60116a7378 ARM: mach-shmobile: sh73a0 twd_base fix 
Fix the case of too late twd_base initialization for SMP
on sh73a0 which bas been broken because sh73a0 specific
smp_prepare_cpu() and percpu_timer_setup() changed order
in the commits:

05c74a6cbc
c413521eb4

Without this fix the sh73a0 SMP kernel panics on boot.

72f4d57923 ARM: mach-shmobile: sh73a0 SMP support 
Add SMP support for ag5evm and the sh73a0 processor.

Onlining and offlining works well, but at this point
offlined processor cores are not put into sleep mode.

There is no spinlock for syncing the secondary core
with the first one in this implementation. The code
instead relies on the cpu_online() check in __cpu_up().
