From 27f69e68a5e534412faebc53a4e04acc9ce7fd7e Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 12 Nov 2013 15:08:47 -0800 Subject: [PATCH] sched: remove ARCH specific fpu_counter from task_struct fpu_counter in task_struct was used only by sh/x86. Both of these now carry it in ARCH specific thread_struct, hence this can now be removed from generic task_struct, shrinking it slightly for other arches.
