Ignoring a NULL dev in device_set_ivars() sounds wrong, KASSERT it to
non-NULL instead.
Do the same for device_get_ivars() for reasons of symmetry, though
it probably would have yielded a panic anyway, this gives more precise
diagnostics.

were improperly relocated due to faulty logic in lookup_fdesc()
in elf_machdep.c. The symbol index (symidx) was bogusly used for
load modules other than the one the relocation applied to. This
resulted in bogus bindings and consequently runtime failures.
The fix is to use the symbol index only for the module being
relocated and to use the symbol name for look-ups in the
modules in the dependent list. As such, we need a function to
return the symbol name given the linker file and symbol index.

processes forked with RFTHREAD.
- Use a goto to a label for common code when exiting from fork1() in case
of an error.
- Move the RFTHREAD linkage setup code later in fork since the ppeers_lock
cannot be locked while holding a proc lock. Handle the race of a task
leader exiting and killing its peers while a peer is forking a new child.
In that case, go ahead and let the peer process proceed normally as the
parent is about to kill it. However, the task leader may have already
gone to sleep to wait for the peers to die, so the new child process may
not receive a SIGKILL from the task leader. Rather than try to destruct
the new child process, just go ahead and send it a SIGKILL directly and
add it to the p_peers list. This ensures that the task leader will wait
until both the peer process doing the fork() and the new child process
have received their KILL signals and exited.

- Rename the enum for memsize from ISA_IVAR_MSIZE to ISA_IVAR_MEMSIZE
since using 'MSIZE' in the macro invocation of ISA_ACCESSOR() conflicts
with the 'MSIZE' kernel option. The accessor function is still
isa_get_msize().
or fifo in UFS2, the normal ufs_strategy routine needs to be used
rather than the spec_strategy or fifo_strategy routine. Thus the
ffsext_strategy routine is interposed in the ffs_vnops vectors for
special devices and fifo's to pick off this special case. Otherwise
it simply falls through to the usual spec_strategy or fifo_strategy
routine.

It must be removed because it is done without the pipe being locked
via pipelock() and therefore is vulnerable to races with pipespace()
erroneously triggering it by temporarily zero'ing out the structure
backing the pipe.
It looks as if this assertion is not needed because all manipulation
of the data changed by pipespace() _is_ protected by pipelock().
