Date: Tue, 22 Jul 2014 15:21:38 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: ChiaHao <andy.jhshiu@...il.com>, Catalin Marinas <catalin.marinas@....com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 087/116] arm64: Bug fix in stack alignment exception 3.8.13.27 -stable review patch. If anyone has any objections, please let me know. ------------------ From: ChiaHao <andy.jhshiu@...il.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.
