From: "Hector.Yuan" <redacted> When hotpluging policy cpu, cpu policy init will be called multiple times. Unplug CPU7 -> CPU6 -> CPU5 -> CPU4, then plug CPU4 again. In this case, devm_remap will double remap and resource allocate fail. So replace devm_remap to ioremap and release resources in cpu policy exit.
