    Subject[RFC v2][PATCH 27/35] m32r: use pte_offset_kernel() as base for pte_offset_map*()
    From
    Date

    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.
