.SH NAME
init_per_cpu \- Handle individual processor initializations.
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int __init init_per_cpu  (int \fIcpunum\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIcpunum\fB\fR
logical processor number.
.SH "DESCRIPTION"
.PP
This function handles initialization for *every* CPU
.SH "IN THE SYSTEM"
.PP
.PP
o Set ``default'' CPU width for trap handlers
.PP
o Enable FP coprocessor
.SH "REVISIT"
.PP
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.)
.SH "NEWS FLASH"
.PP
wide kernels need FP coprocessor enabled to handle
formatted printing of lx for example (double divides I think)
.PP
o Enable CPU profiling hooks.
