    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.
