    Subject[PATCH v2 0/9] CPU enable method based SMP/hotplug + MSM conversion
    Date
    This is a rework of patches sent a months back by Rohit[1].
    The goal of these patches is to add support for SMP and (basic)
    hotplug on MSM based SoCs. To get there, we add support for a
    generic way to hook in SMP/hotplug support code based on DT. To
    show how it's used, we convert the MSM8660 SMP support code over
    to the new method. After that we add support for the rest of the
    upstream MSM SoCs (note these patches are piled high on top of
    Rohit's patches to add 8074 support to MSM[2] and my follow ups[3,4],
    but this should only matter to the MSM maintainers).

    This is one of the last items of code that still requires us to have
    a mach directory and a machine descriptor. We should be able to move
    the hotplug/smp code out of mach directories if this approach is
    accepted.

    Changes since v1:
    * Added pointers from cpu nodes to saw and acc nodes
    * Squashed nr_cpus removal into reorganization patch
    * Reworked bindings/documentation
    * Rebased onto v3.13-rc4
