Rebased to Linus' master branch at commit 1d6da87a3241 ("Merge branch
'drm-next' of git://people.freedesktop.org/~airlied/linux")
ACPI 5.1 already introduced NUMA support for ARM64, which can get the
NUMA domain information from SRAT and SLIT table, so parse those two
tables to get mappings from cpu/mem to numa node configuration and
system locality.
v7 updates:
- Rebased to resolve one merge conflict.
- New patch 13/15 to enable use of existing MADT parsing code instead
of adding an additional implementation of the parser.
- Added some Acked-by headers to patches in arm64 arch directories.
v6 updates:
- Changed message printed in 13/14 to omit meaningless "cpu"
number. (noted by Dennis Chen and Hanjun Guo)
- New patch 7/14 to print different messages for NUMA disabled case.
(noted by Dennis Chen)
- Squashed two patches into 14/14.
- Added Reviewed-by to 4/14
v5 updates:
- Fixed ia64 build failure by gating some unused functions with #if
CONFIG_{X86,ARM64}.
- Fixed section mismatch errors for X86 case.
- Removed unneeded #include from some files.
- Tested to build cleanly on ARM64, X86_64, IA64
v4 updates:
- Updated from Hanjun Guo's v3 patches.
- Rebased on top of v16 of device-tree NUMA patches.
- Reordered some of the changes so that we don't introduce code and
then change it several times in the patch set. New code is
introduced in its final form. Code reused from x86 is first moved
with no change, and then a separate patch to make any needed
changes.
- code that is used only by ia64, moved to architecture specific
files.
v3 updates:
- Deep investigation about the ACPI_DEBUG_PRINT() and remvoe
that for acpi/numa.c (patch 2/12)
- Remove the duplicate NULL check for table print (patch 3/12)
- Introduce CONFIG_ACPI_HAS_NUMA_ARCH_FIXUP to remove duplicate
dummy function for acpi_numa_arch_fixup()
- Solve the problem that the mapping from logical cpu to numa node
is wrong which spotted out by Lorenzo
- cleanups for x86 and move acpi_numa_slit_init() and some other
functions to common place, then reduce the duplicate of x86
and arm64 (patch 7-12/12).
- rebased on top of 4.4 and Ganapat's v9 patch set.
