From 051168df528fe4456d63f5f65b041c147c26fe97 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Tue, 3 Sep 2013 14:45:52 -0400 Subject: tile: don't assume user privilege is zero Technically, user privilege is anything less than kernel privilege. We modify the existing user_mode() macro to have this semantic (and use it in a couple of places it wasn't being used before), and add an IS_KERNEL_EX1() macro to the assembly code as well.
