From b64e1c6139c5007b7773b0ce416ef9ea035e8724 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 23 Nov 2012 11:01:04 +0000 Subject: arm64: signal: return struct rt_sigframe from get_sigframe We only have one type of frame (rt_sigframe) for arm64, so just return that type directly and dispense with the framesize argument, which is presumably a hangover from code copied from arch/arm/.
