| |
This series enables vmemmap backing memory allocation from device memory ranges on arm64. But before that, it enables vmemmap_populate_basepages() to accommodate struct vmem_altmap based requests.
This series applies after latest (v12) arm64 memory hot remove series (https://lkml.org/lkml/2020/1/16/46) on Linux 5.5-rc7.
Changes in V1:
- Added an WARN_ON() in unmap_hotplug_range() when altmap is provided without the page table backing memory being freed
Changes in RFC V2: (https://lkml.org/lkml/2019/10/21/11)
- Changed the commit message on 1/2 patch per Will - Changed the commit message on 2/2 patch as well - Rebased on arm64 memory hot remove series (v10)
RFC V1: (https://lkml.org/lkml/2019/6/28/32)
