Generalize flow_action_entry cleanup by extending the structure with
pointer to destructor function. Set the destructor in
tc_setup_flow_action(). Refactor tc_cleanup_flow_action() to call
entry->destructor() instead of using switch that dispatches by entry->id
and manually executes cleanup.
This refactoring is necessary for following patches in this series that
require destructor to use tc_action->ops callbacks that can't be easily
obtained in tc_cleanup_flow_action().

Using static analysis, I discovered that the "dpriv->pci_priv->pdev"
pointer is always NULL. This pointer was supposed to be initialized
during probe and is essential for the driver to work. It would be easy
to add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver has
been broken since before we started using git and no one has complained
so probably we should just remove it.

James Harvey reported a livelock that was introduced by commit
d012a06ab1d23 ("Revert "KVM: x86/mmu: Zap only the relevant pages when
removing a memslot"").
The livelock occurs because kvm_mmu_zap_all() as it exists today will
voluntarily reschedule and drop KVM's mmu_lock, which allows other vCPUs
to add shadow pages. With enough vCPUs, kvm_mmu_zap_all() can get stuck
in an infinite loop as it can never zap all pages before observing lock
contention or the need to reschedule. The equivalent of kvm_mmu_zap_all()
that was in use at the time of the reverted commit (4e103134b8623, "KVM:
x86/mmu: Zap only the relevant pages when removing a memslot") employed
a fast invalidate mechanism and was not susceptible to the above livelock.
There are three ways to fix the livelock:
- Reverting the revert (commit d012a06ab1d23) is not a viable option as
the revert is needed to fix a regression that occurs when the guest has
one or more assigned devices. It's unlikely we'll root cause the device
assignment regression soon enough to fix the regression timely.
- Remove the conditional reschedule from kvm_mmu_zap_all(). However, although
removing the reschedule would be a smaller code change, it's less safe
in the sense that the resulting kvm_mmu_zap_all() hasn't been used in
the wild for flushing memslots since the fast invalidate mechanism was
introduced by commit 6ca18b6950f8d ("KVM: x86: use the fast way to
invalidate all pages"), back in 2013.
- Reintroduce the fast invalidate mechanism and use it when zapping shadow
pages in response to a memslot being deleted/moved, which is what this
patch does.
For all intents and purposes, this is a revert of commit ea145aacf4ae8
("Revert "KVM: MMU: fast invalidate all pages"") and a partial revert of
commit 7390de1e99a70 ("Revert "KVM: x86: use the fast way to invalidate
all pages""), i.e. restores the behavior of commit 5304b8d37c2a5 ("KVM:
MMU: fast invalidate all pages") and commit 6ca18b6950f8d ("KVM: x86:
use the fast way to invalidate all pages") respectively.

Emulation of VMPTRST can incorrectly inject a page fault
when passed an operand that points to an MMIO address.
The page fault will use uninitialized kernel stack memory
as the CR2 and error code.
The right behavior would be to abort the VM with a KVM_EXIT_INTERNAL_ERROR
exit to userspace; however, it is not an easy fix, so for now just ensure
that the error code and CR2 are zero.

Part of the intention during the definition of the RISC-V kernel image
header was to lay the groundwork for a future merge with the ARM64
image header. One error during my original review was not noticing
that the RISC-V header's "magic" field was at a different size and
position than the ARM64's "magic" field. If the existing ARM64 Image
header parsing code were to attempt to parse an existing RISC-V kernel
image header format, it would see a magic number 0. This is
undesirable, since it's our intention to align as closely as possible
with the ARM64 header format. Another problem was that the original
"res3" field was not being initialized correctly to zero.
Address these issues by creating a 32-bit "magic2" field in the RISC-V
header which matches the ARM64 "magic" field. RISC-V binaries will
store "RSC\x05" in this field. The intention is that the use of the
existing 64-bit "magic" field in the RISC-V header will be deprecated
over time. Increment the minor version number of the file format to
indicate this change, and update the documentation accordingly. Fix
the assembler directives in head.S to ensure that reserved fields are
properly zero-initialized.

A Mediatek based smartphone owner reports problems with USB
tethering in Linux. The verbose USB listing shows a rndis_host
interface pair (e0/01/03 + 10/00/00), but the driver fails to
bind with
[ 355.960428] usb 1-4: bad CDC descriptors
The problem is a failsafe test intended to filter out ACM serial
functions using the same 02/02/ff class/subclass/protocol as RNDIS.
The serial functions are recognized by their non-zero bmCapabilities.
No RNDIS function with non-zero bmCapabilities were known at the time
this failsafe was added. But it turns out that some Wireless class
RNDIS functions are using the bmCapabilities field. These functions
are uniquely identified as RNDIS by their class/subclass/protocol, so
the failing test can safely be disabled. The same applies to the two
types of Misc class RNDIS functions.
Applying the failsafe to Communication class functions only retains
the original functionality, and fixes the problem for the Mediatek based
smartphone.
Tow examples of CDC functional descriptors with non-zero bmCapabilities
from Wireless class RNDIS functions are:
0e8d:000a Mediatek Crosscall Spider X5 3G Phone
CDC Header:
bcdCDC 1.10
CDC ACM:
bmCapabilities 0x0f

Currently sctp_get_port_local() returns a long
which is either 0,1 or a pointer casted to long.
It's neither of the callers use the return value since
commit 62208f12451f ("net: sctp: simplify sctp_get_port").
Now two callers are sctp_get_port and sctp_do_bind,
they actually assumend a casted to an int was the same as
a pointer casted to a long, and they don't save the return
value just check whether it is zero or non-zero, so
it would better change return type from long to int for
sctp_get_port_local.

Enable setting skb->mark for UDP and RAW sockets using cmsg.
This is analogous to existing support for TOS, TTL, txtime, etc.
Packet sockets already support this as of commit c7d39e32632e
("packet: support per-packet fwmark for af_packet sendmsg").
Similar to other fields, implement by
1. initialize the sockcm_cookie.mark from socket option sk_mark
2. optionally overwrite this in ip_cmsg_send/ip6_datagram_send_ctl
3. initialize inet_cork.mark from sockcm_cookie.mark
4. initialize each (usually just one) skb->mark from inet_cork.mark
Step 1 is handled in one location for most protocols by ipcm_init_sk
as of commit 351782067b6b ("ipv4: ipcm_cookie initializers").

Power amplifiers are not linear components, and require DPK to
reduce its nonlinearity. DPK is called Digital Pre-distortion
Calibration, can be used to compensate the output of power.
DPK tracking is in charge of tracking the thermal changes. And
it then shifts the power curve accordingly, which makes the
power output remains linear even if the PA works in different
temperature.
To perform DPK, the parameter table should also be updated.
And the table will be applied when device is powered on.
Then DPK will reference the values to calibrate.

Add support for doing IQK in firmware
Ideally the RF component's I/Q vectors should be orthogonal,
but usually they are not. So we need to calibrate for the RF
components, ex. PA/LNA, ADC/DAC.
And if the I/Q vectors are more orthogonal, the mixed signal
will have less deviation. This helps with those rates with
higher modulation (MCS8-9), because they have more strict
EVM/SNR requirement. Also the better of the quality of the
signal, the longer it can propagate, and the better throughput
performance we can get.

The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d
but is perhaps more readable.

Arrays pwr_info_offset and sprom_sizes can be make static const rather
than populating them on the stack. Shrinks object size by 236 bytes.
Before:
text data bss dec hex filename
11300 1320 64 12684 318c drivers/bcma/sprom.o
After:
text data bss dec hex filename
10904 1480 64 12448 30a0 drivers/bcma/sprom.o
(gcc version 9.2.1, amd64)

The array channel_all can be make static const rather than populating
it on the stack, this makes the code smaller. Also, variable place
is being initialized with a value that is never read, so this assignment
is redundant and can be removed.
Before:
text data bss dec hex filename
118537 9591 0 128128 1f480 realtek/rtlwifi/rtl8821ae/phy.o
After:
text data bss dec hex filename
118331 9687 0 128018 1f412 realtek/rtlwifi/rtl8821ae/phy.o
Saves 110 bytes, (gcc version 9.2.1, amd64)

Providing a new wiphy on every PCIe reset was confusing and was causing
configuration problems for some users (supplicant and authenticators).
Sticking to the existing wiphy should make error recovery much simpler
and more reliable.

Move code allocating/freeing wiphy out of above functions. This will
allow reinitializing the driver (e.g. on some error) without allocating
a new wiphy.
