Sorry for the late reply. Locally I have this patchset on top of linus/master and a patchset that added add_reservation_in_range.
But, this patchset can be rebased on top of this commit with 'minimal' merge conflicts:
commit c1ca56bab12f3 (tag: v5.4-rc7-mmots-2019-11-15-18-40, github-akpm/master) Author: Linus Torvalds <torvalds@linux-foundation.org>
pci: test for unexpectedly disabled bridges
It's the latest mmotm I find on https://github.com/hnaz/linux-mm.git. My next patchset will be rebased on top mmotm.
