[PATCH v2 0/2] hyperv: Move some features to common code

From: Nuno Das Neves
Date: Wed Jan 22 2025 - 20:50:15 EST


There are several bits of Hyper-V-related code that today live in
arch/x86 but are not really specific to x86_64 and will work on arm64
too.

Some of these will be needed in the upcoming mshv driver code (for
Linux as root partition on Hyper-V). So this is a good time to move
them to drivers/hv.
