Hi Magnus,

I tried out this patch on top of the next branch of Rafael's
renesas tree (5658c94) plus V2 of your Emma Mobile EV2 code but
I am only seeing one CPU.  Do I need some other tweaks?

The list of patches I have applied is as follows:

mach-shmobile: Emma Mobile EV2 SMP prototype code
ARM: mach-types: Manually add KZM-A9-GT
mach-shmobile: KZM9D board prototype support
mach-shmobile: Emma Mobile EV2 SoC base support
serial8250-em: Add DT support
serial8250-em: clk_get() IS_ERR() error handling fix
serial8250-em: Emma Mobile UART driver V2
serial8250: Introduce serial8250_register_8250_port()
serial8250: Clean up default map and dl code
serial8250: Use dl_read()/dl_write() on RM9K
serial8250: Use dl_read()/dl_write() on Alchemy
serial8250: Add dl_read()/dl_write() callbacks
8250.c: less than 2400 baud fix.
serial/8250_pci: Clear FIFOs for Intel ME Serial Over Lan device on BI
tegra, serial8250: add ->handle_break() uart_port op
clocksource: em_sti: Add DT support
clocksource: em_sti: Emma Mobile STI driver V2
clockevents: Make clockevents_config() a global symbol


And yes, I did enable CONFIG_SMP :)
