>, Catalin Marinas <catalin.marinas@....com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 104/170] arm64: Bug fix in stack alignment exception From: ChiaHao <andy.jhshiu@...il.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== 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.
