x86/entry/32: Add debug code to check entry/exit cr3 Add a config option that enabled code to check that we enter and leave the kernel with the correct cr3. This is needed because we have no NX protection of user-addresses in the kernel-cr3 on x86-32 and wouldn't notice that type of bug otherwise. Signed-off-by: Joerg Roedel <jroedel@suse.de>
