Subject: [PATCH -tip v3 0/4] x86,mm/pat: Move towards using generic interval tree
Date: Wed, 20 Nov 2019 17:15:57 -0800	[thread overview]
Message-ID: <20191121011601.20611-1-dave@stgolabs.net> (raw)

Changes from v2:
 - Removed unnecessary goto error path in patch 1, per tglx.
 - Added the corresponding Makefile change for patch 4, per mingo.
 - Added tglx's review tags.

Changes from v1[0]:
 - Got rid of more code in patch 1 by using the end - 1 for closed
   intervals, instead of keeping the overlap-check.
   
 - added an additional cleanup patch.

Hi,

I'm sending this series again in this format as the interval tree
node conversion will, at a minimum, take longer than hoped for
(ie: Jason still removing interval tree users for the mmu_notifier
rework[1]). There is also a chance this will never see be done.

As such, I'm resending this series (where patch 1 is the only
interesting one and which Ingo acked previously, with the exception
that the nodes remain fully closed). In the future, it would be
trivial to port pat tree to semi open nodes, but for now think that
it makes sense to just get the pat changes in.

Please consider for v5.5. Thanks!
