is called.
- Change sysctl_out_proc() to require that the process is locked when it
is called and to drop the lock before it returns. If this proves too
complex we can change sysctl_out_proc() to simply acquire the lock at
the very end and have the calling code drop the lock right after it
returns.
- Lock the process we are going to export before the p_cansee() in the
loop in sysctl_kern_proc() and hold the lock until we call
sysctl_out_proc().
- Don't call p_cansee() on the process about to be exported twice in
the aforementioned loop.
p_pgrp since the pgrp locking went in. We also don't need it to check for
invalid values in the options argument to wait1(), so push Giant down
slightly.
with a back off. This was discovered when Luigi sent me code to
handle this for Etherboot. The Etherboot patch worked okay but
FreeBSD's tftpd had trouble handling it and would fail to transfer
the file since it would abort on send and not retry.

drivers with MI portions into the MI notes. Device drivers such as busses
like the isa, eisa, and pci devices are now in the MD NOTES section even
though they have some MI code. This will ensure that only the proper bits
of device drivers will be included due to the optional bits dependent on
the busses in sys/conf/files. This commit also takes the stance that since
hints are ignored in NOTES anyways, it is ok to include hints for a bus
that may not be present.

Change case of POLLNVAL as an error.
Remove POLLHUP and POLLERR from one case, their place is most likely
amongst read events.

While it may have allowed the XFree86 4 port to build; it killed TONS
of other ports. The XFree86 4 can be patched to not use its macro a lot
easier than figuring how to deal with 1000 other now-broken ports.
since we have no ACPI feature in the installation kernel at this time.
Without having this, we'll see
ACPI no autoload failed -- no such file or directory
message at boot time, and it makes some confusion to the users. We can
backout this change if installation kernel has ACPI feature.

and add some compatibility defines. Add fields for ins and locals to
struct reg also for the same reason; these aren't filled in yet because
getting at those registers sucks and I'd rather not save them in the
trapframe just for this. Reorder struct reg to be ABI compatible as
well. Add needed include of machine/emul.h.
This gets pmdb (poor man's debugger) from OpenBSD mostly compiling but it

newer ultras and probably other sun machines. This is a pretty decent
chip with 32 byte read and write fifos and support for many higher baud
rates. It supports hdlc and sdlc as well as asynchronoue serial, but the
goal here is just decent serial console support for the sparc64 port, so
these modes are not expected to be supported. So far this only has support
for the low level routines used by kernel printf and thus ddb over serial,
a character device which can be used for login consoles has not yet been
written.
