Add a new field, input_audio_fmts, in struct
sof_ipc4_available_audio_format and parse all the available input audio
formats into this new field and not into the base_config field. This is
preparation to remove the base_config array from the struct
sof_ipc4_available_audio_format.
This simplifies the sof_ipc4_init_audio_fmt()
function as the reference audio format for matching with input params
has the same size.

The Wa_14017073508 require to send Media Busy/Idle mailbox while
accessing Media tile. As of now it is getting handled while __gt_unpark,
__gt_park. But there are various corner cases where forcewakes are taken
without __gt_unpark i.e. without sending Busy Mailbox especially during
register reads. Forcewakes are taken without busy mailbox leads to
GPU HANG. So bringing mailbox calls under forcewake calls are no feasible

The ipw_fw_error structure contains a payload[] flexible array as well as
two pointers to this array area, ->elem, and ->log. The total size of the
allocated structure is computed without use of the <linux/overflow.h>
macros.
There's no reason to keep both a payload[] and an extra pointer to both the
elem and log members. Convert the elem pointer member into the flexible
array member, removing payload.
Fix the allocation of the ipw_fw_error structure to use size_add(),
struct_size(), and array_size() to compute the allocation. This ensures
that any overflow saturates at SIZE_MAX rather than overflowing and
potentially allowing an undersized allocation.
Before the structure change, the layout of ipw_fw_error was:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_error_elem * elem; /* 24 8 */
struct ipw_event * log; /* 32 8 */
u8 payload[]; /* 40 0 */
/* size: 40, cachelines: 1, members: 8 */
/* last cacheline: 40 bytes */
};
After this change, the layout is now:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_event * log; /* 24 8 */
struct ipw_error_elem elem[]; /* 32 0 */
/* size: 32, cachelines: 1, members: 7 */
/* last cacheline: 32 bytes */
};
This saves a total of 8 bytes for every ipw_fw_error allocation, and
removes the risk of a potential overflow on the allocation.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

A potentially malicious SEV guest can constantly hammer the hypervisor
using this driver to send down requests and thus prevent or at least
considerably hinder other guests from issuing requests to the secure
processor which is a shared platform resource.
Therefore, the host is permitted and encouraged to throttle such guest
requests.
Add the capability to handle the case when the hypervisor throttles
excessive numbers of requests issued by the guest. Otherwise, the VM
platform communication key will be disabled, preventing the guest from
attesting itself.
Realistically speaking, a well-behaved guest should not even care about
throttling. During its lifetime, it would end up issuing a handful of
requests which the hardware can easily handle.
This is more to address the case of a malicious guest. Such guest should
get throttled and if its VMPCK gets disabled, then that's its own
wrongdoing and perhaps that guest even deserves it.
To the implementation: the hypervisor signals with SNP_GUEST_REQ_ERR_BUSY
that the guest requests should be throttled. That error code is returned
in the upper 32-bit half of exitinfo2 and this is part of the GHCB spec
v2.
So the guest is given a throttling period of 1 minute in which it
retries the request every 2 seconds. This is a good default but if it
turns out to not pan out in practice, it can be tweaked later.
For safety, since the encryption algorithm in GHCBv2 is AES_GCM, control
must remain in the kernel to complete the request with the current
sequence number. Returning without finishing the request allows the
guest to make another request but with different message contents. This
is IV reuse, and breaks cryptographic protections.

Add some more debug prints in processing regulatory WMI event in order to
increase more debuggability.

In order to support different power levels of 6 GHz AP and client,
new WMI event for regulatory - WMI_REG_CHAN_LIST_CC_EXT_EVENTID is
added in firmware. This event provides new parameters required for
6 GHz regulatory rules.
Add support for parsing 2.4 GHz, 5 GHz and 6 GHz reg rules and other
parameters from WMI_REG_CHAN_LIST_CC_EXT_EVENTID.

Currently, during regulatory event, 2 GHz/5 GHz is referred
to as 2G/5G including variable names. However, there is no
such entity as 2G or 5G.
Re-name such occurences to its proper name. No functional changes.

The "cplen" result used by the memcpy() into struct rvt_swqe "wqe" may
be sized to 80 for struct rvt_ud_wr (which is member "ud_wr", not "wr"
which is only 40 bytes in size). Change the destination union member so
the compiler can use the correct bounds check.
struct rvt_swqe {
union {
struct ib_send_wr wr; /* don't use wr.sg_list */
struct rvt_ud_wr ud_wr;
...
};
...
};
Silences false positive memcpy() run-time warning:
memcpy: detected field-spanning write (size 80) of single field "&wqe->wr" at drivers/infiniband/sw/rdmavt/qp.c:2043 (size 40)
