[ Upstream commit38792972de] The recent switch on arm64 from DYNAMIC_FTRACE_WITH_REGS to DYNAMIC_FTRACE_WITH_ARGS failed to take into account that we currently require the former in order to allow the function graph tracer to be enabled in combination with shadow call stacks. This means that this is no longer permitted at all, in spite of the fact that either flavour of ftrace works perfectly fine in this combination. So permit WITH_ARGS as well as WITH_REGS.

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.
