071aed40ac A foolish consistency; most parts of the kernel use bp->b_data, so 
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.

424619ca1a Fix the sparc64 console. 
Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them.  So, here we go:

	Add a new PROM console driver with a major number and everything.
	This is the default driver if nothing else attaches.  It does not
	use the keyboard driver since the PROM translates keystrokes itself.
	(Unfortunately it also swallows L1-A).

	Have the keyboard driver take over the console when it attaches on a
	serial port.  When a serial port detects a keyboard and attaches the
	keyboard driver, it needs to provide a set of consdev vectors.  They
	keyboard driver will use those to send I/O to the keyboard and mouse.

463931b3ba Nuke dk_establish() from orbit except from those ports which still use 
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

2d12c9e33b The bus_dma(9) implementation now allocates DVMA addresses in

allocated with bus_dmamem_alloc() _must_ be loaded by bus_dmamap_load_raw().

9f48bba3ae Add "install" target, so "make install" after building the kernel 
does something useful.  The target can be redefined by putting a
install-kernel-${MACHINE_NAME} target that fits your needs into
/etc/mk.conf.

6a33c86623 HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also, 
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.

f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file 
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
