From: Catalin Marinas Date: Sun, 6 Apr 2014 22:04:12 +0000 (+0100) Subject: arm64: Provide read/write fault information in compat signal handlers X-Git-Tag: omap-for-v3.16/fixes-against-rc1~91^2~10^2~44 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9141300a5884b57cea6d32c4e3fd16a337cfc99a;p=pandora-kernel.git arm64: Provide read/write fault information in compat signal handlers For AArch32, bit 11 (WnR) of the FSR/ESR register is set when the fault was caused by a write access and applications like Qemu rely on such information being provided in sigcontext. This patch introduces the ESR_EL1 tracking for the arm64 kernel faults and sets bit 11 accordingly in compat sigcontext. Signed-off-by: Catalin Marinas --- Reading git-diff-tree failed
