From 8c1fc5abdccfb36102fa9647084eeb8c70e32562 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 31 Jan 2019 10:08:54 +0000 Subject: powerpc: Rename THREAD_INFO to TASK_STACK This patch renames THREAD_INFO to TASK_STACK, because it is in fact the offset of the pointer to the stack in task_struct so this pointer will not be impacted by the move of THREAD_INFO. Also make it available on 64-bit, as we'll need it there when we activate THREAD_INFO_IN_TASK.
