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

Hi Sudeep,
now that ACPI processor supports ARM64 did you check the
CPUIDLE_DRIVER_STATE_START trick in the code and its derivative ?
No, that is used only for C-State and ARM64 doesn't support it.
Patch 1/5 puts all the C-State code under #ifdef so that it's not
compiled on ARM64.
I deleted the patch 2/5 but there is a place where:
Sorry, I don't follow what you mean by that.
I meant I just deleted from my mailbox the patch 2/5, so I can't do
inline comment.
Ah ok, anyways LPI always starts from index 0. IIUC that was your main
concern.
