The 56 reverts (then re-applys) make sense in the context of "replace
this whole huge patch set with a slightly different whole huge patch
set", but may be confusing to somebody looking at the patches individually.
The individual reverts do not mention why they're being reverted...

bbf4ccd x86/efi: Fix boot failure with EFI stub
28b55e2 Revert "x86/efi: Fix boot failure with EFI stub"
d3788cd x86/efi: Fix boot failure with EFI stub

633a14b x86/efi: Fix off-by-one bug in EFI Boot Services reservation
adcd8d0 Revert "x86/efi: Fix off-by-one bug in EFI Boot Services reservation"
965918e x86/efi: Fix off-by-one bug in EFI Boot Services reservation

So ... How about?:

Squash all of the 56 reverts into one commit titled e.g. "UBUNTU: SAUCE:
Back out UEFI secure boot changes to prepare for replacement", with a
paragraph explaining why.  (Don't squash the re-applys).
