- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.

the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));
by someone!
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.
-sys/lib/libkern builds as library per default (as it was documented all
the time)
-ports able to LKM set "KERN_AS=obj" explicitely in their Makefiles
(for now; should depend on actual "option LKM" or -better- functions
included for LKM use should be pulled in by a stub)
-always link libcompat before libkern - libkern stuff can be referred to
by libcompat, but not the other way
which require special handling, e.g. sigreturn on m68k.
This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.
u-area in machine-dependent code. Instead, call exit2() to schedule
the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).
interrupts; if there's an interrupt pending (i.e. because the user pressed
a key or moved his mice while the kernel was being loaded), the interrupt
handler may safely be run. Fixes PR port-hp300/5397.
reading the DIO device ID at select code 7, but rather hard-wire the ID
to the IHPIB ID. This prevents us reading what might look like a valid
ID to another device when IHPIB is present. (IHPIB doesn't always return
a correct device ID, grumble.)
