Sure, sounds good to me!

Why was this PR closed? Couldn't we just have switched the target branch to `main`?

Thanks!

Heyyyyy

Related to #74

This only occurs when using rsdp `2.0.0` and seems to be fixed by rsdp `2.0.1`. I've tracked the fix down to this commit: https://github.com/rust-osdev/acpi/commit/a0db984096d49a499117760f913ea86ce5e9b604, but I'm not entirely sure why...

I can still reproduce this on `1.78.0-nightly` (tested with 090f0309fb41c2ff19b1a79b5567cecc3ca084df).

Can you elaborate on why the compiler would be allowed to optimize out the non-volatile read?
