Cover letter [patch 0/5] mm: improve remapping of vmalloc regions

Hi,

I'd like some feedback about this patchset -- whether it is the right design, and the implementation (e.g. people might dislike patch 4).

vm_insert_page and remap_pfn_range loops are really clever, bit probably asking a bit too much of most drivers. I was able to get rid of most of them without too much trouble.

Not tested, because I don't have any of the hardware, but it seems compiles OK.

Nick
