Subject: x86: process_32.c declare cpu_number before they get used
X-Git-Tag: firefly_0821_release~17842^2~2^2~26
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=fb26132b441e75d6ba9996efc29b42081aee0abd;p=firefly-linux-kernel-4.4.55.git

x86: process_32.c declare cpu_number before they get used

Moved DECLARE_PER_CPU(int, cpu_number) from CONFIG_X86_32_SMP to CONFIG_X86_32
because cpu_number is required for both.
And include asm/smp.h in process_32.c
