### Linux Kernel
ALHP provides patched kernels (except `linux-zen`) that build with `-march=x86-64-vN`. Thanks to
[graysky](https://github.com/graysky2) for providing [these patches](https://github.com/graysky2/kernel_compiler_patch).
### Directly linked kernel modules
**Above-mentioned patching breaks all directly linked modules** like `nvidia` (not `nvidia-dkms`) or
`virtualbox-host-modules-arch` (not `virtualbox-host-dkms`). Their respective `dkms`-variant is not affected. This issue
is being tracked in #68, a solution is being worked on.
