In a few days, but wanted to hear back from either Jeremy or Becky
first about how well they actually work in their usecases.

Well, you don't need to wait, I think.

All Jeremy and Becky need is adding highmem support to swiotlb. How we
support it doesn't matter. We can choose better one.

We all (including Jeremy) agreed that Becky's physical address scheme is
better (simpler) than Jeremy's struct page and offset scheme. Surely,
Becky's scheme works for Xen and him (Jeremy said that he tested it
lightly).


Jeremy said, when he submitted this series, shortly before Christmas:

Here's a work in progress series [...]

Quick testing showed no problems, but I haven't had the chance to do
anything extensive.

Jeremy, did you have a chance to do more testing with the current
tip/master bits on Xen, so that we can push it to Linus?


I'm going to be on vacation until the 12th, so I won't have a chance to
do anything until then (perhaps Ian will have a chance to poke at them
before then). I'm expecting Becky's patches to work as-is, or if not,
be easily fixed with a couple of small bugfix patches. So I say go
ahead if they work for everyone else.

Only just got out from under my pile of vacation backlog...

They don't quite work with Xen (at least the version in Jeremy's patch
queue doesn't) but I agree that it should be possible to make it work
and that there's no point in holding back just for Xen.

I'm also back (temporarily), and they're not quite going to work for powerpc, either, but it shouldn't be anything major to fix, and since it didn't work on powerpc before, that shouldn't hold anything up. I'm working on getting things working for me again now. Unfortunately, it now looks like I'm going to have to be out of the office next week, but I expect to get something out as soon as I'm back, if I don't get a chance to fix it today.

Jeremy, many thanks for your work merging my patches in with your series!

Cheers,
Becky
