Use str.split() or str.partition() and only keep the first part:
>>> text = """The registers rax, rcx and rdx are touched when controlling
IBRS
... so they need to be saved when they can't be clobbered.
...
... diff --git a/arch/x86/entry/calling.h b/arch/x86/entry/calling.h
... index 45a63e0..3b9b238 100644
... """
>>> cleaned_text = text.partition("diff --git")[0].strip()
>>> print(cleaned_text)
The registers rax, rcx and rdx are touched when controlling IBRS
so they need to be saved when they can't be clobbered.
