[PATCH v3 3/5] x86: Kconfig: Remove CONFIG_NODES_SPAN_OTHER_NODES

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove CONFIG_NODES_SPAN_OTHER_NODES as it's enabled
by default. It is now enabled for x86(32 bit) configurations
and do not depend on X64_64_ACPI_NUMA config.
Because of that, on NUMA enabled system, early_pfn_in_nid() 
function is called by memmap_init_zone() during boot-time.
It doesn't affect the performance at run-time.
