[RFC PATCH 0/5] Add support for memmap on memory feature on ppc64

This patch series update memmap on memory feature to fall back to memmap allocation outside the memory block if the alignment rules are not met. This makes the feature more useful on architectures like ppc64 where alignment rules are different with 64K page size. This patch series is dependent on

[RFC PATCH 1/5] mm/hotplug: Embed vmem_altmap details in memory block

With memmap on memory, some architecture needs more details w.r.t altmap such as base_pfn, end_pfn, etc to unmap vmemmap memory. Embed vmem_altmap data structure to memory_bock and use that instead of nr_vmemmap_pages. On memory unplug, if the kernel finds any memory block in the range to be usin

[RFC PATCH 2/5] mm/hotplug: Allow architecture override for memmap on memory feature

Some architectures like ppc64 wants to enable this feature only with radix translation and their vemmap mappings have different alignment requirements. Add overrider for mhp_supports_memmap_on_memory() and also use altmap.reserve feature to adjust the pageblock alignment requirement. The patch als

[RFC PATCH 3/5] mm/hotplug: Simplify the handling of MHP_MEMMAP_ON_MEMORY flag

Instead of checking for memmap on memory feature enablement within the functions checking for alignment, use the kernel parameter to control the memory hotplug flags. The generic kernel now enables memmap on memory feature if the hotplug flag request for the same. The ACPI code now can pass the fl

Radix vmemmap mapping can map things correctly at the PMD level or PTE level based on different device boundary checks. We also use altmap.reserve feature to align things correctly at pageblock granularity. We can end up loosing some pages in memory with this. For ex: with 256MB memory block size,
