Kernel SMP support with only cpu safe?

[Richard MAHONEY]

List members,

I am running an HP Proliant ML150 with only one cpu [CPU: Intel(R)
Xeon(TM) CPU 3.00GHz (2992.51-MHz K8-class CPU)]. The details are below.
The slot for the second cpu is empty and SMP support has not been
enabled in the kernel. The upshot of seems to be that `top' doesn't
indicate the cpu state, i.e.:

last pid: 50248;  load averages:  0.00,  0.00,  0.00 up 1+01:52:17  12:19:34
52 processes:  1 running, 50 sleeping, 1 zombie
CPU states:     % user,     % nice,     % system,     % interrupt,     %idle
Mem: 153M Active, 387M Inact, 115M Wired, 28M Cache, 111M Buf, 191M Free
Swap: 2020M Total, 2020M Free

The question ... Would recompiling the kernel with SMP support resolve
this issue? And, considering that I only have one cpu, would this be
safe? I'd be grateful for any advice.
