[PATCH V2 0/5] cpufreq: loongson3: Fix wrong behaviors on multi-node servers

[Huacai Chen]

Our server productions (e.g. Loongson-3D6000/3E6000) can have multiple
nodes in one package and SMC mailboxes are also per-node. However, the
current driver has wrong behaviors on multi-node servers, including: id
field in smc_message is too narrow, mutex is not per-node, IOCSR read/
write can only perform on the current node, etc. This series fix all the
above problems.

V1 -> V2:
1. Fix typos and add Fixes tags.
2. Fix loongson3_cpufreq_get() return values.
3. Use nid_to_addrbase() rather than hard code.
4. Guard some code with CONFIG_SMP to avoid build errors.

Hongliang Wang & Huacai Chen (5):
  cpufreq: loongson3: Make this drvier depend on MACH_LOONGSON64
  cpufreq: loongson3: Adjust the width of id and val in smc_message
  cpufreq: loongson3: Replace per-package mutex with per-node
  cpufreq: loongson3: Use global physical CPU ID in get/target callbacks
  cpufreq: loongson3: Replace IOCSR read/write with MMIO ones
