I agree with whoever thought it's odd that "read" is in lower case
when everything else is in upper case.
And honestly, I'd just siggest making the err_text simply have the
real user/kernel difference in it too, using something like
pr_alert("#PF error: 0x%04lx%s from %s mode\n", error_code, err_txt,
user_mode(regs) ? "user" : "kernel" );
The "oh, PF_USER and user_mode differs, so let's point that out
explicitly" thing is a good thing regardless.
