BTW: my mom always said "Don't use floating-point code in kernel." ;-}
Compile drivers/scsi/scsi_debug.c after defining "SCSI_DATARATE" and "SCSI_SETUP_LATENCY".
This generates floating-point code in kernel, on intel something like:
fldl .LC25 fmulp %st,%st(1) fldl .LC26 fdivr %st,%st(1)
What's happen now ? request_module(...) in kernel's SIGILL handler ? Failed ? Press the magic red button, and generally don't boot with init=/usr/bin/porvray again. :-}
I think there are far many more reasons not to modularize FP-emulation.
