Subject: [PATCH 0/5] mm: rework hmm to use devm_memremap_pages
Date: Mon, 21 May 2018 15:35:14 -0700	[thread overview]
Message-ID: <152694211402.5484.2277538346144115181.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

Hi Andrew, please consider this series for 4.18.

For maintainability, as ZONE_DEVICE continues to attract new users,
it is useful to keep all users consolidated on devm_memremap_pages() as
the interface for create "device pages".

The devm_memremap_pages() implementation was recently reworked to make
it more generic for arbitrary users, like the proposed peer-to-peer
PCI-E enabling. HMM pre-dated this rework and opted to duplicate
devm_memremap_pages() as hmm_devmem_pages_create().

Rework HMM to be a consumer of devm_memremap_pages() directly and fix up
the licensing on the exports given the deep dependencies on the mm.

Patches based on v4.17-rc6 where there are no upstream consumers of the
HMM functionality.
