include the new .dtsi files, resulting in exactly the same behavior as
earlier.
The .dtsi files can now be reused for compile time tests using

This is required because the base files passed to fdtoverlay tool
shouldn't be overlays themselves (i.e. shouldn't have the /plugin/;
tag).
Note that this commit also moves "testcase-device2" node to
testcases.dts from tests-interrupts.dtsi, as this node has a deliberate

dt-validate has an option to warn on any compatible strings which don't
match any schema. The option has recently been improved to fix false
positives, so let's enable the option. This is useful for tracking
compatibles which are undocumented or not yet converted to DT schema.
Previously, the only check of undocumented compatible strings has been
an imperfect checkpatch.pl check.
The option is enabled by default for 'dtbs_check'. This will add more
warnings, but some platforms are down to only a handful of these
warnings (good job!).
There's about 100 cases in the binding examples, so the option is
disabled until these are fixed. In the meantime, they can be checked
with:

3c985d31ad66 ("powerpc: Use common
of_kexec_alloc_and_setup_fdt()") changed the kexec code to use the
generic function of_kexec_alloc_and_setup_fdt() which already includes
the base FDT size. That change made the code overestimate the size a bit
by counting twice the space required for the kernel command line and
/chosen properties.
Therefore change kexec_fdt_totalsize_ppc64() to calculate just the extra
space needed by the kdump kernel, and change the function name so that it
better reflects what the function is now doing.

was cred. Move it into issue instead, and we can drop all of that
code too.
- Kill f_op->flush() usage. That was such a nasty hack that we had
out of necessity, we no longer need it.
- Following from ->flush() removal, we can also drop various bits of
ctx state related to SQPOLL and cancelations.
- Fix an issue with IOPOLL retry, which originally was fallout from a
filemap change (removing iov_iter_revert()), but uncovered an issue
with iovec re-import too late.
- Fix an issue with system suspend.
- Use xchg() for fallback work, instead of cmpxchg().
- Properly destroy io-wq on exec.
- Add create_io_thread() core helper, and use that in io-wq and
io_uring. This allows us to remove various silly completion events
related to thread setup.

io_uring: make SQPOLL thread parking saner
We have this weird true/false return from parking, and then some of the
callers decide to look at that. It can lead to unbalanced parks and
sqd locking. Have the callers check the thread status once it's parked.
We know we have the lock at that point, so it's either valid or it's NULL.
Fix race with parking on thread exit. We need to be careful here with
ordering of the sdq->lock and the IO_SQ_THREAD_SHOULD_PARK bit.
