[parisc-linux] user_mode() right?

[Grant Grundler]

Hi all,
top currently reports the following on my a500:
CPU states:   0.3% user,  99.7% system,   0.0% nice,   0.0% idle

while the system is idle. ie idle time is being accounted
to the system time.

While trying to understand this, I ran across the following comment:

/* XXX should we use iaoq[1] or iaoq[0] ? */
#define user_mode(regs)                 (((regs)->iaoq[0] &  3) ? 1 : 0)

Is iaoq[0] correct?

thanks
