[PATCH v3 0/2] cpufreq: Fix global boost state updates

[Christian Loehle]

Preserve the global boost state on failure and serialize concurrent
global boost writes.

Changes in v3:
- Explain the concurrent-writer race in patch 2 (Zhongqiu Han, Rafael).
- Add Reviewed-by tags from Zhongqiu Han and Sumit Gupta.
- No code changes.

Changes in v2:
- Split rollback and serialization into separate patches, with the
  corresponding Fixes tags (Zhongqiu Han)
- Carry Pengjie Zhang's Reviewed-by onto both patches since code
  is unchanged.
