Some architectures use pte_offset_map() as a basis for
pte_offset_kernel(). Others do the inverse.
Although arbitrary, Using pte_offset_kernel() as the base
seems a wee bit more popular and it also fits in well
with the way I'm breaking out the headers.
Instead of coding the same implementation twice, this
makes pte_offset_map{,_nested}() call pte_offset_kernel()
directly.
