[PATCH v4 11/13] mm: support section-unaligned ZONE_DEVICE memory ranges

The initial motivation for this change is persistent memory platforms that, unfortunately, align the pmem range on a boundary less than a full section (64M vs 128M), and may change the alignment from one boot to the next. A secondary motivation is the arrival of prospective ZONE_DEVICE users that w

[PATCH v4 08/13] x86, kasan: clarify kasan's dependency on vmemmap_populate_hugepages()

Historically kasan has not been careful about whether vmemmap_populate() internally allocates a section worth of memmap even if the parameters call for less. For example, a request to shadow map a single page results in a full section (128MB) that contains that page being mapped. Also, kasan has n

[PATCH v4 13/13] libnvdimm, pfn, dax: stop padding pmem namespaces to section alignment

Now that the mm core supports section-unaligned hotplug of ZONE_DEVICE memory, we no longer need to add padding at pfn/dax device creation time. The kernel will still honor padding established by older kernels. Cc: Toshi Kani Signed-off-by: Dan Williams --- drivers/nvdimm/pfn_devs.c | 42
