remove most callers of write_one_page v4
Hi all,
this series removes most users of the write_one_page API. These helpers
internally call ->writepage which we are gradually removing from the
kernel.
Changes since v3:
- drop all patches merged in v6.3-rc1
- re-add the jfs patch
Changes since v2:
- more minix error handling fixes
Changes since v1:
- drop the btrfs changes (queue up in the btrfs tree)
- drop the finaly move to

[PATCH v1 0/2] nouveau/svm: fix + cleanup for nouveau_atomic_range_fault()
One fix and a minor cleanup.
Only compile-tested due to lack of HW, so I'd be happy if someone with
access to HW could test. But not sure how easy this is to trigger. Likely
some concurrent MADV_DONTNEED on the PTE we just converted might be able
to trigger it.
