Linux kernel source tree

Currently entry_64_compat is exempt from objtool, but with vmlinux mode there is no hiding it. Make the following changes to make it pass: - change entry_SYSENTER_compat to STT_NOTYPE; it's not a function and doesn't have function type stack setup. - mark all STT_NOTYPE symbols with UNWIND_HINT_EMPTY; so we do validate them and don't treat them as unreachable. - don't abuse RSP as a temp register, this confuses objtool mightily as it (rightfully) thinks we're doing unspeakable things to 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.
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.
