I found out much to my surprise that our SMP box is not collecting ANY
entropy for /dev/random. All the interesting IRQs are over 16, and
nobody uses the console.
>From sys/i386/i386/mem.c 1.79:
/*
* XXX the data is 16-bit due to a historical botch, so we use
* magic 16's instead of ICU_LEN and can't support 24 interrupts
* under SMP.
*/
Why don't we just flip this from a 16 bit to a 32 bit parameter in time
for 4.0-RELEASE? Should just require a quick fiddle in mem.c and in
rndcontrol.
