+Subject: include/linux/smp.h:on_each_cpu(): switch back to a macro
+
+From: Andrew Morton <akpm@linux-foundation.org>
+
+commit c846ef7deba2d4f75138cf6a4b137b7e0e7659af upstream.
+
+Commit f21afc25f9ed ("smp.h: Use local_irq_{save,restore}() in !SMP
+version of on_each_cpu()") converted on_each_cpu() to a C function.
+
+This required inclusion of irqflags.h, which broke ia64 and mn10300 (at
+least) due to header ordering hell.
+
+Switch on_each_cpu() back to a macro to fix this.
