Hi all,

this series replaces various open coded kmaps of bio_vecs with higher
level helpers that use kmap_local_page underneath. It does not touch
other kmap calls in these drivers even if those should probably also
be switched to use kmap_local eventually.

Changes since v1:
- fix missing switches to kunmap_local
