Hi Greg, 

6.1.23-rc2 is failing to boot on x86 WSL. A bisect leads to commit
c2f05366b687 ("swiotlb: fix slot alignment checks") being the problem
and reverting this patch puts everything back in a working state.

There's a report from Dexuan who also encountered this error on a Linux
VM on Hyper-V:

https://lore.kernel.org/all/CAA42JLa1y9jJ7BgQvXeUYQh-K2mDNHd2BYZ4iZUz33r5zY7oAQ@mail.gmail.com/

Adding a chunk of my log below which shows errors occuring from the hv_strvsc driver.

+cc Dexuan, Petr, Tyler, Hyper-V list, swiotlb list and maintainers
