x86: silence section mismatch warning - get_local_pda
Take out part of get_local_pda referencing __init function (free_bootmem) to new (static) function marked as __ref. It's safe to do because free_bootmem is called before __init sections are dropped. WARNING: vmlinux.o(.cpuinit.text+0x3cd7): Section mismatch in reference from the function get_local_pda() to the function .init.text:free_bootmem() The function __cpuinit get_local_pda() references a function __init free_bootmem(). If free_bootmem is only used by get_local_pda then annotate free_bootmem with a matching annotation.
