Building the kernel with -Werror-implicit fails pretty fast with this..
arch/i386/kernel/process.c: In function '__switch_to':
arch/i386/kernel/process.c:645: error: implicit declaration of function 'load_user_cs_desc'
arch/i386/kernel/process.c: In function 'arch_add_exec_range':
arch/i386/kernel/process.c:915: error: implicit declaration of function 'set_user_cs'
