Subject: x86: Remove SMP limitation in lapic_setup()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aaaa55751ab1e5a5cfa0962d604593a7e6f33ff6;p=project%2Fbcm63xx%2Fu-boot.git

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.
