Subject: [merged] sched-remove-arch-specific-fpu_counter-from-task_struct.patch removed from -mm tree To: Vineet.Gupta1@xxxxxxxxxxxx,mingo@xxxxxxxxxx,paul.mundt@xxxxxxxxx,vgupta@xxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Wed, 13 Nov 2013 12:40:10 -0800 The patch titled Subject: sched: remove ARCH specific fpu_counter from task_struct has been removed from the -mm tree. Its filename was sched-remove-arch-specific-fpu_counter-from-task_struct.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vineet Gupta <Vineet.Gupta1@xxxxxxxxxxxx> Subject: 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.
