Hi!
Just want to let your know I can send some patches to be committed
to -current. Anyone interested? I'am asking because I tried
to communicate with some FreeBSD people this week, but their
did't respond for unknown reason (busy?).

1) syscall returns 32-bit value:
r2 = rv[0];

r3 is irrelevant here (ABI: "32-bit values returne
Some working notes.
I've written the libc/csu part, kernel successfully starts init and init
forks off for the execve of -sh,
(http://tzukanov.narod.ru/freebsd390/bootlog.txt)
but there is problem with printing from userland, e.g. output from
userland are not visible. Write syscall to descs 1,2
Reaches mount root prompt in emulator.
More info is on http://tzukanov.narod.ru/freebsd390/
