Add a devlink parameter to control the number of large groups in a
autogrouped flow table. The default value is 15, and the range is between 1
and 1024.
The size of each large group can be calculated according to the following
formula: size = 4M / (fdb_large_groups + 1).
Examples:
- Set the number of large groups to 20.
$ devlink dev param set pci/0000:82:00.0 name fdb_large_groups \
cmode driverinit value 20
Then run devlink reload command to apply the new value.
$ devlink dev reload pci/0000:82:00.0
- Read the number of large groups in flow table.
$ devlink dev param show pci/0000:82:00.0 name fdb_large_groups
pci/0000:82:00.0:
name fdb_large_groups type driver-specific
values:
cmode driverinit value 20

When using port mirroring, we forward the traffic to another table and
use that table to forward to the mirrored vport. Since the hardware
loses the values of reg c, and in particular reg c0, we fail the match
on the input vport which previously existed in reg c0. To overcome this
situation, we use a set of per vport tables, positioned at the lowest
priority, and forward traffic to those tables. Since these tables are
per vport, we can avoid matching on reg c0.

If the status value returned by acpi_install_address_space_handler()
in ec_install_handlers() is AE_NOT_FOUND, it is treated in a special
way, apparently because it might mean a _REG method evaluation
failure (at least that is the case according to the comment in
there), but acpi_install_address_space_handler() does not take
_REG evaluation errors into account at all, so the AE_NOT_FOUND
special handling is confusing at best.
For this reason, change ec_install_handlers() to stop the EC and
return -ENODEV on all acpi_install_address_space_handler() errors.

After commit 406857f773b0 ("ACPI: EC: add support for hardware-reduced
systems") the handle_events argument passed to ec_install_handlers()
and acpi_ec_setup() is redundant, because it is always 'false' when
the device argument passed to them in NULL and it is always 'true'
otherwise, so the device argument can be tested against NULL instead
of testing the handle_events one.
Accordingly, modify ec_install_handlers() and acpi_ec_setup() to take
two arguments and reduce the number of checks in the former.

It doesn't really make sense to pass ec->handle of the ECDT EC to
acpi_handle_info(), because it is set to ACPI_ROOT_OBJECT in
acpi_ec_ecdt_probe(), so rework acpi_ec_setup() to avoid using
acpi_handle_info() for printing messages.
First, notice that the "Used as first EC" message is not really
useful, because it is immediately followed by a more meaningful one
from either acpi_ec_ecdt_probe() or acpi_ec_dsdt_probe() (the latter
also includes the EC object path), so drop it altogether.
Second, use pr_info() for printing the EC configuration information.
While at it, make the code in question avoid printing invalid GPE or
IRQ numbers and make it print the GPE/IRQ information only when the
driver is ready to handle events.

After this warning, following refcount API calls for the counter all fail
to change the counter value.
Fix this by setting the initial reference counter value not zero but one
for the new chunk works. Instead, do not call refcount_inc() via
dmz_get_chunk_work() for the new chunks works.
The failure was observed with linux version 5.4 with CONFIG_REFCOUNT_FULL
enabled. Refcount rework was merged to linux version 5.5 by the
commit 168829ad09ca ("Merge branch 'locking-core-for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip"). After this
commit, CONFIG_REFCOUNT_FULL was removed and the failure was observed
regardless of kernel configuration.
Linux version 4.20 merged the commit 092b5648760a ("dm zoned: target: use
refcount_t for dm zoned reference counters"). Before this commit, dm
zoned used atomic_t APIs which does not check addition to zero, then this
fix is not necessary.

The function dm_suspended returns true if the target is suspended.
However, when the target is being suspended during unload, it returns
false.
An example where this is a problem: the test "!dm_suspended(wc->ti)" in
writecache_writeback is not sufficient, because dm_suspended returns
zero while writecache_suspend is in progress. As is, without an
enhanced dm_suspended, simply switching from flush_workqueue to
drain_workqueue still emits warnings:
workqueue writecache-writeback: drain_workqueue() isn't complete after 10 tries
workqueue writecache-writeback: drain_workqueue() isn't complete after 100 tries
workqueue writecache-writeback: drain_workqueue() isn't complete after 200 tries
workqueue writecache-writeback: drain_workqueue() isn't complete after 300 tries
workqueue writecache-writeback: drain_workqueue() isn't complete after 400 tries
writecache_suspend calls flush_workqueue(wc->writeback_wq) - this function
flushes the current work. However, the workqueue may re-queue itself and
flush_workqueue doesn't wait for re-queued works to finish. Because of
this - the function writecache_writeback continues execution after the
device was suspended and then concurrently with writecache_dtr, causing
a crash in writecache_writeback.
We must use drain_workqueue - that waits until the work and all re-queued
works finish.
As a prereq for switching to drain_workqueue, this commit fixes
dm_suspended to return true after the presuspend hook and before the
postsuspend hook - just like during a normal suspend. It allows
simplifying the dm-integrity and dm-writecache targets so that they
don't have to maintain suspended flags on their own.
With this change use of drain_workqueue() can be used effectively. This
change was tested with the lvm2 testsuite and cryptsetup testsuite and
the are no regressions.

During initialization the driver issues a reset to the device and waits
for 100ms before checking if the firmware is ready. The waiting is
necessary because before that the device is irresponsive and the first
read can result in a completion timeout.
While 100ms is sufficient for Spectrum-1 and Spectrum-2, it is
insufficient for Spectrum-3.
Fix this by increasing the timeout to 200ms.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

We can't just use the top bits of the last sync event as they could be
off-by-one every 65,536 seconds, giving an error in reconstruction of
65,536 seconds.
This patch uses the difference in the bottom 16 bits (mod 2^16) to
calculate an offset that needs to be applied to the last sync event to
get to the current time.

Convert the DPAA2 ethernet driver to use the finalised link parameters
in mac_link_up() rather than the parameters in mac_config(), which are
more suited to the needs of the DPAA2 MC firmware than those available
via mac_config().

Propagate the resolved link configuration down via DSA's
phylink_mac_link_up() operation to allow split PCS/MAC to work.

Propagate the resolved link parameters via the mac_link_up() call for
MACs that do not automatically track their PCS state. We propagate the
link parameters via function arguments so that inappropriate members
of struct phylink_link_state can't be accessed, and creating a new
structure just for this adds needless complexity to the API.
