That’s fine. It wasn’t very clear to me in maintainer-tip.rst.

I checked a few older commits, and the placement seems mixed—some have it
at the end, but it’s not very consistent. I can update my patches
accordingly and apply the same change across all of them.


 The ABMC feature details are documented in APM [1] available from [2].
 [1] AMD64 Architecture Programmer's Manual Volume 2: System Programming
 Publication # 24593 Revision 3.41 section 19.3.3.3 Assignable Bandwidth
 Monitoring (ABMC).

I’ve been basing the patches on top of:
git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
with `origin/HEAD -> origin/master`.

Please let me know if this is the correct branch to use to make the merge
process easier.
