Subject: [PATCH 0/6] PCI: leak fixes, removable generic PCI host, assorted stuff
Date: Tue, 24 Apr 2018 17:13:36 +0200	[thread overview]
Message-ID: <cover.1524582822.git.jan.kiszka@siemens.com> (raw)

This primarily enables to unbind the generic PCI host controller without
leaving lots of memory leaks behind. A previous proposal patch 5 was
rejected because of those issues [1].

The fixes have been validated in the Jailhouse setup, where we add and
remove a virtual PCI host controller on hypervisor activation/
deactivation, with the help of kmemleak.

Besides that, there is tiny PCI API cleanup at the beginning and
support for manually enabled PCI domains at the end that enables the
Jailhouse scenario.
