Pull MM updates from Andrew Morton:
"Most of the MM queue. A few things are still pending.

Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.

Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.

Summary:

- The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
Lin, Yang Shi, Anshuman Khandual and Mike Rapoport

- Some kmemleak fixes from Patrick Wang and Waiman Long

- DAMON updates from SeongJae Park

- memcg debug/visibility work from Roman Gushchin

- vmalloc speedup from Uladzislau Rezki

- more folio conversion work from Matthew Wilcox

- enhancements for coherent device memory mapping from Alex Sierra

- addition of shared pages tracking and CoW support for fsdax, from
Shiyang Ruan

- hugetlb optimizations from Mike Kravetz

- Mel Gorman has contributed some pagealloc changes to improve
latency and realtime behaviour.

- mprotect soft-dirty checking has been improved by Peter Xu

- Many other singleton patches all over the place"

mm/cma: change cma mutex to irq safe spinlock

Patch series "make hugetlb put_page safe for all calling contexts", v5.

This effort is the result a recent bug report [1]. Syzbot found a
potential deadlock in the hugetlb put_page/free_huge_page_path. WARNING:
SOFTIRQ-safe -> SOFTIRQ-unsafe lock order detected Since the
free_huge_page_path already has code to 'hand off' page free requests to a
workqueue, a suggestion was proposed to make the in_irq() detection
accurate by always enabling PREEMPT_COUNT [2]. The outcome of that
discussion was that the hugetlb put_page path (free_huge_page) path should
be properly fixed and safe for all calling contexts.

[1] https://lore.kernel.org/linux-mm/000000000000f1c03b05bc43aadc@google.com/
[2] http://lkml.kernel.org/r/20210311021321.127500-1-mike.kravetz@oracle.com

This patch (of 8):

cma_release is currently a sleepable operatation because the bitmap
manipulation is protected by cma->lock mutex. Hugetlb code which relies
on cma_release for CMA backed (giga) hugetlb pages, however, needs to be
irq safe.

The lock doesn't protect any sleepable operation so it can be changed to a
(irq aware) spin lock. The bitmap processing should be quite fast in
typical case but if cma sizes grow to TB then we will likely need to
replace the lock by a more optimized bitmap implementation.
