| |
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.
-- Logan Gunthorpe (6): 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 RISC-V: Implement sparsemem
