GEOM ELI may double ask the password during boot. Once at loader time, and
once at init time.
This happens due a module loading bug. By default GEOM ELI caches the
password in the kernel, but without the MODULE_VERSION annotation, the
kernel loads over the kernel module, even if the GEOM ELI was compiled into
the kernel. In this case, the newly loaded module
purges/invalidates/overwrites the GEOM ELI's password cache, which causes
the double asking.
MFC Note: There's a pc98 component to the original submission that is
omitted here due to pc98 removal in head. This part will need to be revived
upon MFC.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
geom_bsd, geom_mbr and geom_sunlabel have been obsolete since Marcel
Moolenaar's geom_part was in FreeBSD 7. They haven't been in GENERIC
since FreeBSD 8. Add warning when used.
geom_vol_ffs has been obsolete since ufs support to geom_label was
committed in FreeBSD 5. It hasn't been in GENERIC since FreeBSD 5.
Add warning when used.
geom_fox has been obsolete since gmultipath was committed in FreeBSD 7.
(no warning added, since this is a very obscure class).
These will all be removed in FreeBSD 12.

No FreeBSD version bump, the userland application to query the features will
be committed last and can serve as an indication of the availablility if
needed.

in BSD and MBR classes, ie. if provider below us uses the same metadata,
don't create labels based on the metadata.
This allows to create labels on geoms with rank != 1 without hacks.

The only place where we want to not hold topology is when we read
(or write) the label to disk: in the case of a disk error with a
long recovery time, holding topology would prevent open/close of
any disk device.
This means that you can no longer trash your opened partitions by writing to
the sunlabel through another partition. This is similar to the semantics
implemented for BSD labels.

Do note though, that for now they are only valid after the first open

the relevant classes.
Some methods may implement various "magic spaces", this is reserved
or magic areas on the disk, set a side for various and sundry purposes.
A good example is the BSD disklabel and boot code on i386 which occupies
a total of four magic spaces: boot1, the disklabel, the padding behind
the disklabel and boot2. The reason we don't simply tell people to
write the appropriate stuff on the underlying device is that (some of)
the magic spaces might be real-time modifiable. It is for instance
possible to change a disklabel while partitions are open, provided
the open partitions do not get trampled in the process.
