So this is one huge patch touching several arches with potential to cause
conflicts when merged. Can u divy them up and then the maintainers can simply
merge them individually given there is no common dependency !

Looks good. I can take the asm-generic portion when you split it up, and
I can also help you merge the remaining patches in case some of
the arch maintainers fail to pick them up. I think all five of them
are actively maintained though, so the patches should just go through
the respective architecture trees.

Or we just ack the patch and have it go through one tree, which I think
is the most sensible. I can't imagine that there would be any major
conflicts here, surely no one is constantly changing their asm/page.h ?

Yes, good point, there is really very little potential for conflicts
here. I've applied it into my asm-generic tree for now, but will
revert it if we get regressions or NAKs.
For some reason, the patch was whitespace broken, but I managed to
extract it from the attachment.

Thank all of you for your work. At present, it is also queued into akpm
tree, and will be seen in the next-tree soon.
For me, this patch looks cross multi-archs, but it is still very simple.
I found this patch only because I am learning mm sub-system.
I am reading mm headers to be familiar with them, so can understand mm
globally based on code. These headers are common sense for most mm/arch
members, but for me (almost a newbie), they are not (need be familiar).
Thanks.

* [PATCH] include: asm-generic: page.h: Remove useless get_user_page and free_user_page

Thank all of you for your work. At present, it is also queued into akpm
tree, and will be seen in the next-tree soon.
For me, this patch looks cross multi-archs, but it is still very simple.
I found this patch only because I am learning mm sub-system.
I am reading mm headers to be familiar with them, so can understand mm
globally based on code. These headers are common sense for most mm/arch
members, but for me (almost a newbie), they are not (need be familiar).
Thanks.

Compile and run tested on m68k (MMU and noMMU) targets.
No problems found. So for those parts:
