[PATCH v3 1/5] mm,memory_hotplug: Introduce MHP_MEMMAP_ON_MEMORY

This patch introduces MHP_MEMMAP_ON_MEMORY flag, and prepares the callers that add memory to take a "flags" parameter. This "flags" parameter will be evaluated later on in Patch#3 to init mhp_restrictions struct. The callers are: add_memory __add_memory add_memory_resource Unfortunately, we do

[PATCH v3 3/5] mm,sparse: Add SECTION_USE_VMEMMAP flag

When hot-removing memory, we need to be careful about two things: 1) Memory range must be memory_block aligned. This is what check_hotplug_memory_range() checks for. 2) If a range was hot-added using MHP_MEMMAP_ON_MEMORY, we need to check whether the caller is removing memory with the same

[PATCH v3 0/5] Allocate memmap from hotadded memory

[PATCH v3 4/5] mm,memory_hotplug: Allocate memmap from the added memory range for sparse-vmemmap

Physical memory hotadd has to allocate a memmap (struct page array) for the newly added memory section. Currently, alloc_pages_node() is used for those allocations. This has some disadvantages: a) an existing memory is consumed for that purpose (~2MB per 128MB memory section on x86_64) b)

[PATCH v3 5/5] mm,memory_hotplug: Allow userspace to enable/disable vmemmap

It seems that we have some users out there that want to expose all hotpluggable memory to userspace, so this implements a toggling mechanism for those users who want to disable it. By default, vmemmap pages mechanism is enabled. Signed-off-by: Oscar Salvador --- drivers/base/memory.c

[PATCH v3 2/5] mm: Introduce a new Vmemmap page-type

This patch introduces a new Vmemmap page-type. It also introduces some functions to ease the handling of vmemmap pages: - vmemmap_nr_sections: Returns the number of sections that used vmemmap. - vmemmap_nr_pages: Allows us to retrieve the amount of vmemmap pages derivated from any
