Subject: [PATCH v4 0/2] [PATCH v2 0/6] sparsemem support for RISC-V
Date: Wed, 9 Jan 2019 13:39:09 -0700 [thread overview]
Message-ID: <20190109203911.7887-1-logang@deltatee.com> (raw)
This patchset implements sparsemem on RISC-V. The first couple patches
from the previous version have been merged into v4.20 and the ARM patches
have been sent separately to the ARM maintainers. These are the RISC-V
patches only.
This is the first small step in supporting P2P on RISC-V.

Changes in v4:
* Rebased onto v5.0-rc1
* Changed the SECTION_SIZE_BITS to 27, per Nick Kossifidis
Changes in v3 (only sent the common patches):
* Rebased on v4.20-rc1
* Minor fixups
* Collected Ack from Will Deacon
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.
