being removed from GENERIC in 12. Always print PNP info for ISA when
it exists: it doesn't depend on ISAPNP. Add PNP ID to orm and vga to
prevent us from warning about them since those devices aren't being
removed from GENERIC. PNP devices will be removed from GENERIC too,
but they will be automatically loaded, so need no warning. We don't
warn for non-GENERIC kernels because people running them are presumed
to know what they are doing.

The daemonfd function is equivalent to the daemon(3) function expect that
arguments are descriptors. For example dhclient(8) which is sandboxed is
unable to open /dev/null to close stdio instead it's allows to fail
daemon(3) function to close the descriptors and then do it explicit in code.
Instead of such hacks we can use now daemonfd.
This API can be also helpful to migrate system to platforms like CheriBSD.

clang does not know that two lookup calls will return the same
pointer, so it assumes correctly that using the old pointer
after dropping the reference to it is a bit risky.
Sometimes caller is only interested in how many clones
are there and NULL pointer is passed for the destination
buffer. Do not pass it to copyout then.
if_clone_attach function will drop the reference on failure which will
free the if_clone structure. No need to do it second time.

This should help reduce confusion between syscon/syscons a little bit.
syscon is a resource generally modeled by FDT platforms, and not to be
confused with syscons.
Allow more flexibility by kobj'ifying syscon and splitting out fdt specific
bits in preparation of a move to the extres framework.
The generic fdt driver has been moved to syscon_generic.c and the fdt
requirement has been removed from the syscon interface, as is common to the
extres framework.

ISA PNP card support (replace by hand version in if_ed). Move module
declarations to the end of some files. Fix PCCARD_PNP_INFO to use
nitems(). Remove some stale comments about pc98, turns out the comment
was simply wrong.
about CIS3/CIS4, including studies I've done on my large collection of
PC Cards bought off e-bay over the years since the original entry as
well as conversations I've had at conferences.
The only users of the functions were db_read_bytes() and
db_write_bytes() ddb(4) interfaces. Replace the calls with direct
reads and writes, which are automatically atomic on 64bits and n32.
Note that removed assembler implementation for mips32 is not atomic
anyway.

leaves the firmware event queue (fwq) as the only queue that can take
interrupts for others.
This simplifies cfg_itype_and_nqueues and queue allocation in the driver
at the cost of a little (never?) used configuration. It also allows
service_iq to be split into two specialized variants in the future.
