From 55b2662ec665cc8b592809a011fe807b05370ab8 Mon Sep 17 00:00:00 2001 From: Stafford Horne Date: Tue, 4 Aug 2020 10:41:54 +0900 Subject: openrisc: uaccess: Add user address space check to access_ok Now that __user annotations are fixed for openrisc uaccess api's we can add checking to the access_ok macro. This patch adds the __chk_user_ptr check, on normal builds the added check is a nop.
