Subject: [PATCH v2 0/4] cpufreq: Fix some boost errors related to CPU online and offline.

This patch series fix some boost errors related to CPU online and offline:

 - patch 1 fix an error that causes the CPU stay on base frequency after a
   specific operation

 - patch 2 introduce a more generic way to set default per-policy boost
   flag and fix a error that causes the per-policy boost flag remians true
   when cpufreq_driver boost disabled

 - patch 3 fix an error in cppc_cpufreq that causes the CPU stay on base
   frequency when boost flag is true

 - patch 4 remove the set_boost in acpi_cpufreq_cpu_init(), since it will
   be executed in cpufreq_online

Change since v1:
 - remove update of min_freq_req
 - optimize the conditions for executing set_boost in cpufreq_online
 - fix another error in cppc_cpufreq
 - remove set_boost in acpi_cpufreq_cpu_init()

Lifeng Zheng (4):
  cpufreq: Fix re-boost issue after hotplugging a cpu
  cpufreq: Introduce a more generic way to set default per-policy boost
    flag
  cpufreq: CPPC: Fix wrong max_freq in policy initialization
  cpufreq: ACPI: Remove set_boost in acpi_cpufreq_cpu_init()
