Strange, I just did a test using the patches I received via the kexec 
mailing list, and git am applied them cleanly on v4.8-rc1.

No, they apply directly on v4.8-rc1.

I just published a branch with the patches, if you want you can use that 
instead. The branch is called kexec-patches and is at the repo
