Hm, I'm getting build failures on x86:

kernel/sched/cputime.c:60:2: error: implicit declaration of 
function ‘irq_time_write_begin’ 
[-Werror=implicit-function-declaration]
kernel/sched/cputime.c:72:2: error: implicit declaration of 
function ‘irq_time_write_end’ 
[-Werror=implicit-function-declaration]
kernel/sched/cputime.c:274:2: error: implicit declaration of 
function ‘static_key_false’ 
[-Werror=implicit-function-declaration]

Config attached.

Thanks,

	Ingo
