In order to be able to use primitives such as vcpu_mode_is_32bit(), we need to synchronize the guest PSTATE. However, this is currently done deep into the bowels of the world-switch code, and we do have helpers evaluating this much earlier (__vgic_v3_perform_cpuif_access and handle_aarch32_guest, for example). Move the saving of the guest pstate into the early fixups, which cures the first issue. The second one will be addressed separately.

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.
