-Subject: [PATCH 2/2] xen/arm: Correctly report the memory region in the dummy
- NUMA helpers
-
-NUMA is currently not supported on Arm. Because common code is
-NUMA-aware, dummy helpers are instead provided to expose a single node.
-
-Those helpers are for instance used to know the region to scrub.
-
-However the memory region is not reported correctly. Indeed, the
-frametable may not be at the beginning of the memory and there might be
-multiple memory banks. This will lead to not scrub some part of the
-memory.
-
-The memory information can be found using:
-    * first_valid_mfn as the start of the memory
-    * max_page - first_valid_mfn as the spanned pages
-
-Note that first_valid_mfn is now been exported. The prototype has been
-added in asm-arm/numa.h and not in a common header because I would
-expect the variable to become static once NUMA is fully supported on
-Arm.
-
