Lookup isn't done every time the system goes idle now, but it can still
take > 1800 instructions in the worst case, so if cpu interrupts are kept
disabled then it might lose 20 characters of sio input at 115200 bps.
Fixed style in vm_page_zero_idle().

only inlined and thus not available in DDB.
I'm sure Bruce will have 23 additions to these 30 lines of code, but
at least it's a starting point. ;-)
change typematic rate, or the X server (XFree86 or Accelerated X)

So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem. (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).
In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.
It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.
The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.
(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)
This should go into RELENG_2_2.

This header was missed in previous cleanups because it didn't include
<sys/ioctl.h> or <sys/ioccom.h>. Clean it now:
- #include <sys/types.h> since it is necessary to make the header self-
sufficient (there are a couple of u_char's).
- uniformized idempotency ifdef. Copied the style in the 4.4Lite
ioctl headers.
and fixed everything that depended on getting it from the wrong
place. Most of the broken things actually only depended on getting
the declaration of their interrupt handler from "ioconf.h".
