For cases where you want to create and immediately start a thread, the
Linux kernel has the kthread_run() API. Create a QDF wrapper for
kthread_run() as well as companion APIs for waiting for a thread to exit
and one to check if the current thread should exit.

To convert ASCII hexa decimal character to unsigned value and similarly
to convert string of ASCII hexa decimal characters to array of decimal
values, there is need of QDF API.
Therfore, add QDF wrapper functions to kernel API hex_to_bin() and
hex2bin().

There is an invalid circular dependency of header files in the
driver. qdf_nbuf.h file includes itself as qdf_nbuf.h file
includes i_qdf_nbuf.h and i_qdf_nbuf.h again includes qdf_nbuf.h.
To resolve this issue, do not include qdf_nbuf.h in i_qdf_nbuf.h

It is generally useful to log the reason for a panic at the time of

kcompactd consumes many CPU cycles without being successful
to make high-order page. One of the reason is WIFI driver is
allocating order-3 page a lot.
It shows 46% high-order allocation comes from WIFI driver.
Of course, it should be fixed in MM layer but it is never
easy stuff to fix in near future.
Regardless of MM changes, drivers should do best effort to reduce
high-order allocation, too.
This patch fixes the problem via not waking kcompactd.

In case where a qdf event was waiting and an SSR has occurred,
force_set flag is set for the event. After driver recovery is
complete the same event can be reset and re-used without
resetting this flag. This may cause a failure even after the
event was successfully completed.

As WIN has multiple modules and QDF is the last one to be unloaded,
QDF is crashing when it tried to print the file name of an nbuf
allocated by other modules. To fix this, copy the file name in the
QDF nbuf tracker, rather than using the pointer to file name,
to avoid access to the invalid pointer.

Netlink service init and exit is invoked as part of wlan logging
init and exit during qdf module init and exit. This brings in a
hard dependency to enable and compile wlan logging service
even if not used.
Decouple netlink service and wlan logging service to remove
inter-dependency. WIN qdf module currently does not require wlan
logging to be enabled. This separation leads to bss savings in qdf
module.
