The patch titled
Subject: mm/hmm: kconfig split HMM address space mirroring from device memory
has been removed from the -mm tree. Its filename was
mm-hmm-kconfig-split-hmm-address-space-mirroring-from-device-memory.patch
This patch was dropped because it was withdrawn
------------------------------------------------------
From: Jérôme Glisse <jglisse@xxxxxxxxxx>
Subject: mm/hmm: kconfig split HMM address space mirroring from device memory
To allow building device driver that only care about address space
mirroring (like RDMA ODP) on platform that do not have all the pre-
requisite for HMM device memory (like ZONE_DEVICE on ARM) split the
HMM_MIRROR option dependency from the HMM_DEVICE dependency.
