8c027ecbba Eliminate a compiler warning with gcc3.3 on AMD64, where speed is
a 32 bit int which can never be > ULONG_MAX / 8.  Its an 'always true'
warning.

51da11a27a Fix some easy, global, lint warnings. In most cases, this means
making some local variables static. In a couple of cases, this means
removing an unused variable.

084254f807 - Add minimal support for TI16754 4xUART chip into sio(4) driver and remove
now unnecessary hack from the previous commit;
- Add support for Interrupt Latch Register (ILR) into puc(4). So far only
  ILRs compatible with specifications from Digi International are supported.
  Support for other types of ILRs could be easily added later;
- Correct clock frequency for IC Book Labs Dreadnought x16 Lite board;
- Enable ILR detection/usage for IC Book Labs Dreadnought x16 boards.

a2a101e766 Add initial support for IC Book Labs Dreadnought x16 Pro 16-ports card. Since
this card is based on 16750 UART, modify sio(4) a bit to ignore 16750-specific
7th bit of MCR when probing card. This allows card to be detected and attached
as 16550A-compatible device. More work needs to be done in order to enable
nice 16750-specific features such as larger fifo buffer and higher speeds.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

263444cfbf Change the console interface to pass a "struct consdev *" instead of a

for retrieving their softc.

d36644f2d9 Be nice. There are evidentally a number of different cards that
identify themselves as serial cards that it would be desirable to
attach a different driver than sio to.  Since we are claiming all
serial cards, this is not possible.  Instead, return -100 to indicate
that we're willing to take the card, but still allow other drivers to
attach.

97c6f4f976 Add yet a quick flag to sio: 0x100000 "Scratch pad register missing".
The advanced stage of computer assisted hardware design and
verification is aptly illustrated by the fact that this is necessary
because only the first ports in a single-chip, dual-port async
PC-Card product lacks this register.

This facilitates the use in circumstances where you are using a serial
console as well. GDB doesn't support anything higher than 9600 baud (19k2
if you are lucky), but the console does.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

8fdb202d85 Support more than 32 sio unit numbers. The maximum unit number is now
(65536 * 32 - 1), but MAKEDEV only supports up to (32 * 32 -1).  Device
names use the unit number in base 32 for all "digits".

This required fixing an old bug in MAKEDEV:ttyminor().  Its arg was the
global $unit instead of $1.

e968c4ef3c Hacks for measuring interrupt latency. Interrupt latency can be
measured accurately for periodic interrupts provided the interrupts
don't need to be serviced very quickly to keep their period almost
constant.  sio output interrupts have this property (interrupt service
can be delayed for up to 1 character time without the period changing).

This is non-optional and undocumented so that it can be added and
removed easily.  It has no significant effect unless it is enabled by
hacking on a variable using a debugger.  Hardclock and statclock interrupts
would work even better for this, at least on i386's, provided their
interrupt handlers are fast (as they are in -current but not in -stable
or in my version of -current).
