OK. But I'd still like Russell to indicate whether he agrees with all
of this, i.e., wire up memremap() to perform MT_MEMORY_RW mappings in
the vmalloc area of memory regions that may be potentially be covered
by highmem as well.

I'm happy to go that way: go back to ioremap_cached() for pxa2xx-flash
and switch memremap() to MT_MEMORY_RW - I think that makes total sense.

I think it is worth putting a comment against ioremap_cached() saying
that it's for pxa2xx-flash.c though, and deprecated for new uses.

OK, I will respin the series, and replace patch #1 with two patches that

a) reintroduce ioremap_cached() (with the comment, as you say)
b) move pxa2xx-flash from memremap to ioremap_cached()
