Interrupt handlers do not have valid process context and hence
current pointer is not valid for software/hardware interrupt
handlers. In WLAN log to user space API current process name is
logged using current->comm but hardware/software interrupts do not
have corresponding current pointer because they use current pointer
of interrupted process. Make changes to not to log process name when
log message is generated from hardware/software interrupt handlers.

qcacld-2.0 to qcacld-3.0 propagation
Observed kernel panic due to the race between initialization of
logging wait_queue in supplicant thread context and the same
uninitialized wait_queue is referenced in MCThread context.
To mitigate this issue, don't send logs to upper layers if logging
service is not initialized.

qcacld-2.0 to qcacld-3.0 propagation.
As there are a lot of prints dropped on the console in
short duration, it leads to interrupt disablement on
the cpu.
So reducing the logging level of log statement from
ERROR to INFO

qcacld-2.0 to qcacld-3.0 propagation
wlan_queue_logmsg_for_app is called while holding spin lock with
interrupts disabled. It may call pr_info to log if node is dropped
while sending to user space.
This may cause interrupts disabled for some time.
As part of fix remove all pr_info from wlan_queue_logmsg_for_app.

qcacld-2.0 to qcacld-3.0 propagation
CONFIG_CNSS_LOGGER is introduced to move the logging feature from
CLD driver to kernel module.
This change will mainly benefit for two things for CLD driver.
- To support for dual wifi driver instances and also
future plan of moving out the logging thread and buffer
management to the kernel module.
- While debugging the critical feature that triggers the
autoshutdown and SSR, the log buffer in the CLD driver will
be lost after the driver restart or unload.
The CLD driver will register itself to the cnss logging module and
get the radio index as the indentification for rest of the operation.
Also the message sent from CLD driver to usespace need to be packed with
struct tAniNlHdr; and the hddctx.radio_index need to be filled along with
the message, so that usespace can differentiate the message.

Change to initiate BUG report in case of fatal event
Add INI support to Enable/Disable it.
The fatal event handled are as below:
- Roaming failed after successful preauth.
- SME command timeout.
- PE defer queue is full.
- CDS run out of message wrapper.
- HDD level wait for event timeout.

We already know kernel version is more than equal to 3.10.
So remove static checks for any previous kernel.

This is qcacld-2.0 to qcacld-3.0 propagation
Avoid invoking vfree inside spinlock during logging service
activation and deactivation. Since vfree is prone to sleep, this
disables the IRQs for duration longer than the acceptable limit.
vfree can be done without spin lock here, as there is no
synchronization issue in this scenario.
