void __cpuinit sn_cpu_init ( void  )

sn_cpu_init - initialize per-cpu data areas : cpuid of the caller

Called during cpu initialization on each cpu as it starts. Currently, initializes the per-cpu data area for SNIA. Also sets up a few fields in the nodepda. Also known as platform_cpu_init() by the ia64 machvec code.

void __init sn_setup ( char **  cmdline_p)

sn_setup - SN platform setup routine : kernel command line

Handles platform setup for SN machines. This includes determining the RTC frequency (via a SAL call), initializing secondary CPUs, and setting up per-node data areas. The console is also initialized here.
