[PATCH V3 (RESEND) 0/3] arm64: Enable vmemmap mapping from device memory

2020-06-17 Thread Anshuman Khandual
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:
