Subject: [merged] lib-cpumask-make-cpumask_offstack-usable-without-debug-dependency.patch removed from -mm tree To: jwboyer@xxxxxxxxxx,hpa@xxxxxxxxx,jwboyer@xxxxxxxxxxxxxxxxx,mingo@xxxxxxxxxx,tglx@xxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Wed, 27 Nov 2013 12:26:35 -0800 The patch titled Subject: lib/cpumask: make CPUMASK_OFFSTACK usable without debug dependency has been removed from the -mm tree. Its filename was lib-cpumask-make-cpumask_offstack-usable-without-debug-dependency.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Josh Boyer <jwboyer@xxxxxxxxxx> Subject: lib/cpumask: make CPUMASK_OFFSTACK usable without debug dependency When CPUMASK_OFFSTACK was added in 2008, it was dependent upon DEBUG_PER_CPU_MAPS being enabled, or an architecture could select it. The debug dependency adds additional overhead that isn't required for operation of the feature, and we need CPUMASK_OFFSTACK to increase the NR_CPUS value beyond 512 on x86. We drop the current dependency and make sure SMP is set. Signed-off-by: Josh Boyer <jwboyer@xxxxxxxxxxxxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: "H.
