The 2nd patch (8002) has a single patch. This one posted by Ard Biesheuvel ard.biesheuvel@linaro.org is needed in order to resolve the following issue found in our tests.

[ 2.843717] pci 0007:02:00.0: BAR 0: failed to claim resource for efifb!

Please let me know if you have any comments or need anything else in order to get them ported for CentOS 7.4 GA.
