[PATCH v19 0/5] SpinLockIrq for rust

This is the latest patch series for adding rust bindings for controlling
local processor interrupts, adding support for spinlocks in rust that
are acquired with local processor interrupts disabled, and implementing
local interrupt controls through refcounting in the kernel.

The previous version of this patch series can be found here:

https://lore.kernel.org/all/20260205204709.528234-1-lyude@redhat.com/

This patch series applies on top of boqun's rust-sync branch:

https://git.kernel.org/pub/scm/linux/kernel/git/boqun/linux.git/?h=rust-sync

Now that we've gotten the C-side of these changes in, this patch series
is now exclusively concerned with the rust side of these changes. For
more information on how we came to the design for the C side of the API,
see the explanation in the previous version of the patch series.
