ip_output(). This flag, if set, causes ip_output() to set
DF in the IP header if the MTU in the route is not locked.
This allows a bunch of redundant code, which I was never
really all that happy about adding in the first place, to
be eliminated.
Inspired by a similar change made by provos@openbsd.org when
he integrated NetBSD's Path MTU Discovery code into OpenBSD.
16 bit sun checksum. This flag is needed when making iso 9660 images which
are bootable on both sparc and pmax machines.

Also fix egregious bug where we would never decrement
the islocked recursion counter. I guess this means
that we don't recurse on this platform! All of this should
go away when we have real lock primitives to use in drivers.
machines are one is very likely to run into SES units (what with all
the D1000's && A1000s out there now). I'll do it in sparc64 as soon
as I get that running for myself.
Because of this kvtophys() of wired pages did set the leftmost bit, causing
the pager to hang while swapping. This is now fixed by using another
free bit in the PTE as wired bit instead.
This fixes PR#11121.
Many thanks to Chuck Silvers that found what the problem was!
the UPC driver needs to know whether the system's got an IOEB in it.
The way this is implemented is a mess -- I need to get my mind round
autoconfiguration again.
when deallocating a fragment that has not made it to disk yet.
Also, during dirops, give the directory vnode an extra reference in
SET_DIROP, to ensure its continued existence during SET_ENDOP, preventing
a possible NULL-dereference there.
These two changes should close PR #11064.
serial console even if the PROM uses bitmap console.
- Remove zs_hwflags since news68k does not have keyboard nor mouse at zs;
check zschan address set in zscninit() to detect console device.
- Use BPS_TO_TCONST() to set baudrate in zs_init_reg[].
- Remove zs_get_chan_addr(), which is not needed anymore.
when sharing an interrupt with other devices:
check sc->sc_enabled, and drop the interrupt if its' off.
Also check for IFF_RUNNING, on advice of Enami Tsugotomo.
