This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

mlx4_get_umem_mr() uses provided user pointers for vma lookups, which can
only by done with untagged pointers.

Untag user pointers in this function.

This patch also needs an ack from the infiniband maintainers (Jason).

Hi Jason,

Could you take a look and give your acked-by?

Oh, I think I did this a long time ago. Still looks OK.

Hm, maybe that was we who lost it. Thanks!

You will send it?

I will resend the patchset once the merge window is closed, if that's
what you mean.

No.. I mean who send it to Linus's tree? ie do you want me to take
this patch into rdma?

I think the plan was to merge the whole series through the mm tree.
But I don't mind if you want to take this patch into your tree. It's
just that this patch doesn't make much sense without the rest of the
series.

Generally I prefer if subsystem changes stay in subsystem trees. If
the patch is good standalone, and the untag API has already been
merged, this is a better strategy.

Jason
