Since ath9k reports airtime usage directly using the
ieee80211_report_airtime() callback, it shouldn't also report it using the
tx_time in status. Make sure the field is zeroed before TX status is
reported to avoid spurious airtime being accounted by bits being left over
from earlier uses of the cb.

The length of wmi tlv command for management tx send is calculated
incorrectly in case of protected management frames as there is addition
of IEEE80211_CCMP_MIC_LEN twice. This leads to improper behaviour of
firmware as the wmi tlv mgmt tx send command for protected mgmt frames
is formed wrongly.
Fix the length calculation of wmi tlv command for mgmt tx send in case
of protected management frames by adding the IEEE80211_CCMP_MIC_LEN only
once.

The SDIO firmware does not provide RSSI value to the host, it's only set to
zero. In that case don't report the value to mac80211. One risk here is that
value zero might be a valid value with other firmware, currently there's no way
to detect that.
Without the fix, the rssi value indicated by iw changes between the actual
value and -95.

This is a theoretical fix, the issue is found in code review.
When adding the host memory chunks into wmi-tlv init command,
there is no separate tlv header for each host memory chunk
in the struct array, which breaches the convention between
host and firmware, will result in mismatch between the two.

When the driver receives the tx completion of the
descriptor over ce, it clears the nbytes configured
for that particular descriptor. WCN3990 uses ce
descriptors with 64-bit address.
Currently during handling the tx completion of the
descriptors, the nbytes are accessed from the descriptors
using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater
than 32 bits.
Attach different ce tx copy completed handler for targets
using address above 32-bit address.

This warning seems to make no sense on the surface because opcode is set
to NULL right below this statement. However, there is a comma instead of
semicolon to end the dialect assignment, meaning that the opcode
assignment only happens in the if statement. Properly terminate that
line so that Clang no longer warns.

The OPAL call wrapper gets interrupt disabling wrong. It disables
interrupts just by clearing MSR[EE], which has two problems:
- It doesn't call into the IRQ tracing subsystem, which means tracing
across OPAL calls does not always notice IRQs have been disabled.
- It doesn't go through the IRQ soft-mask code, which causes a minor
bug. MSR[EE] can not be restored by saving the MSR then clearing
MSR[EE], because a racing interrupt while soft-masked could clear
MSR[EE] between the two steps. This can cause MSR[EE] to be
incorrectly enabled when the OPAL call returns. Fortunately that
should only result in another masked interrupt being taken to
disable MSR[EE] again, but it's a bit sloppy.
The existing code also saves MSR to PACA, which is not re-entrant if
there is a nested OPAL call from different MSR contexts, which can
happen these days with SRESET interrupts on bare metal.
To fix these issues, move the tracing and IRQ handling code to C, and
call into asm just for the low level call when everything is ready to
go. Save the MSR on stack rather than PACA.
Performance cost is kept to a minimum with a few optimisations:
- The endian switch upon return is combined with the MSR restore,
which avoids an expensive context synchronizing operation for LE
kernels. This makes up for the additional mtmsrd to enable
interrupts with local_irq_enable().
- blr is now used to return from the opal_* functions that are called
as C functions, to avoid link stack corruption. This requires a
skiboot fix as well to keep the call stack balanced.
A NULL call is more costly after this, (410ns->430ns on POWER9), but
OPAL calls are generally not performance critical at this scale.

Handlers for interrupts that set DAR / DSISR, set MSR[RI] before those
SPRs are read. If a d-side machine check hits in this window, DAR /

Code that uses HSRR registers is not required to clear MSR[RI] by
convention, however the system reset NMI itself may use HSRR
registers (e.g., to call OPAL) and clobber them.

HSRRs, have system reset interrupt save and restore HSRRs.

HV interrupts that use HSRR registers do not enter with MSR[RI] clear,
but their entry code is not recoverable vs NMI, due to shared use of
HSPRG1 as a scratch register to save r13.
This means that a system reset or machine check that hits in HSRR
interrupt entry can cause r13 to be silently corrupted.
Fix this by marking NMIs non-recoverable if they land in HV interrupt
ranges.

If the provided fwnode is an OF node, set dev.of_node as well.
Also add an of_node_reused flag to struct platform_device_info and copy
this to the new device. This is needed to avoid pinctrl settings being
requested twice. See 4e75e1d7dac9 ("driver core: add helper to reuse a
device-tree node") for a longer explanation.
Some drivers are just shims that create extra "glue" devices with the
DT device as parent and have the real driver bind to these. In these
cases, the glue device needs to get a reference to the original DT node
in order for the main driver to access properties and child nodes.
For example, the sunxi-musb driver creates such a glue device using
platform_device_register_full(). Consequently, devices attached to
this USB interface don't get associated with DT nodes, if present,
the way they do with EHCI.
This change will allow sunxi-musb and similar drivers to easily
propagate the DT node to child devices as required.

One of the more common cases of allocation size calculations is finding

struct foo {

struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable siz is not necessary, hence
