The commits will show up in

https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next

Probably today or tomorrow.  You'll have to build your own kernel for 
now.  The typical path would be these patches make it into 4.15 (if that 
window is still open) and then eventually be released as part of 4.15 
and then the older tree maintainers can cherry-pick things into their trees.

Getting into a distro kernel depends on the distro I imagine.  Might be 
able to file a bug with the Fedora bug tracker for the kernel and then 
we can co-ordinate getting the patches into their tree.
