mainlining shenanigans
76f4e2da45
Currently machine_kexec() doesn't reset to EL2 in the case of a crashdump kernel. This leaves potentially dodgy state active at EL2, and means that if the crashdump kernel attempts to online secondary CPUs, these will be booted as mismatched ELs. Let's reset to EL2, as we do in all other cases, and simplify things. If EL2 state is corrupt, things are already sufficiently bad that kdump is unlikely to work, and it's best-effort regardless.

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.
