mm/vmalloc.c: export unmap_kernel_range()
zsmalloc needs exported unmap_kernel_range for building as a module. See https://lkml.org/lkml/2013/1/18/487 I didn't send a patch to make unmap_kernel_range exportable at that time because zram was staging stuff and I thought VM function exporting for staging stuff makes no sense. Now zsmalloc was promoted. If we can't build zsmalloc as module, it means we can't build zram as module, either. Additionally, buddy map_vm_area is already exported so let's export unmap_kernel_range to help his buddy.
