acpi_map_lsapic() will allocate a logical CPU number and map it to
physical CPU id (such as APIC id) for the hot-added CPU, it will also
do some mapping for NUMA node id and etc, acpi_unmap_lsapic() will
do the reverse.

We can see that the name of the function is a little bit confusing and
arch dependent so rename them as acpi_(un)map_map() to make arch
agnostic and explicit.

That's acpi_(un)map_cpu() I guess?

ah, yes, typos, it should be acpi_(un)map_cpu(), my fault.
should I send another version?

Thanks

No, I can fix this up.

I've queued up the series for 3.19, thanks!
