grub2/0219-Measure-kernel-and-initrd-on-BIOS-systems.patch
Javier Martinez Canillas db7cf3a089
More fixes for BLS
Add some fixes for BLS parsing logic and also make 20-grub.install script
to query the relative path of the kernel and initramfs images, so BLS can
also work when /boot is not a mount point or is a btrfs subvolume.

Also pull some build fixes.

Resolves: rhbz#1588184
