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 <catalin.marinas@arm.com>
