xen/blkback: simplify address translations
Cherry-pick and modified from 69d64727c42eecd47fdf82c15a54474d21a4012a
("blkback/blktap2: simplify address translations"):
"There are quite a number of places where e.g. page->va->page
translations happen.
Besides yielding smaller code (source and binary), a second goal is to
make it easier to determine where virtual addresses of pages allocated
through alloc_empty_pages_and_pagevec() are really used (in turn in
order to determine whether using highmem pages would be possible
there)."
The second goal is not the purpose of this patch - it is just to
make it easier to read the code.
linux-2.6-pvops:
* Stripped drivers/xen/gntdev/*
* Stripped drivers/xen/netback/*
[v2: Stripped blktap off]
