From 1bb50cad45f4a3fb9a339006d76efc50f70eed5b Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Wed, 23 Dec 2015 17:13:04 -0500 Subject: arch/tile: move user_exit() to early kernel entry sequence This ensures that we always notify context tracking that we have exited from user space no matter how we enter the kernel. It is similar to how arm64 handles context tracking, for example. This allows the removal of all the exception_enter() calls that were added in commit 49e4e15619cd ("tile: support CONTEXT_TRACKING and thus NOHZ_FULL").
