From c375f15a434db1867cb004bafba92aba739e4e39 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 12 Nov 2013 15:08:46 -0800 Subject: x86: move fpu_counter into ARCH specific thread_struct Only a couple of arches (sh/x86) use fpu_counter in task_struct so it can be moved out into ARCH specific thread_struct, reducing the size of task_struct for other arches.
