This series enables vmemmap backing memory allocation from device memory ranges on arm64. But before that, it enables vmemmap_populate_basepages() and vmemmap_alloc_block_buf() to accommodate struct vmem_altmap based alocation requests. This series applies on 5.8-rc1. Pending Question: altmap_alloc_block_buf() does not have any other remaining users in the tree after this change. Should it be converted into a static function and it's declaration be dropped from the header (include/linux/mm.h). Avoided doing so because I was not sure if there are any off-tree users or not.Well, off-tree users probably have an active fork anyway so they could switch to vmemmap_alloc_block_buf()...
Sure, will make the function a static and remove it's declaration from the header.
Regardless, can you please update Documentation/vm/memory-model.rst to keep it in sync with the code?
Sure, will do.
