<nod> The only changes between before and after are that some of the
functions lose their static status, and some gain it; and a minor
indenting issue that I'll fix for the final patch series.

As far as makefiles go, both read_write.o and filemap.o are both obj-y
targets, so I think it's safe to make remap_range.o also an obj-y
target.  The fun part will be the careful Kconfig surgery to make
remap_range.o an optional build target, but that will come later.

<nod> Thanks. :)
