[PATCH 1/8] x86/boot: Detect 5-level paging support

5-level paging support is required from hardware when compiled with CONFIG_X86_5LEVEL=y. We will implement boot-time switch between 4- and 5-level paging later. Signed-off-by: Kirill A. Shutemov --- arch/x86/boot/cpucheck.c | 9 + arch/x86/boot/cpuflags.c
