Subject: [PATCH v2 00/11] MIPS: Topology & DeviceTree CPU rework v2

This set mainly added DeviceTree based CPU probe support and reworked
topology handling for MIPS. In order to prepare for pure DeviceTree
boot for Loongson64. It can also convinient Yanjie's Inegnic jz4780/X2000
SMP/SMT support.

I've done build test for bmips, nlm, ip27 and boot test for malta with
34Kf, I6400 in QEMU, Loongson64 on a Loongson-3B1500 real machine.

Thanks.

v2:
  - Fixes
