[RFC Patch V1 30/30] x86, NUMA: Online node earlier when doing CPU hot-addition

2014-07-11 Thread Jiang Liu
With typical CPU hot-addition flow on x86, PCI host bridges embedded in physical processor are always associated with NOMA_NO_NODE, which may cause sub-optimal performance. 1) Handle CPU hot-addition notification acpi_processor_add() acpi_processor_get_info()
