Hi Jens,

this series adds a bvec_virt helper to return the virtual address of the
data in bvec to replace the open coded calculation, and as a reminder
that generall bio/bvec data can be in high memory unless it is caller
controller or in an architecture specific driver where highmem is
impossible.
