From b24c2a925a9837cccf54d50aeac22ba0cbc15455 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 24 Nov 2009 02:48:18 -0800 Subject: 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.
