Wrapper Helper Help Please
...all. I''m hoping this is a simple one that someone can put me right
on.
I have a view that ''wraps'' some div''s around a Page Header and Page
Content, for formatting reasons:
<div id="LHS">
<div class="Page">
<div class="PageHeader">
''Header Here''
</div>
<div class="PageContent">
''Content Here''
</div>
</div>
</div>
I use this ''wrapper'' a lot, so I thought I''d put it into a helper,
thus:

[PATCH v3 0/6] mm/hmm/nouveau: add THP migration to migrate_vma_*
This series adds support for transparent huge page migration to
migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers.
Earlier versions were posted previously [1] and [2].
The patches apply cleanly to the linux-mm 5.10.0-rc2 tree. There are a
lot of other THP patches being posted. I don't think there are any
semantic conflicts but there may be some merge conflicts depending on

[PATCH v2 0/7] mm/hmm/nouveau: add THP migration to migrate_vma_*
This series adds support for transparent huge page migration to
migrate_vma_*() and adds nouveau SVM and HMM selftests as consumers.
An earlier version was posted previously [1]. This version now
supports splitting a THP midway in the migration process which
led to a number of changes.
The patches apply cleanly to the current linux-mm tree. Since there
are a couple of patches in linux-mm from Dan

[PATCH 00/16] mm/hmm/nouveau: THP mapping and migration
These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go
into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM
self tests. Patch 7-8 prepare nouveau for the meat of this series which
adds support and testing for compound page mapping of system memory
(patches 9-11) and compound page migration to device private memory
(patches 12-16). Since these changes are split
