Here are seven more patches for things I found to clean up.
This was based on top of Christoph's seven patches:
"hmm_range_fault related fixes and legacy API removal v3".
I assume this will go into Jason's tree since there will likely be
more HMM changes in this cycle.

Changes from v1 to v2:

Added AMD GPU to hmm_update removal.
Added 2 patches from Christoph.
Added 2 patches as a result of Jason's suggestions.

Christoph Hellwig (2):
  mm/hmm: replace the block argument to hmm_range_fault with a flags
    value
  mm: merge hmm_range_snapshot into hmm_range_fault

Ralph Campbell (5):
  mm/hmm: replace hmm_update with mmu_notifier_range
  mm/hmm: a few more C style and comment clean ups
  mm/hmm: make full use of walk_page_range()
  mm/hmm: remove hugetlbfs check in hmm_vma_walk_pmd
  mm/hmm: remove hmm_range vma

For all of these:

Reviewed-by: Jason Gunthorpe <jgg@mellanox.com>

I've applied this to hmm.git, excluding:

>   mm/hmm: make full use of walk_page_range()

Pending further discussion.

Based on last cycle I've decided to move good patches into linux-next
earlier and rely on some rebase if needed. This is to help Andrew's
workflow.

So, if there are more tags/etc please continue to send them, I will
sort it..

Thanks,
Jason
