can you get boot log with "memblock=debug"?

wonder if 

diff --git a/arch/x86/kernel/setup.c b/arch/x86/kernel/setup.c
index 4be9b39..c6724e4 100644 (file)
--- a/arch/x86/kernel/setup.c

@@ -912,6 +912,13 @@ void __init setup_arch(char **cmdline_p)
        memblock.current_limit = get_max_mapped();
        memblock_x86_fill();
 
+       /*

+       if (efi_enabled)
+               efi_reserve_boot_services(

wonder if double memblock ram array in memblock_x86_fill() that is overlapping with boot services.

Thanks
