fix typos in comments, mainly basicly -> basically.

Oops, forgot a debug printf

Now we use timestamp info, use direct console output instead of kernel
timestamped output for usage() reporting

Add ATAPI passtrough support giving the NetBSD/usermode kernel full control of
an ATAPI device. All ATAPI/SCSI commands are passed trough.

Note that ATAPI/SCSI calls are made in the foreground still

Add ATAPI passtrough support giving the NetBSD/usermode kernel full control of

Note that ATAPI/SCSI calls are made in the foreground still. Lengthy calls
will still hug the CPU until completion. Making it asynchronous is in the
pipeline

switch all ports to use uvm_init.c:uvm_md_init()

uvm_setpagesize() is now subsumed within this funciton.

Fix /dev/kmem access and make vmstat(1) `work'. Not sure all the results are
indeed valid or correct but at least it shows them without coredumping or
coredumping the kernel.

don't modify command-line parameters

allow specifing the root device with 'root=ldN' parameter

support multiple disk images (pass multiple disk=<path> parameters on the
command-line). while changing command-line params, rename tap= option to
net=

Split machdep.c into a MI part and a MD part.

Fix logic that checks if its the kernel or a userland process that causes the
trap. Signal sending still needs to be addressed.

Replace the SDL based genfb driver with a wsdisplay and wskbd driver that
implements the VNC (RFB) protocol.

To enable the VNC server, add 'vnc=640x480,5900' to the kernel command line
(where 640x48

Replace the SDL based genfb driver with a wsdisplay and wskbd driver that
implements the VNC (RFB) protocol.

To enable the VNC server, add 'vnc=640x480,5900' to the kernel command line
(where 640x480 is the desired fb resolution and 5900 is the TCP port).

Implement physio() for NetBSD/usermode the right way!

update usage message:

$ ./netbsd -h
-h: unknown flag
usage: ./netbsd [-acdqsvxz] [tap=<dev>,<eaddr>] [audio=<dev>] [<fsimg>]
(ex. "./netbsd tap=tap0,00:00:be:ef:ca:fe audio=audio0 root.fs")

add vaudio(4) audio device driver

first cut at networking support for usermode, doesn't fully work yet but
enough to get an address with dhcp and answer arps

Make signals work for NetBSD/usermode[i386] !

on second thought, set machine and machine_arch both from the host and
override module_machine

set machine_arch to that of the host

get rid of urkelvisor, and use same MD majors as the host

Add int $80 and sysenter opcodes to the x86 SIGILL opcode detector

Cleanup i386 register printing and opcode extraction

Remove the need for a siginfo structure in illegal instruction handling.

Print the signal we are supposed to deliver!

Fix error flag (carry) setting if its a pseudo error of EJUSTRETURN etc. Just
in case.
