Mark instructions that use pointers to areas in the stack outside of the current stack frame, and process them accordingly in mem_op_stack(). This way, we also support BPF-to-BPF calls where the caller passes a pointer to data in its own stack frame to the callee (typically, when the caller passes an address to one of its local variables located in the stack, as an argument). Thanks to Jakub and Jiong for figuring out how to deal with this case, I just had to turn their email discussion into this patch.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
