Subject[PATCHSET x86/numa] x86-64, NUMA: bring sanity to NUMA emulation
Date
Hello,

NUMA emulation is quite convoluted involving unnecessary mapping and
reverse mapping between apicids, PXMs, nodes and memory addresses.
This patchset tries to restore some sanity to the whole thing.

Tested on an opteron NUMA machine which can do both ACPI and AMD
configs. All NUMA configs, emulations, !NUMA and UP work as expected.

This patchset is on top of tip/x86/numa[1] +
bring-sanity-to-NUMA-configuration patchset[2] and contains the
following 7 patches.

0001-x86-64-NUMA-Trivial-changes-to-prepare-for-emulation.patch
0002-x86-64-NUMA-Build-and-use-direct-emulated-nid-phys-n.patch
0003-x86-64-NUMA-Make-emulation-code-build-numa_meminfo-a.patch
0004-x86-64-NUMA-Wrap-node-ID-during-emulation.patch
0005-x86-64-NUMA-Emulate-directly-from-numa_meminfo.patch
0006-x86-64-NUMA-Unify-emulated-apicid-node-mapping-trans.patch
0007-x86-64-NUMA-Unify-emulated-distance-mapping.patch

The patchset is available in the following git branch.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git x86_64-numa-emu-unify

Diffstat follows.
