Correct typo in a comment. ok'ed by wiz@.
New home for rmd160.h.
Use crypto/rmd160.h.
Don't try to bus_dmamem_alloc everytime we want to load the firmware as
it can fail all too easily. Instead bus_dmamap_load the cached copy and
create the command blocks for the device to load it accordingly.

Thanks to scw and mrg for reviewing this.

Closes PR 29892 (I hope).
Whitespace and change a comment slightly.
Sanity check negative values in the maximum size and number of nodes
arguments to avoid a crash while mounting a tmpfs file system.  Add a
regression test for this too.  Noticed by chs@.
Only consider valid flags in the root mode's parameter given by the user.
I doubt the unchecked value could bring us problems, but better to be safe
than sorry.
Add entry about showmount IPv6 support.
Kill reference to tmpfs(9).  Noticed by "pancake".
tcp_callrpc(): bring in the FreeBSD version of this call. It uses the
"new" rpc functions and works with IPv6.
Fix some type mismatch issues (gid_t and uid_t are unsigned); pointed out
by chs@.
ANSIfy. de-P(). Syle nits.
Fixing showmount was easier than I thought..
Implement the getargs option.  I knew the code in the kernel had to be of
some use...
Re-work the handling of incoming I/O in RAIDframe:
- introduce rf_buf_queue_check() which checks to see if there
is work to do in the incoming buffer queue
- rf_RaidIOThread() is now responsible for calling raidstart(), and is
also now the only place that calls raidstart()
- raidstrategy() now just queues requests in buf_queue
and signals rf_RaidIOThread() that work has arrived

Hopefully addresses PR#30233
