* Don't initialise the timer until *after* we install the timecounter to
avoid a race between timecounter initialisation and hardclock.
* Tidy up bootinfo somewhat including adding sanity checks for when the
kernel is loaded without a recognisable bootinfo.

Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
o Reintroduce func_intr and func_arg and use the to store the
interrupt handler to call.
o Create a pcic_pci_func_intr to call the real interrupt handler
iff the card hasn't been ejected.
o Remove some checks in pcic_setup_intr now that it is used
exclusively for isa routed interrupts.
o Defer the eject event until later too, but make sure we can't
do any client driver ISR calling in the interrum.
o Add some simple code to make sure that we don't attach more
than one child. This should fix pccardd starting twice
problem (ala single user -> multi-user when you started pccardd
by hand in SU).
MFC: after jkh thinks I've put the crack pipe away.
- Use some simple #define's at the top of the files for proc -> thread
changes instead of having lots of needless #ifdef's in the code.
- Don't try to use struct thread in !FreeBSD code.
- Don't use a few struct lwp's in some of the NetBSD code since it isn't
in their HEAD.
The new diff relative to before KSE is now signficantly smaller and easier
to maintain.
automatically change the code to add
struct proc *p = td->td_proc;
because now 'td' is probably capable of being NULL too.
I expect to see more of this kind of error during the 'weeding'
process. It's too easy to make. (junior hacker project.. look for these :-)

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

- We don't need to test the console right before we vfprintf() the panicstr
message. The printing of the panic message is a fine console test by
itself and doesn't make useful messages scroll off the screen or tick
developers off in quite the same.

* Switch to proc0's stack and backing store before calling ia64_init
so that we don't rely on the loader's stack at all.
* Change kernel entry point name from locorestart to __start.
'struct tty' was out of sync in user and kernel due to dev_t/udev_t
mixups. This takes advantage of the fact that dev_t changes type in
userland, so it isn't too pretty.
overflow if uap->nsops (which is already unsigned) is over INT_MAX;
consequently, the bounds check below becomes valid. Previously, if a
value over INT_MAX was passed in uap->nsops, the bounds check wouldn't
catch it, and the value would be used to compute copyin()'s third
argument.

and linux_sendsig functions guarded their debugging output with
ldebug(sigreturn). This has been mistaken for a cut-n-paste bug,
and was replaced by ldebug(rt_sendsig) and ldebug(sendsig) resp.
Since the sendsig functions are not syscalls, this brokei any
build that defines DEBUG.
The fix maps both functions to the unused syscall 0 so that they
can be enabled/disabled independently from sigreturn, but not
independently from each other.
it to the MI area. KSE touched cpu_wait() which had the same change
replicated five ways for each platform. Now it can just do it once.
The only MD parts seemed to be dealing with fpu state cleanup and things
like vm86 cleanup on x86. The rest was identical.
XXX: ia64 and powerpc did not have cpu_throw(), so I've put a functional
stub in place.
