The RISC-V architecture has a register named the "Supervisor Exception
Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's
misspelling detector, resulting in noise in the checkpatch output. The
risk that this noise could cause more useful warnings to be missed seems
to outweigh the harm of an occasional misspelling of "spec". Thus drop
the "sepc" entry from the misspelling list.

Sometimes the register status can include interrupts that
were masked. We can, for example, get the RF-Kill bit set
in the interrupt status register although this interrupt
was masked. Then if we get the ALIVE interrupt (for example)
that was not masked, we need to *not* service the RF-Kill
interrupt.
Fix this in the MSI-X interrupt handler.

Newest devices have a new firmware load mechanism. This
mechanism is called the context info. It means that the
driver doesn't need to load the sections of the firmware.
The driver rather prepares a place in DRAM, with pointers
to the relevant sections of the firmware, and the firmware
loads itself.
At the end of the process, the firmware sends the ALIVE
interrupt. This is different from the previous scheme in
which the driver expected the FH_TX interrupt after each
section being transferred over the DMA.
In order to support this new flow, we enabled all the
interrupts. This broke the assumption that we have in the
code that the RF-Kill interrupt can't interrupt the firmware
load flow.
Change the context info flow to enable only the ALIVE
interrupt, and re-enable all the other interrupts only
after the firmware is alive. Then, we won't see the RF-Kill
interrupt until then. Getting the RF-Kill interrupt while
loading the firmware made us kill the firmware while it is
loading and we ended up dumping garbage instead of the firmware
state.
Re-enable the ALIVE | RX interrupts from the ISR when we
get the ALIVE interrupt to be able to get the RX interrupt
that comes immediately afterwards for the ALIVE
notification. This is needed for non MSI-X only.

We added code to restock the buffer upon ALIVE interrupt
when MSI-X is disabled. This was added as part of the context
info code. This code was added only if the ISR debug level
is set which is very unlikely to be related.
Move this code to run even when the ISR debug level is not
set.
Note that gen2 devices work with MSI-X in most cases so that
this path is seldom used.

In AP (and IBSS) mode, we can only set GTKs to firmware after we have
sent down the multicast station, but this we can only do after we've
enabled beaconing, etc.
However, during rfkill exit, hostapd will configure the keys before
starting the AP, and cfg80211/mac80211 accept it happily.
On earlier devices, this didn't bother us as GTK TX wasn't really
handled in firmware, we just put the key material into the TX cmd
and thus it only mattered when we actually transmitted a frame.
On newer devices, however, the firmware needs to track all of this
and that doesn't work if we add the key before the (multicast) sta
it belongs to.
To fix this, keep a list of keys to add during AP enable, and call
the function there.

Improve the robustness of the dump collection flow in case of an early
error:
1. in iwl_trans_pcie_sync_nmi, disable and enable interrupts only if
they were already enabled
2. attempt to initiate dump collection in iwl_fw_dbg_error_collect only
if the device is enabled
3. check Tx command queue was already allocated before trying to collect it

As iwl_mvm_tx_mpdu() is not disabling BH while obtaining iwl_mvm_sta->lock
(which is being taken from BH context as well), it has to be always
invoked with BH disabled. Make that clear in a comment.

Fixes checkpatch warnings:
drivers/net/wireless/ath/ath10k/pci.c:926: unnecessary cast may hide bugs, see http://c-faq.com/malloc/mallocnocast.html
drivers/net/wireless/ath/ath10k/pci.c:1072: unnecessary cast may hide bugs, see http://c-faq.com/malloc/mallocnocast.html
While at it, also remove unnecessary initialisation of data_buf variable in both cases.

The workqueue need to flush and destory while remove sdio module,
otherwise it will have thread which is not destory after remove
sdio modules.

ath10k will receive some message with invalid peer id from firmware.
reason is:
There are incoming frames to MAC hardware that NOT find relative
address search table, then peer id is invalid set by MAC hardware,
it is hardware's logic, so fix it in ath10k will be more convenient.
log:
ath10k_sdio mmc1:0001:1: Got RX ind from invalid peer: 65535
