These are userspace objects, so mark them as such. In a later patch it's
useful to determine how paranoid we need to be when managing cache
flushes. In theory no functional changes.

Setting cred->ucounts in cred_alloc_blank does not make sense. The
uid and user_ns are deliberately not set in cred_alloc_blank but
instead the setting is delayed until key_change_session_keyring.
So move dealing with ucounts into key_change_session_keyring as well.
Unfortunately that movement of get_ucounts adds a new failure mode to
key_change_session_keyring. I do not see anything stopping the parent
process from calling setuid and changing the relevant part of it's
cred while keyctl_session_to_parent is running making it fundamentally
necessary to call get_ucounts in key_change_session_keyring. Which
means that the new failure mode cannot be avoided.
A failure of key_change_session_keyring results in a single threaded
parent keeping it's existing credentials. Which results in the parent
process not being able to access the session keyring and whichever
keys are in the new keyring.
Further get_ucounts is only expected to fail if the number of bits in
the refernece count for the structure is too few.
Since the code has no other way to report the failure of get_ucounts
and because such failures are not expected to be common add a WARN_ONCE
to report this problem to userspace.
Between the WARN_ONCE and the parent process not having access to
the keys in the new session keyring I expect any failure of get_ucounts
will be noticed and reported and we can find another way to handle this
condition. (Possibly by just making ucounts->count an atomic_long_t).

The encoder buffer serves as a cache for reference frames during the
encoding process. The encoder buffer significantly reduces the bandwidth
requirement for read accesses on the AXI ports of the VCU, but slightly
reduces the quality of the encoded video.
The encoder buffer must be configured as a whole during the firmware
initialization and later explicitly enabled for every channel that shall
use the encoder buffer.
Prior to firmware version 2019.2, it was necessary to explicitly set the
size of the encoder buffer for every channel. Since 2019.2 it is
sufficient to enable the encoder buffer and leave the rest to the
firmware. Therefore, only support the encoder buffer for firmware 2019.2
and later.

The allegro driver must ensure that the mcu and core clocks are enabled
and set to the expected clock rate before trying to load the firmware
and to reset the MCU.
Up until now, the driver assumed that the clocks are always enabled in
the PL (programming logic), because the xlnx_vcu driver did not export
the clocks to other drivers. This has changed and by explicitly enabling
the clocks in the driver, this assumption can be dropped.
It might even be possible to disable the clocks for the encoder if the
encoder is not used. However, the behavior is not documented and it
might be necessary to reinitialize the encoder after deactivating the
clocks. Play it safe by sticking to the current behavior.

domain->pgc into bitfield for i.MX8MM GPU domain support.
- A series from Lucas Stach adding support of i.MX8MM nested power
domains like VPUMIX and DISPMIX which contains the ADB and BLK_CTRL.
- An off-by-one fix on Lucas' i.MX8M blk-ctrl driver code.

The VCU provides information about its configuration in a dedicated
register space. These settings include, for example, the expected clock
rates and the configuration of the encoder buffer. In the device tree,
the settings are described by the "xlnx,vcu-settings" compatible.
The settings are needed to correctly configure the clocks and the
encoder buffer.
Lookup the VCU settings in the device tree and make it accessible to the
driver via a regmap.

The mailbox is initialized after the interrupt handler is installed. As
the firmware is loaded and started even later, it should not happen that
the interrupt occurs without the mailbox being initialized.
As the Linux Driver Verification project (linuxtesting.org) keeps
reporting this as an error, add a check to ignore interrupts before the
mailbox is initialized to fix this potential null pointer dereference.

Using local kmaps slightly reduces the chances to stray writes, and
the bvec interface cleans up the code a little bit.
Also switch from page_address to bvec_kmap_local for cbv to be on the
safe side and to avoid pointlessly poking into bvec internals.

Calculation of cache_set's cached sectors is done by travelling
cached_devs list as shown below:
static void calc_cached_dev_sectors(struct cache_set *c)
{
...
list_for_each_entry(dc, &c->cached_devs, list)
sectors += bdev_sectors(dc->bdev);
c->cached_dev_sectors = sectors;
}
But cached_dev won't be unlinked from c->cached_devs list until we call
following list_move(&dc->list, &uncached_devices),
so previous fix in 'commit 46010141da
("bcache: recal cached_dev_sectors on detach")' is wrong, now we move
it to its right place.

In register_bcache(), there are several cases we didn't set
correct error info (return value and/or error message):
- if kzalloc() fails, it needs to return ENOMEM and print
"cannot allocate memory";
- if register_cache() fails, it's better to propagate its
return value rather than using default EINVAL.

There sre 3 bits in member high of struct bkey are never used, and no
plan to support them in future,
- HEADER_SIZE, start at bit 58, length 2 bits
- KEY_PINNED, start at bit 55, length 1 bit
No any kernel code, or user space tool references or accesses the three
bits. Therefore it is possible and feasible to reserve the valuable bits
from bkey.high. They can be used in future for other purpose.

Add a driver providing access to the GPIOs for the identify button and led
present on Barco P50 board, based on the pcengines-apuv2.c driver.
There is unfortunately no suitable ACPI entry for the EC communication
interface, so instead bind to boards with "P50" as their DMI product family
and hard code the I/O port number (0x299).
The driver also hooks up the leds-gpio and gpio-keys-polled drivers to the
GPIOs, so they are finally exposed as:
LED:
/sys/class/leds/identify
Button: (/proc/bus/input/devices)
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
