Subject: [PATCH v2 0/6] sparsemem support for RISC-V
Date: Mon, 15 Oct 2018 11:56:56 -0600 [thread overview]
Message-ID: <20181015175702.9036-1-logang@deltatee.com> (raw)
Message-ID: <20181015175656.WYiAEsJQm-h2WnCZcwHjmIMeC5Ak_WZu5Mgh1vJXjWw@z> (raw)
This patchset implements sparsemem on RISC-V. The first few patches
move some code in existing architectures into common helpers
so they can be used by the new RISC-V implementation. The final
patch actually adds sparsmem support to RISC-V.
This is the first small step in supporting P2P on RISC-V.

Changes in v2:
* Rebase on v4.19-rc8
* Move the STRUCT_PAGE_MAX_SHIFT define into a common header (near
the definition of struct page). As suggested by Christoph.
* Clean up the unnecessary nid variable in the memblocks_present()
function, per Christoph.
* Collected tags from Palmer and Catalin.

mm: Introduce common STRUCT_PAGE_MAX_SHIFT define
mm/sparse: add common helper to mark all memblocks present
ARM: mm: make use of new memblocks_present() helper
arm64: mm: make use of new memblocks_present() helper
sh: mm: make use of new memblocks_present() helper
