As a heads-up, I generated the diff with git format-patch -D, to omit
the preimage for those ~5000 lines being deleted. Unfortunately, git-am
will refuse to apply that, with something like:
| error: removal patch leaves file contents
| error: include/asm-generic/atomic-instrumented.h: patch does not apply
I've pushed the patch to my atomics/regenerate branch [1] for now. I can resend
with the full context (or leaving the stale files for a subsequent deletion),
if that's preferable?
Thanks,
Mark.
