with either of these two arguments. Not sure how this got broken given
that in the original patches it was fine -- presumably a merging
mistake.

Seems to work great in the type II cf<->pccard adapter that came with
the card. Others have reported with different chipsets for the pccard
bridge that additional support is needed to make this card work with
the 3.3 volts it needs.
instead, use the bus_print_child_* functions to display the error message.
Also, since this is more of a warning than an error, hide it behind
bootverbose.
Similarly, if isa_assign_resources() fails to allocate resources to a
device, use bus_print_child_header() instead of device_printf(), and
display the resources that could not be allocated if bootverbose is true.

I made the style more consistent in ip.c - this should really have

the gating of system calls that cause modifications to the underlying
filesystem. The gating can be enabled by any filesystem that needs
to consistently suspend operations by adding the vop_stdgetwritemount
to their set of vnops. Once gating is enabled, the function
vfs_write_suspend stops all new write operations to a filesystem,
allows any filesystem modifying system calls already in progress
to complete, then sync's the filesystem to disk and returns. The
function vfs_write_resume allows the suspended write operations to
begin again. Gating is not added by default for all filesystems as
for SMP systems it adds two extra locks to such critical kernel
paths as the write system call. Thus, gating should only be added
as needed.

add that to the comments.

Perhaps the best way to deal with this is a static buffer or a static

Old curses used to change the behavior of the tty and how carriage

basis within the library rather than using the tty modes. Since
talk is bypassing ncurses, it was missing the conversion.
