An earlier patch I sent reduced the stack usage enough to get below the warning limit, and I could show this was safe, but with GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, it gets worse again because large stack variables in the same function no longer overlap: drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'translate_scan.isra.2': drivers/staging/rtl8712/rtl871x_ioctl_linux.c:322:1: error: the frame size of 1200 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Split out the largest two blocks in the affected function into two separate functions and mark those noinline_for_stack.

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.
