[RFC][PATCH 0/3] xip: no struct pages -- summary

This short series extendeds one of Nick Piggins patches for the XIP
overhaul that we've been kicking around.  I'm just hoping to get the
API changes reviewed now.  I haven't tested this, just compiled what I
can.

So what I'm doing here is swapping out get_xip_page() for
get_xip_mem().  The get_xip_mem() API gives us a kaddr and a pfn.  I
thought it worked best to force this kaddr and pfn down through the
block dev's direct_access() API.  I'm really unsure if I understand
whether I got the device specific implementations of the new
direct_access() right.

For those interested I'll be updating my git tree at
git.infradead.org/users/jehulber/axfs.git with an updated patch set
Monday.
