From aaaa55751ab1e5a5cfa0962d604593a7e6f33ff6 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 22 May 2016 01:45:32 -0700 Subject: [PATCH] x86: Remove SMP limitation in lapic_setup() At present LAPIC is enabled and configured as virtual wire mode in lapic_setup() only when CONFIG_SMP is on. This limitation is however not necessary as for uniprocessor this is still needed.
