platform_get_resource() may fail, so we should better check its
return value and propagate an error in case it fails.
This avoids a NULL pointer dereference a bit later in the code.

platform_device_id are not supposed to change at runtime. All functions
working with platform_device_id provided by <linux/platform_device.h>
work with const platform_device_id. So mark the non-const structs as

These watchdog_ops and watchdog_info structures are only stored
in the ops and info fields of a watchdog_device structure,
respectively, which are const. Thus make the watchdog_ops and
watchdog_info structures const as well.
Done with the help of Coccinelle. The rules for the watchdog_ops case are
as follows:
// <smpl>
@r disable optional_qualifier@
identifier i;

static struct watchdog_ops i@p = { ... };
@ok@

The error margin of the clks_per_second variable was too large and
caused offsets when used with clock frequencies which left a remainder
after applying the dividers. Now we always calculate directly using the
clock rate and the divider using some helper macros. That also means
that DIV_ROUND_UP moves from probe to the multiplication macro. In
probe, we don't need to ensure anymore that 'clks_per_sec' would go too
fast but rather ensure that the lower limit is really at least 1 to
certainly get a full cycle.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

The watchdog IP block on Meson8 and Meson8m2 is already supported by the
existing meson-wdt driver. Meson8 uses the same register bits as Meson6,
while the newer Meson8m2 SoC uses the same register bits as Meson8b.
Currently watchdog support on Meson8 SoC already works because
meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a
separate compatible for Meson8 makes this more explicit though.

Pull kselftest updates from Shuah Khan:
- TAP13 framework API and converting tests to TAP13 continues. A few
more tests are converted and kselftest common RUN_TESTS in lib.mk is
enhanced to print TAP13 to cover test shell scripts that won't be
able to use kselftest API.
- Several fixes to existing tests to not fail in unsupported cases.
This has been an ongoing work based on the feedback from stable
release kselftest users.
- A new watchdog test and much needed cleanups to the existing tests
from Eugeniu Rosca.
- Changes to kselftest common lib.mk framework to make RUN_TESTS a
function to be called from individual test make files to run stress
and destructive sub-tests.

I had stupidly missed one special use of 'is_reserved_word()' when I
converted the code to avoid gperf.
I had changed that function to return the token ID directly rather than
a pointer to the token descriptor structure, but that meant that the
test for "is this a reserved word" changed from checking the return
value against NULL, to checking that it wasn't negative.
And while I had converted the main token parser over, I missed the
special case of the typeof phrase handling. And since our dependency
chain for genksyms does not include the genksyms program itself
changing, my kernel rebuild didn't show the problem.

The fix in the parent made me look at that function, and react to how
illogical and illegible the array initializer was.
Use named array indexes to make it clearer what is going on, and make
the initializer not depend silently on the exact index numbers.
[ The initializer now also shows an odd inconsistency in the naming:
note the IWCM vs IWPM.. - Linus ]

This fix was intended for 4.13, but didn't get in because both
maintainers were on vacation.
Paul Mackerras:
"It adds mutual exclusion between list_add_rcu and list_del_rcu calls
on the kvm->arch.spapr_tce_tables list. Without this, userspace could
potentially trigger corruption of the list and cause a host crash or
worse."

Remove our use of 'gperf' for generating perfect hashes from some of our
build tools.
This removal was prompted by Masahiro Yamada sending out a patch that
removes all our pre-generated files, and when I tested it, I noticed
that the gperf version I have (3.1) apparently generates code that no
longer works with out code-base because the function interfaces
generated by gperf have changed.
We really don't care that much, and the gperf people changed their
interfaces in ways that makes it annoying to work with them. Tools that
make it hard to use them should not be used, and the kernel is not at
all interested in some autoconf mess. So remove the gperf dependency
entirely.
It turns out that if you ignore the pre-generated files, the use of
gperf apparently saved us a whopping fifteen lines of code. It
obviously wasn't worth it, considering that the pre-generated files are
about 500 lines.
I sent this out as a patch about three weeks ago, and got absolutely
zero responses. So let's see if anybody notices now that I merge it.
Because there might be serious bugs here, but it WorksForMe(tm).
