Changes since v7 [1]:
* rebase on the mid-merge-window state of the tree to pick up new mmap
implementations.
* expand the mmap operation handler conversion beyond 'struct
file_operations' to include, 'struct etnaviv_gem_ops', 'struct
dma_buf_ops', 'struct drm_driver', 'struct fb_ops', and 'struct
v4l2_file_operations'
* pass 'map_flags' through to all sub-handlers (Christoph)
* rework the mmap flag validation mechanism to the MAP_SHARED_VALIDATE
scheme (Linus)

In order to safely add new mmap flags we want all mmap implementations
to both opt-in to the new flags they support and have the ability to
reject flags on a per-mmap-call basis. An alternative to all the churn
in patch1 is to add a new ->map_flags attribute to 'struct
vma_area_struct', but that bloats the runtime state everywhere for the
few mmap implementations that will care about new flags. Of course, this
also assumes that there are no general objections to the plans to
eventually add MAP_SYNC and/or MAP_DIRECT for DAX mappings [2].
The current request is to merge the final version of patch1 next week,
right before -rc1, i.e. before new ->mmap() handlers start landing in
-next. Given that the drm, media, and sound pull requests are already
merged only some small tweaks are expected from here on out. Patch2 is
included for review, but it can wait and go in with the new MAP_ flags.
Please holler if anything does not look right.

We are running running short of vma->vm_flags. We can avoid needing a
new VM_* flag in some cases if the original @flags submitted to mmap(2)
is made available to the ->mmap() 'struct file_operations'
implementation. For example, the proposed addition of MAP_DIRECT can be
implemented without taking up a new vm_flags bit. Another motivation to
avoid vm_flags is that they appear in /proc/$pid/smaps, and we have seen
software that tries to dangerously (TOCTOU) read smaps to infer the
behavior of a virtual address range. Lastly, we may want to reject mmap
attempts on a per-mmap-call basis.
This conversion was performed by the following semantic patch. There
were a few manual edits for oddities like proc_reg_mmap, call_mmap,
drm_gem_cma_mmap, and cxl_fd_mmap.
Thanks to Julia for helping me with coccinelle iteration to cover cases
where the mmap routine is defined in a separate file from the operations
instance that consumes it.
