ugly to add -I.../usr.bin to do this. instead, add appropriate
comments in the source to where the files are actually coming from.
- use NETBSDSRCDIR as appropriate
- some minor makefile delint
pointer, in case the caller grew its stack dynamically.
Also beef up the checks to catch cases where the call stack passes
through the exception handling code in locore. In this case, the
frame pointer and program counter are in the trapframe/intrframe.
This eliminates problems where the underlying interrupt handler isn't the
specific layer calling scsipi_complete() for a given scsi transaction.
This avoids deadlocks where the kthread that called the autoconf routines
to configure a scsibus shouldn't be the one put to sleep waiting on a
scsipi_complete (only the scsibus's kthread should be doing that).
To avoid jitter this will force the scsibus's to probe in the order they
run through autoconf (so machines with multiple bus's don't move sd* devices
around on every reboot).
Also, remove a call to path_create() that causes the `prepend' path held by
pkg_perform() to be deleted, causing a core dump later when pkg_perform()
tries to remove it itself.
Also, change the way console input is passed to the subprocess -- instead of
echoing it in sushi, instead set the pty to cooked mode and have it do any
echoing. This will work better if we have scripts that accept input (sometimes
we don't want it visible; e.g. if it's a password) and also has the side effect
of allowing a command to be interrupted with ^C.
