The Rohm BD2802 have no in-kernel users so we can drop the
GPIO number from the platform data and require users to
provide the GPIO line using machine descriptors.
As the descriptors come with inherent polarity inversion
semantics, we invert the calls to set the GPIO line such
that 0 means "unasserted" and 1 means "asserted".
Put a note in the driver that machine descriptor tables
will need to specify that the line is active low.

When storing a pointer to a dst_metrics structure in dst_entry._metrics,
two flags are added in the least significant bits of the pointer value.
Hence this assumes all pointers to dst_metrics structures have at least
4-byte alignment.
However, on m68k, the minimum alignment of 32-bit values is 2 bytes, not
4 bytes. Hence in some kernel builds, dst_default_metrics may be only
2-byte aligned, leading to obscure boot warnings like:

When a PHY is probed, if the top bit is set, we end up requesting a
module with the string "mdio:-10101110000000100101000101010001" -
the top bit is printed to a signed -1 value. This leads to the module
not being loaded.
Fix the module format string and the macro generating the values for
it to ensure that we only print unsigned types and the top bit is
always 0/1. We correctly end up with
"mdio:10101110000000100101000101010001".

printouts and validate command parameters for nodes using a
<z.c.n> node address, it needs to be able to read the legacy

the workarounds in its own, we don't need these typedefs any longer in

The recent changes in uapi/asoundlib.h caused some build errors in

The hdspm.h uapi header has been used also from non-Linux or platforms
that don't have linux/*.h. It was OK in the past because alsa-lib
contained the modified version of this header file, but now it tries

Recently alsa-lib updated its content of sound/hdsp.h just by copying
the latest Linus kernel uapi/*.h, and this broke the build of
alsa-tools programs. We used to modify the headers so that they can
be built without asoundlib.h and linux kernel headers, and the
verbatim copy doesn't work as is.
This patch removes again the linux/types.h inclusion and drop __user
prefix that broke the build and adjusts the corresponding code.

Recently we updated the content in alsa-lib uapi header files by just
copying from the latest Linus kernel uapi/*.h, and noticed that it
broke the build of some alsa-tools programs. The reason is that we
used to have a modified version in the past, so that the program can
be built without referring to the unexported stuff like
snd_ctl_elem_id or __user prefix.
This patch attempts to restore that, i.e. dropping the stuff that
can't be referred in the user-space. For adapting the changes in
uapi/emu10k1.h, the emu10k1 driver code is also slightly modified.
Most of changes are pointer cast.

Currently these macros are defined to re-initialize a front/back ring
(respectively) to values read from the shared ring in such a way that any
requests/responses that are added to the shared ring whilst the front/back
is detached will be skipped over. This, in general, is not a desirable
semantic since most frontend implementations will eventually block waiting
for a response which would either never appear or never be processed.
Since the macros are currently unused, take this opportunity to re-define
them to re-initialize a front/back ring using specified values. This also
allows FRONT/BACK_RING_INIT() to be re-defined in terms of
FRONT/BACK_RING_ATTACH() using a specified value of 0.
NOTE: BACK_RING_ATTACH() will be used directly in a subsequent patch.

If a driver probe() fails then leave the xenstore state alone. There is no
reason to modify it as the failure may be due to transient resource
allocation issues and hence a subsequent probe() may succeed.
If the driver supports re-binding then only force state to closed during
remove() only in the case when the toolstack may need to clean up. This can
be detected by checking whether the state in xenstore has been set to
closing prior to device removal.
NOTE: Re-bind support is indicated by new boolean in struct xenbus_driver,
which defaults to false. Subsequent patches will add support to
some backend drivers.

Some of the algorithm unregistration functions return -ENOENT when asked
to unregister a non-registered algorithm, while others always return 0
or always return void. But no users check the return value, except for
two of the bulk unregistration functions which print a message on error
but still always return 0 to their caller, and crypto_del_alg() which
calls crypto_unregister_instance() which always returns 0.
Since unregistering a non-registered algorithm is always a kernel bug
but there isn't anything callers should do to handle this situation at
runtime, let's simplify things by making all the unregistration
functions return void, and moving the error message into
crypto_unregister_alg() and upgrading it to a WARN().

Extend the functionality of AMD Secure Processor (SP) driver by
providing an in-kernel API to submit commands to TEE ring buffer for
processing by Trusted OS running on AMD Secure Processor.
Following TEE commands are supported by Trusted OS:
* TEE_CMD_ID_LOAD_TA : Load Trusted Application (TA) binary into
TEE environment
* TEE_CMD_ID_UNLOAD_TA : Unload TA binary from TEE environment
* TEE_CMD_ID_OPEN_SESSION : Open session with loaded TA
* TEE_CMD_ID_CLOSE_SESSION : Close session with loaded TA
* TEE_CMD_ID_INVOKE_CMD : Invoke a command with loaded TA
* TEE_CMD_ID_MAP_SHARED_MEM : Map shared memory
* TEE_CMD_ID_UNMAP_SHARED_MEM : Unmap shared memory
Linux AMD-TEE driver will use this API to submit command buffers
for processing in Trusted Execution Environment. The AMD-TEE driver
shall be introduced in a separate patch.

The common use-case in production is to have multiple cgroup-bpf
programs per attach type that cover multiple use-cases. Such programs
are attached with BPF_F_ALLOW_MULTI and can be maintained by different
people.
Order of programs usually matters, for example imagine two egress
programs: the first one drops packets and the second one counts packets.
If they're swapped the result of counting program will be different.
It brings operational challenges with updating cgroup-bpf program(s)
attached with BPF_F_ALLOW_MULTI since there is no way to replace a
program:
* One way to update is to detach all programs first and then attach the
new version(s) again in the right order. This introduces an
interruption in the work a program is doing and may not be acceptable
(e.g. if it's egress firewall);
* Another way is attach the new version of a program first and only then
detach the old version. This introduces the time interval when two
versions of same program are working, what may not be acceptable if a
program is not idempotent. It also imposes additional burden on
program developers to make sure that two versions of their program can
co-exist.
Solve the problem by introducing a "replace" mode in BPF_PROG_ATTACH
command for cgroup-bpf programs being attached with BPF_F_ALLOW_MULTI
flag. This mode is enabled by newly introduced BPF_F_REPLACE attach flag
and bpf_attr.replace_bpf_fd attribute to pass fd of the old program to
replace
That way user can replace any program among those attached with
BPF_F_ALLOW_MULTI flag without the problems described above.
Details of the new API:
* If BPF_F_REPLACE is set but replace_bpf_fd doesn't have valid
descriptor of BPF program, BPF_PROG_ATTACH will return corresponding
error (EINVAL or EBADF).
* If replace_bpf_fd has valid descriptor of BPF program but such a
program is not attached to specified cgroup, BPF_PROG_ATTACH will
return ENOENT.
BPF_F_REPLACE is introduced to make the user intent clear, since
replace_bpf_fd alone can't be used for this (its default value, 0, is a
valid fd). BPF_F_REPLACE also makes it possible to extend the API in the
future (e.g. add BPF_F_BEFORE and BPF_F_AFTER if needed).

Now that all XDP maps that can be used with bpf_redirect_map() tracks
entries to be flushed in a global fashion, there is not need to track
that the map has changed and flush from xdp_do_generic_map()
anymore. All entries will be flushed in xdp_do_flush_map().
This means that the map_to_flush can be removed, and the corresponding
checks. Moving the flush logic to one place, xdp_do_flush_map(), give
a bulking behavior and performance boost.

Since the battery internal resistance can be changed with the temperature
changes, thus add a resistance temperature table support to look up
the accurate battery internal resistance in a certain temperature.

Introduces a new Qdisc, which is based on 802.1Q-2014 wording. It is
PRIO-like in how it is configured, meaning one needs to specify how many
bands there are, how many are strict and how many are dwrr, quanta for the
latter, and priomap.
The new Qdisc operates like the PRIO / DRR combo would when configured as
per the standard. The strict classes, if any, are tried for traffic first.
When there's no traffic in any of the strict queues, the ETS ones (if any)
are treated in the same way as in DRR.

Entity currently keeps a copy of run_queue list and modify it in
drm_sched_entity_set_priority(). Entities shouldn't modify run_queue
list. Use drm_gpu_scheduler list instead of drm_sched_rq list
in drm_sched_entity struct. In this way we can select a runqueue based
on entity/ctx's priority for a drm scheduler.

The current structures are not well designed. We include Xtensa
information from the ACPI and PCI levels, but at the Kconfig/module
level everything Xtensa related is included at the sof/intel level.
Move the arch_ops under ops so that Xtensa is hidden in the DSP ops,
with a structure that follows the Kconfig/module partition.
