From bff2dc42bcafdd75c0296987747f782965d691a0 Mon Sep 17 00:00:00 2001 From: David Daney Date: Wed, 11 Sep 2013 14:23:26 -0700 Subject: smp.h: move !SMP version of on_each_cpu() out-of-line All of the other non-trivial !SMP versions of functions in smp.h are out-of-line in up.c. Move on_each_cpu() there as well. This allows us to get rid of the #include . The drawback is that this makes both the x86_64 and i386 defconfig !SMP kernels about 200 bytes larger each.
