Kirill A. Shutemov 3677d4c6a2 x86/boot: Detect 5-level paging support ... In this initial implementation we force-require 5-level paging support from the hardware, when compiled with CONFIG_X86_5LEVEL=y. (The kernel will panic during boot on CPUs that don't support 5-level paging.) We will implement boot-time switch between 4- and 5-level paging later. Signed-off-by: Kirill A.
