Patch series "remove Xen tmem leftovers".

Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap.  This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.

This patch (of 13):

The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49 ("xen: remove tmem driver").

Check user page table entries at the time they are added and removed.

Allows to synchronously catch memory corruption issues related to double
mapping.

When a pte for an anonymous page is added into page table, we verify
that this pte does not already point to a file backed page, and vice
versa if this is a file backed page that is being added we verify that
this page does not have an anonymous mapping

We also enforce that read-only sharing for anonymous pages is allowed
(i.e.  cow after fork).  All other sharing must be for file pages.

Page table check allows to protect and debug cases where "struct page"
metadata became corrupted for some reason.  For example, when refcnt or
mapcount become invalid.

As has been discussed some time ago on ksumitt-discuss@ mailinglist,
the need for trivial tree diminished over time as all the tooling and
processess became much more mature and it's quite natural these days
for trivial patches to flow through subsystem trees anyway, so the
spin-off of a trivial tree doesn't make sense any more, and is not worth
the merge conflicts it might sometimes create.

So remove any mentions of it from kernel documentation for good.

Add a new driver for the LetSketch / VSON WP9620N drawing tablet. This
drawing tablet is also sold under other brand names such as Case U,
presumably this driver will work for all of them. But it has only been
tested with a LetSketch WP9620N model.

These tablets also work without a special HID driver, but then only
part of the active area works and both the pad and stylus buttons are
hardwired to special key-combos. E.g. the 2 stylus buttons send right
mouse clicks / resp. "e" key presses.

Realtek MIPS SoCs (platform name Otto) have a watchdog timer with
pretimeout notifitication support. The WDT can (partially) hard reset,
or soft reset the SoC.

This driver implements all features as described in the devicetree
binding, except the phase2 interrupt, and also functions as a restart
handler. The cpu reset mode is considered to be a "warm" restart, since
this mode does not reset all peripherals. Being an embedded system
though, the "cpu" and "software" modes will still cause the bootloader
to run on restart.

It is not known how a forced system reset can be disabled on the
supported platforms. This means that the phase2 interrupt will only fire
at the same time as reset, so implementing phase2 is of little use.
