acpi: Validate processor id when mapping the processor
When we want to identify whether the proc_id is unreasonable or not, we can call the "acpi_processor_validate_proc_id" function. It will search in the duplicate IDs. If we find the proc_id in the IDs, we return true to the call function. Conversely, the false represents available. When we establish all possible cpuid <-> nodeid mapping to handle the cpu hotplugs, we will use the proc_id from ACPI table. We do validation when we get the proc_id. If the result is true, we will stop the mapping. [ tglx: Mark the new function __init ] Signed-off-by:Dou Liyang <douly.fnst@cn.fujitsu.com> Acked-by:
