ARM: 8390/1: irqflags: Get arch_irqs_disabled from asm-generic
Commit cb1293e2f594 ("ARM: 8375/1: disable some options on ARMv7-M")
causes the build to on ARMv7-M machines:
CC arch/arm/kernel/asm-offsets.s
In file included from include/linux/sem.h:5:0,
from include/linux/sched.h:35,
from arch/arm/kernel/asm-offsets.c:14:
include/linux/rcupdate.h: In function 'rcu_read_lock_sched_held':
include/linux/rcupdate.h:539:2: error: implicit declaration of function
'arch_irqs_disabled' [-Werror=implicit-function-declaration]
return preempt_count() != 0 || irqs_disabled();
asm-generic/irqflags.h provides an implementation of arch_irqs_disabled().
Lets grab an implementation from there!
