From e8fc96ed3603924e7aa09fd5e4dbd289b7e69907 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Thu, 4 Sep 2008 09:56:10 -0700 Subject: [PATCH] dyn_array: don't break compiling for !CONFIG_SMP Impact: build failure on uniprocessor When compiling for !CONFIG_SMP, per_cpu_alloc_dyn_array() would fail to compile, since it uses per_cpu_offset, which is not defined for uniprocessor builds. Hence, do not compile per_cpu_alloc_dyn_array() for !CONFIG_SMP. Attempting to call this function in a uniprocessor configuration would be simply wrong in the first place. Signed-off-by: H.
