Ralf,
Please try and push it ASAP, with 4.5 if possible. This should be an
obviously correct internal API consistency fix, along the lines of the
recent `ioremap_uc' addition. NB, there's a fallback `ioremap_cache'
implementation in kernel/memremap.c redirecting to plain `ioremap', but I
think we should simply do the right thing rather than relying on that
code.
Thanks,
Maciej
