(

void

)

collect_boot_cpu_data - Fill the boot_cpu_data structure.

This function collects and stores the generic processor information in the boot_cpu_data structure.

int __cpuinit init_per_cpu

(

int

cpunum

)

init_per_cpu - Handle individual processor initializations. : logical processor number.

This function handles initialization for every CPU in the system:

o Set "default" CPU width for trap handlers

o Enable FP coprocessor REVISIT: this could be done in the "code 22" trap handler. (frowands idea - that way we know which processes need FP registers saved on the interrupt stack.) NEWS FLASH: wide kernels need FP coprocessor enabled to handle formatted printing of lx for example (double divides I think)

o Enable CPU profiling hooks.
