gpart(8) has functionality to change the label of an GPT partition.
This functionality works like it should, however, after a label change
the /dev/gpt/ entries remain unchanged. glabel(8) status output remains
unchanged. The change only takes effect after a reboot.

hardware but lack the larger fifos rev 5 hardware should have.
The linux world (where our FDT data comes from) solved this by adding
a new property to pl011 nodes, "arm,primecell-periphid". When this
property is present, its values override the values in the hardware
periphid registers. For pl011 rev 5 hardware with small fifos, they
override the id so that it appears to be rev 4 hardware.
The driver now uses the new property when present. It also continues
to check the device compat string, to handle older fdt data that may
still be in use on existing systems (on RPi systems it is common to
update system software without updating fdt data which is part of the
boot firmware).

Some SIMs report much less untagged device openings then tagged ones.
Target mode devices are not handled by regular probing routines, and so
there is nothing to increase queue size for them to the SIM's maximum.
To fix that resize the queue explicitly on ctl periph registration.
This radically improves performance of mpt(4) in target mode.
Also fetch and report device queue statistics in `ctladm dumpstructs`,
since regular way of `camcontrol tags` is not usable in target mode.

Queue statistics has nothing to do with presence or absence of INQUIRY

Those places were not taking into account uk_ppera.
At present one allocation is always used by one slab, so uk_ppera must

- XPT_NOTIFY_ACKNOWLEDGE was not handled, causing stuck requests.
- XPT_ABORT was not even trying to abort active ATIOs/INOTs.
- Initiator's tag was not stored and not used where needed.
- List of TM request types needed update.
- mpt_scsi_tgt_status() missed some useful debugging.
After this change global TM requests, such as reset, should work properly.
ABORT TASK (ABTS) requests are still not passes to CTL, that is not good
and should be fixed.

user default normal attribute to the current attribute).
This change only fixes a logic error. scterm_clear() used to be
used for terminal reset, but teken uses a general fill function for
that, leaving scterm_clear() only used for initialization and mode
change, when using the user default attribute is correct. It is not
really a terminal function, but needs to sync its changes with the
terminal layer. Syncing of the attribute is currently broken for
terminal reset, but works for initialization and mode change.
some cases of initialization and resetting of the teken cursor position.
(This bad name is consistent with others, but it is too easy to confuse
with scteken_cursor() which goes in the opposite direction.)
The following cases were broken:
- for booting without a syscons console, the teken and sc positions for
ttyv0 were (0, 0), but are supposed to be somewhere in the middle of
the screen (after carefully preserved BIOS and loader messages) (at
least if there is no mode switch that loses the messages).
- after mode switches, the screen is cleared and the cursor is supposed to
be moved to (0, 0), but it was only moved there for sc.
The following case was hacked to work:
- for booting with a syscons console, it was arranged that scteken_init()
for the console could see a nonzero cursor position and adjust, although
this broke the sc seeing it in the non-console case above.
They cannot be used anymore with the userland bits we provide.
Furthermore, their KMS versions support the same hardware.

Some SIMs may not abort them implicitly, that either fail the LUN disable
request or just make us wait for those CCBs forever. With this change
I can successfully disable LUNs on mpt(4). For isp(4), which aborts them
implicitly, this change should be irrelevant.

looked like it might handle reverse attributes, but it actually handles
conversion of attributes in the direction indicated by the new name.
Reverse attributes are just broken.
Rename scteken_attr() to scteken_te_to_sc_attr(). scteken_attr() looked
like it might give teken attributes, but it actually gives sc attributes.
Change scteken_te_to_sc_attr() to return int instead of unsigned int.
u_char would be enough, and it promotes to int, and syscons uses int
or u_short for its attributes everywhere else (u_short holds a shifted
form and it promotes to int too).
This change just does cleanups missed in r56043 17 years ago. The
default attributes were still stored in structs for the purpose of
changing them and passing around pointers to the defaults, but r56043
added another layer that made the defaults invariant and only used for
initialization and reset. Just use the defaults directly. This was
already done for the kernel defaults. The defaults for reverse
attributes aren't actually used, but are ignored in layers that no
longer support them.
- Not set BufferLength caused receive of empty ATIOs.
- CDB length guessing was broken at least for RC16.
- mpt_req_untimeout() was called with wrong req parameter.
- Sense data reporting was broken in several ways.
With this change my LSI7204EP-LC can pass at least basic tests as target.
The code is still far from perfect, but finally I found second hw/driver
after isp(4) that really can work in CAM target mode.

Add support for using mutexes during KDB and shutdown. This is also
required for doing mode-switching during panic for drm-next.
Add new mutex functions mutex_init_witness() and mutex_destroy()
allowing LinuxKPI mutexes to be tracked by witness.
Declare mutex_is_locked() and mutex_is_owned() like inline functions
to get cleaner warnings. These functions are used inside WARN_ON()
statements which might look a bit odd if these functions get fully
expanded.
Give mutexes better debug names through the mutex_name() macro when
WITNESS_ALL is defined. The mutex_name() macro can prefix parts of the

Doing this on physical hosts turns out to be problematic, e.g. see comment
24 and 28 in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211746.
To fix the real underlying issue correctly & thoroughly, IMO we need
a relocatable kernel, but that would require a lot of complicated long
term work: https://reviews.freebsd.org/D9686?id=25414#inline-56969
For now, let's only apply efi_verify_staging_size() to VMs running on
Hyper-V, and restore the old behavior on physical machines since that
has been working for people for a long period of time, though that's
potentially unsafe...
