Hi Morimoto-san,

I am having a little trouble with SMP on the kzm9g.  I am using Rafael's
renesas/next branch (5658c94), which includes all the patches above. The
only local change I have is to add KZM-A9-GT to mach-types. Perhaps I need
some other patches?


Using the default config I do get a prompt, but I see the following along
the way, multiple times.

intc: Registered controller 'sh73a0-intcs' with 77 IRQs
intc: Registered controller 'sh73a0-intca-irq-pins' with 32 IRQs
intc: Registered controller 'sh73a0-pint0' with 32 IRQs
intc: Registered controller 'sh73a0-pint1' with 8 IRQs
