From 597ff3a0f3ba6e471ce4dc93bf0b41abcebe9f8c Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Fri, 29 Aug 2014 16:08:02 +0100 Subject: [PATCH] arm64: Add brackets around user_stack_pointer() Commit 5f888a1d33 (ARM64: perf: support dwarf unwinding in compat mode) changes user_stack_pointer() to return the compat SP for 32-bit tasks but without brackets around the whole definition, with possible issues on the call sites (noticed with a subsequent fix for KSTK_ESP).
