vmalloc: add __get_vm_area_caller()
We have get_vm_area_caller() and __get_vm_area() but not
__get_vm_area_caller()
On powerpc, I use __get_vm_area() to separate the ranges of addresses
given to vmalloc vs. ioremap (various good reasons for that) so in order
to be able to implement the new caller tracking in /proc/vmallocinfo, I
need a "_caller" variant of it.
(akpm: needed for ongoing powerpc development, so merge it early)
