Now that ACPI processor idle driver supports LPI(Low Power Idle), lets enable ACPI_PROCESSOR_IDLE for ARM64 too. This patch just removes the IA64 and X86 dependency on ACPI_PROCESSOR_IDLE Cc: "Rafael J.

This causes a boot hang on QDF2432. cpuidle.off=1 works around the problem. I understand you're working on a fix to the problem in GICv3 code. If there's anything I can do to help, please let me know. Thanks, Christopher Covington -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
