Access the eBPF scratch space using the frame pointer rather than our stack pointer, as the offsets from the ARM frame pointer are constant across all eBPF programs. Since we no longer reference the scratch space registers from the stack pointer, this simplifies emit_push_r64() as it no longer needs to know how many words are pushed onto the 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.
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.
