Lies!  :-)

This is based off one of the kvmarm.git topic branches (I didn't bother to figure
out which one), not v6.5-rc1.

Please try to incorporate git format-patch's "--base" option into your workflow,
e.g. I do "git format-patch --base=HEAD~$nr" where $nr is the number of patches
I am posting.

It's not foolproof, e.g. my approach doesn't help if I have a local patch that
I'm not posting, but 99% of the time it Just Works and eliminates any ambuitity.

You can also do "--base=auto", but that only does the right thing if your series
has its upstream branch set to the base/tree that you want your patches applied
to (I use the upstream branch for a completely different purpose for my dev branches).
