Read FW backtrace entry through FW reserved payload engine, and then add FW backtrace dump during SER (system error recover) L2 reset process. It contains a list of RA (return address) and SP (stack pointer) which gives us a chance to trace back the call stack of FW. Moreover, if core dump might have wrong content due to error during dumping, we won't invoke device core dump framework. For this case, rtw89_ser_cd_free() is added to free buffer by ourselves.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
