for now, we just count how mayn pages we missed an advisory on,
those all effectively are "wired". If we're fast enough on registering,
it turns out we actually miss nothing.
DUe to https://github.com/rust-lang/rust/issues/114447 direct access to
static mut variables causes a warning which will be turned into an
error in the 2024 edition.
The workaround is to use `addr_of!()` and `addr_of_mut!()` macros and
then dereference that.

With Rust 1.76.0, we no longer support building with `#![no_std]` or
`panic = "abort"`, both of which are required within the kernel. As a
workaround, go back to building the kernel under
`riscv32imac-unknown-none-elf`.

Support passing process arguments in register 2 as part of arguments to
a process.
This requires updating the `InitialProcess` struct that is received from
the loader, and so requires modeifications to be made in tandem.

these are just sync'd to the asm.S and checked in.
Eventually, we should migrate that .S file into using
in-line assembly macros, but now that I look at it, I remember
why it hasn't been done yet -- there are some fancy conditionals
used to enable compatibility with different architectures that
I don't know off the top of my head how to translate into
in-line assembly syntax.
a lot of re-import warnings have cropped up. While I appreciate
their studiousness on this, the problem is that removing some
of these exports in the API crate could mean that future users
who want access to some API features that aren't used in this
configuration are now unaccessible.
I think it's not a huge problem at the moment, just spam-cleaning
the warnings because there are too many to deal with carefully
at the moment.
When enumerating processes, the `find_process()` process didn't consult
whether a process was actually free. This resulted in a crash,
particularly when attaching a debugger to a crashed process.

This command ensures memory is all owned by the correct process and is
unique in its ownership.
It takes a long time to run, so ensure the watchdog timer is disabled.

Add a function to ensure mappings are unique across the whole system.
This takes a very long time and can crash if the watchdog timer isn't
paused.
