We must always use GUEST_ADDR_MAX, because even 32-bit hosts can
use -R to restrict the memory address of the guest.

These constants are only ever used with access_ok, and friends.
Rather than translating them to PAGE_* bits, let them equal
the PAGE_* bits to begin.

This function is a copy of the code out of qemu_rdma_registration_stop;
with some of the comments removed.
It's OK to split this code out so you can use it

This introduces a base class for tests that need to interact with a
Linux guest. It generalizes the "boot_linux.py" code, already been
used by the "virtiofs_submounts.py" and also SSH related code being
used by that and "linux_ssh_mips_malta.py".
While at it, a number of fixes on hopeful

Just had the one comment on patch 4, which is really no big deal. I need
to integrate tooling and/or kernel support in order to properly test
this, but just from code inspection, I think it's good.

This is basically the infrastructure around "boot_linux.py" tests, but
now made into a base class for general use.

This data can be allocated by page_alloc_target_data() and

This data will be used to hold tag memory for AArch64 MTE.

Return bool not int; pass abi_ulong not 'unsigned long'.
All callers use abi_ulong already, so the change in type
has no effect.

This is intende to be replaced by a bump to Avocado 85.0, to be
released by Feb 8 2021.
Latest master contains an improvement to "avocado.utils.vmimage" that
let's it download older Fedora images from the archive locations.
That allows the currently set Fedora 31 images to continue being used.
