Subject[PATCH v2 0/2] Introduce common code for risc-v sparsemem support
These are the first two common patches in my series to introduce
sparsemem support to RISC-V. The full series was posted last cycle
here [1] and the latest version can be found here [2].

As recommended by Palmer, I'd like to get the changes to common code
merged and then I will pursue the cleanups in the individual arches (arm,
arm64, and sh) as well as add the new feature to riscv.

I would suggest we merge these two patches through Andrew's mm tree.



[2] riscv-sparsemem-v4


Changes in v2:
* Added a comment documenting the awkwardly named memblocks_present()
function, as suggested by Andrew.


Logan Gunthorpe (2):
mm: Introduce common STRUCT_PAGE_MAX_SHIFT define
mm/sparse: add common helper to mark all memblocks present
