I'd like to note that below set of patches:
1c9df907da83 random: fix circular include dependency on arm64 after addition of percpu.h
83bdc7275e62 random32: remove net_rand_state from the latent entropy gcc plugin
f227e3ec3b5c random32: update the net random state on interrupt and activity
also break ARM build for the case:
#if defined(CONFIG_SMP) && !defined(CONFIG_CPU_V6)
config: keystone_defconfig
CC arch/arm/kernel/signal.o
In file included from ../include/linux/random.h:14,
