grub2/0166-Make-grub_strtoul-end-pointer-have-the-right-constif.patch
Javier Martinez Canillas 7e98da058f
Cleanup our patchset to reduce the number of patches 
This change reorganizes and cleanups our patches to reduce the patch number
from 314 patches to 187. That's achieved by dropping patches that are later
reverted and squashing fixes for earlier patches that introduced features.

There are no code changes and the diff with upstream is the same before and
after the cleanup. Having fewer patches makes easier to manage the patchset
and also will ease to rebase them on top of the latest grub-2.04 release.
