This argument is useless for the vast majority of drivers. For now,
use __VA_ARGS__ wrapper macros so that that the *DRIVER_MODULE()
macros accept both the old version (with a devclass) and the new
version (which omits the argument and stores NULL in the
driver_module_data structure). This provides an API compatiblity
shim that can be merged to older stable branches.
Once all drivers relevant to 14.0 (both in and out of tree) have been
updated, the API compat shims can be dropped.

Add three hooks to the livedump process: before, after, and for each
block of dumped data. This allows, for example, quiescing the system
before the dump begins or protecting data of interest to ensure its
consistency in the final output.

This dumper can instantiate and write the dump's contents to a
file-backed vnode.
Unlike existing disk or network dumpers, the vnode dumper should not be
invoked during a system panic, and therefore is not added to the global
dumper_configs list. Instead, the vnode dumper is constructed ad-hoc
when a live dump is requested using the new ioctl on /dev/mem. This is
similar in spirit to a kgdb session against the live system via
/dev/mem.
As described briefly in the mem(4) man page, live dumps are not
guaranteed to result in a usuable output file, but offer some debugging
value where forcefully panicing a system to dump its memory is not
desirable/feasible.
A future change to savecore(8) will add an option to save a live dump.

Historically 32-bit Linuxulator under amd64 emulated the real i386
behavior. Since 3d8dd983 the old i386 Linux world can't be used under
amd64 Linuxulator as it don't know anything about amd64 machine (which
is returned now by newuname() syscall). So, add a knob to allow to swith
the behavior and use i386 Linux binaries on amd64.
Set knob to the new behavior as I think this is common to the modern

In order to support various types of data stored in device
tree properties or ACPI _DSD packages, create a new enum so
the caller can specify the expected type of a property they
want to read, according to the binding. The bus logic will use
that information to process the underlying data.
For example in DT all integer properties are stored in BE format.
In order to get constant results across different platforms we
need to convert its endianness to match the host.
Another example are ACPI_TYPE_INTEGER properties stored
as uint64_t. Before this patch the ACPI logic would refuse
to read them if the provided buffer was smaller than 8 bytes.
Now this can be handled by using DEVICE_PROP_UINT32 type.
Modify the existing consumers of this API to reflect the changes
and update the man pages accordingly.
