No, I'm saying I don't want to waste a bunch of time tracking down exactly which
commit a 36 patch series is based on. E.g. I just refreshed tip/master and still
get:
Applying: x86/idtentry: Incorporate definitions/declarations of the FRED external interrupt handler type
error: sha1 information is lacking or useless (arch/x86/include/asm/idtentry.h).
error: could not build fake ancestor
Patch failed at 0024 x86/idtentry: Incorporate definitions/declarations of the FRED external interrupt handler type
hint: Use 'git am --show-current-patch=diff' to see the failed patch

Yes, lore also appears to be missing patches. I grabbed the mbox off of KVM's
patchwork instance.
