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.

I want to put into powerpc-next patches relying into that, so if the
patch is ok with you guys, can I stick it in powerpc.git ?
