On the first wiphy, hw->priv will point to struct mt76_dev, which contains a
struct mt76_phy at the start. For the secondary wiphy, hw->priv will point
to a mt76_phy encapsulated in a driver specific struct
To simplify access to struct mt76_phy members from drivers, the driver specific
device struct is changed to add a union of struct mt76_dev and struct mt76_phy
as the first element

Some tests shows that using AMSDU to aggregate TCP ACKs to specific
APs will degrade the throughput on 2.4G band in 20MHz bandwidth
(< 10 Mbps, should be ~100 Mbps for 2x2). Also found that there's
barely no negative impact if we disable TX AMSDU on 2.4G to connect
to other APs. So it seems like we can just tell mac80211 to not to
aggregate MSDUs when transmitting on 2.4G band.
Note that we still can TX AMSDU on 5G band and benefit from it by
having 50 ~ 70 Mbps throughput improvement.

According to some experiments, the original RF register protection
setting of 8822c cannot perfectly make sure that there is no hardware
PI write (direct) during direct write. Modify the setting so that the
hardware block of PI would be turned off via rtw8822c_rstb_3wire()
during the direct write, to avoid RF register racing.
Note that 8822b uses SIPI write (indirect), so 8822b does not
have such problem.

Driver could possibly be dead-locked while canceling works with
*_sync() with mutex lock held. Those cancel_delayed_work_sync()
functions will wait until the work is done, but if we hold the
lock, they will never acquire the lock.
To prevent this, simply release the lock and acquire again after
the works have been canceled. And to avoid the works being queued
again, check if the device is at RTW_FLAG_RUNNING state, otherwise
just return and do nothing.

When driver is coming up, mac80211 will set changed as ~0 (0xffffffff),
and driver could enter IDLE state (power off) before switching channel or
other config event. So move rtw_enter_ips() to the last, to make sure the
driver completed the config events before going to IDLE state.
So, moves leave/enter IPS config to be first/last one according to flag
IEEE80211_CONF_IDLE. If there're more configureations we want to add in
the future, they must locate between leave/enter IPS.

Use MAJOR.MINOR format for QLink firmware protocol. MAJOR part is
incremented when backward compatibility is broken. Normally this
part should not be incremented unless there is a good reason for
that. MINOR part is incremented each time when new features are
added to qlink.h, e.g. new TLVs, events, commands. These changes
should not break backward compatibility. For instance, older
firmware versions may not be able to parse new flags or send new
types of events, but this does not impact normal system operations.
As part of initialization sequence, driver requests protocol version
from firmware and refuses to start in case there is a mismatch in MAJOR
part of the version.

Zonefs is a very simple file system exposing each zone of a zoned block
device as a file.
Unlike a regular file system with native zoned block device support
(e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
sequential write constraint of zoned block devices to the user. As a
result, zonefs is not a POSIX compliant file system. Its goal is to
simplify the implementation of zoned block devices support in
applications by replacing raw block device file accesses with a richer
file based API, avoiding relying on direct block device file ioctls
which may be more obscure to developers.
One example of this approach is the implementation of LSM
(log-structured merge) tree structures (such as used in RocksDB and
LevelDB) on zoned block devices by allowing SSTables to be stored in a
zone file similarly to a regular file system rather than as a range of
sectors of a zoned device. The introduction of the higher level
construct "one file is one zone" can help reducing the amount of changes
needed in the application while at the same time allowing the use of
zoned block devices with various programming languages other than C.
Zonefs IO management implementation uses the new iomap generic code.
Zonefs has been successfully tested using a functional test suite
(available with zonefs userland format tool on github) and a prototype
implementation of LevelDB on top of zonefs.

TSC and APIC frequencies are already known.
- Handle malformed SRAT tables during early ACPI parsing which caused an

- Fix a long standing race in the affinity setting code which affects PCI
devices with non-maskable MSI interrupts. The problem is caused by the
non-atomic writes of the MSI address (destination APIC id) and data
(vector) fields which the device uses to construct the MSI message. The
non-atomic writes are mandated by PCI.
If both fields change and the device raises an interrupt after writing
address and before writing data, then the MSI block constructs a
inconsistent message which causes interrupts to be lost and subsequent
malfunction of the device.
The fix is to redirect the interrupt to the new vector on the current
CPU first and then switch it over to the new target CPU. This allows to
observe an eventually raised interrupt in the transitional stage (old
CPU, new vector) to be observed in the APIC IRR and retriggered on the
new target CPU and the new vector. The potential spurious interrupts
caused by this are harmless and can in the worst case expose a buggy
driver (all handlers have to be able to deal with spurious interrupts as
they can and do happen for various reasons).
- Add the missing suspend/resume mechanism for the HYPERV hypercall page
which prevents resume hibernation on HYPERV guests. This change got
lost before the merge window.
- Mask the IOAPIC before disabling the local APIC to prevent potentially
stale IOAPIC remote IRR bits which cause stale interrupt lines after
resume.

an infinite loop anda boot hang.
- Fix a long standing race in the affinity setting code which affects
PCI devices with non-maskable MSI interrupts. The problem is caused
by the non-atomic writes of the MSI address (destination APIC id)
and data (vector) fields which the device uses to construct the MSI
message. The non-atomic writes are mandated by PCI.
If both fields change and the device raises an interrupt after
writing address and before writing data, then the MSI block
constructs a inconsistent message which causes interrupts to be
lost and subsequent malfunction of the device.
The fix is to redirect the interrupt to the new vector on the
current CPU first and then switch it over to the new target CPU.
This allows to observe an eventually raised interrupt in the
transitional stage (old CPU, new vector) to be observed in the APIC
IRR and retriggered on the new target CPU and the new vector.
The potential spurious interrupts caused by this are harmless and
can in the worst case expose a buggy driver (all handlers have to
be able to deal with spurious interrupts as they can and do happen
for various reasons).
- Add the missing suspend/resume mechanism for the HYPERV hypercall
page which prevents resume hibernation on HYPERV guests. This
change got lost before the merge window.
- Mask the IOAPIC before disabling the local APIC to prevent
potentially stale IOAPIC remote IRR bits which cause stale
interrupt lines after resume"

x86/apic: Mask IOAPIC entries when disabling the local APIC
x86/hyperv: Suspend/resume the hypercall page for hibernation
x86/apic/msi: Plug non-maskable MSI affinity race
x86/boot: Handle malformed SRAT tables during early ACPI parsing
x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode
- Make the UP version of smp_call_function_single() match SMP semantics
when called for a not available CPU. Instead of emitting a warning and
assuming that the function call target is CPU0, return a proper error
code like the SMP version does.
- Remove a superfluous check in smp_call_function_many_cond()
