Subject: x86: move {un}map_cpu_to_logical_apicid to smpboot.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7cc3959ecd830796231f50bf5e42dc018b3694f2;p=openwrt%2Fstaging%2Fblogic.git

x86: move {un}map_cpu_to_logical_apicid to smpboot.c

Move map_cpu_to_logical_apicid() and unmap_cpu_to_logical_apicid()
to smpboot.c. They take together all the bunch of static functions
they rely upon
