Although there was nothing wrong with getwc() and putwc(), getwchar()
and putwchar() assumed that <stdio.h> had been included before <wchar.h>,
which is not allowed by the standard.
sparc v9 ABI. The Elf_Rela records for local symbols appear to already
have the symbol's value added in to the addend field, even though the ABI
specifies we need to lookup the symbol and add its value too. This breaks
text relocations in klds because the symbol's value is added twice, and
the resulting address points off into nowhere land, so for now just use
the addend.

The advanced stage of computer assisted hardware design and
verification is aptly illustrated by the fact that this is necessary
because only the first ports in a single-chip, dual-port async

Rework the detection of raw-disk offsets in disklabels. This actually
unearthed a number of bugs in the (now) previous version.
Also accept labels which don't have a magic RAW_PART, provided they don't
confuse us too much.
Change the order of our sanity-checks on labels found on disks to be more
robust.
Check against MAXPARTITIONS in our sanity-check and reject disklabels
we cannot cope with.
Create new g_bsd_modify() function to implment disklabel modifying
ioctls.
Implement DIOCSDINFO and DIOCWDINFO with the provision that the latter
still not writes your change back to disk. I didn't have the nerves

In the start routine, use g_call_me() for complex ioctls to prevent
sleeping.

This will eventually replace g_slice_addslice() which gets changed from
grabbing topology to requing it in this commit as well.

This prevents people from sleeping in the UP/DOWN I/O path by mistake

stalls all I/O processing in the given direction.

to be performed in the event-thread.
To do this, we need to lock the eventlist with g_eventlock (nee g_doorlock),
since g_call_me() being called from the UP/DOWN paths will not be able to
aquire g_topology_lock.
This also means that for now these events are not referenced on any
particular consumer/provider/geom.
For UP/DOWN path use, this will not become a problem since the access()
function will make sure we drain any bio's before we dismantle.

SPECFS will DROP_GIANT() ... PICKUP_GIANT() around calls to the

Notice that the interrupt path is not affected by this!
This does _NOT_ work for drivers accessed through cdevsw->d_strategy()
ie drivers for disk(-like), some tapes, maybe others.
