x86: Move find_smp_config() earlier and avoid bootmem usage
Move the find_smp_config() call to before bootmem is initialized. Use reserve_early() instead of reserve_bootmem() in it. This simplifies the code, we only need to call find_smp_config() once and can remove the now unneeded reserve parameter from x86_init_mpparse::find_smp_config. We thus also reduce x86's dependency on bootmem allocations. Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4B0BB9F2.70907@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
