WMI RX workqueue is created with WQ_MEM_RECLAIM flag. When host receives
the WMI service ready event it queues the work. There is 50sec delay in
scheduling workqueue to process WMI service ready event. This results in
host timeout (timeout = 15sec) and wifi load failure. This cleans up the
host data structures related to data path. But work got scheduled after
50sec resulting in init path handling with inconsistent data structures.
Use workqueue UNBOUND flag to create WMI RX workqueue. Works queued to
unbound workqueues are implicitly HIGHPRI and dispatched to unbound
workers as soon as resources are available.

Currently qdf_mem contains a function, qdf_mem_validate_list_node(), for
validating a list node and ensuring it is currently part of a list.
Instead, abstract this function from qdf_mem, and move the definition to
qdf_list_node_in_any_list() in qdf_list. This is a more reasonable
location for the list-specific logic, and allows its reuse by other
callers.

Currently, qdf_nbuf_map_check_for_leaks() logs the leak information
under spinlock before inducing a panic. This can cause a confusing false
positive panic upon releasing the spinlock if the logging took longer
than the spinlock timeout threshold. Since we already know we are going
to panic, panic under spinlock to ensure the panic message is always
appropriate.

ring_base_align. If not, it frees the memory and re-allocates by adding
7 bytes to alloc_size and returns aligned address to the caller.

Currently, the QDF debugfs feature returns a no-support error code for
the init call when the feature is compiled out. Instead, return success
to avoid wlan load failure on some configurations and to make error
checking by the caller more straight forward under all configurations.
The deinit call also has the same problem, but none of the callers pay
attention to the return status. Additionally, the deinit function
returns success unconditionally when the feature is compiled in.
Rather than changing the return status to success when the feature is
compiled out, change the return type of the deinit function to void.

Currently mtrace messages are getting recorded in circular
queue but are not getting used for DIAG Infrastructure.
Add support to print the mtrace messages on DIAG infrastructure in
format such that there will be two 32 bit fields printed on the
logs. These two fields will be constructed as explained below:
1. First field will be constructed using below bit positions:
a. Bit 0 – 14 ( 15 Bits Lsb ) will contain the messageIDs
b. The bit 15-22 will represent the destination module,
and the 23-30 will represent the source module which is
initiating the message.
c. Bit 31 will represent whether the message is from host
or from FW. If bit is 0, it indicates the message is
from host and if it is 1 it indicates the message is
from FW.
2. Second field will be constructed using below bit positions:
a. First 16 bits (From LSB )will be used for counter.
b. Next 8 bits would be the vdev id.
c. Remaining 8 bits are reserved for future use.
Here counter is static unsigned 16 bit value which will be
used to keep track of number of logs given to QXDM and out of
these logs how many logs have been missed.
