Add 8 and 16 bit [f]cmpset for armv4/5 (kernel only).

I'm sorry about the long delay on this. I was originally just going to wait a few days until the changes got MFC'd to 12, then forgot all about it.

Yep, this is much cleaner than the old code.

I think I just confused myself about the need for the pwm(9) entry while I was in the middle of doing a bunch of MFC stuff. Thanks for fixing it.

I never put either of those things in a commit message if there's a phab to cite, because it has all the details. But I think I'm in a minority about that. Anyway, no need to mention me in the commit at all. :)

Get rid of _procname entirely. Just use procname in the whole run_rc_command.

IMO, the much easier fix is to change the call to bus_generic_attach() at the end of the ichsmb_attach() routine to:

I wonder if a good option for this would be to install a symlink rather than hardlink, and don't replace an existing link. That way by default people get an objdump that's mostly compatible with the old one, and if they need full compatibility they can install the pkg and change the symlink to point to it.

Upon further reflection, I think the changes to iic(4) in this diff are correct and should be committed. The problem of iicbus_request_bus() returning an ambiguous mix of IIC_Exxxxx or errno values because of iicbus_poll() doing so is a separate problem and should be fixed separately.

Unfortunately, the comment that says "all iicbus functions return IIC_Exxxxx status values" is incorrect. There is one exception which screws up this whole error-translation thing: iicbus_poll() can return an errno and the rather important errno values it might return, EINTR and ERESTART, have no corresponding IIC_Exxxxx value they could be translated to so that they can later be translated back.

Add some details to the manpage about the barrier and cache operations performed by arm_drain_writebuf().

So far there was more commenting on mailing lists than here. Summarizing the feedback from both venues so far...

Use install to create the acct file with correct ownership and permissions instead of umask+touch.

I love the clean simplicity of this after all the back and forth on mailing lists about markup languages and other complications that were far beyond this original simple vision.
