It doesn't work properly, but this turns out to not be a problem in most
code (code where it is generally uses threads)...
Don't provide misleading information about using it, or programmers
might start wondering why their code doesn't work.

of the structs themselves, so they need special handling. Undo previous
and do the permissions checks explicitly. It would be better to fix the
clockctl ioctls to contain the structs themselves...

- MP-safe drivers provide a mutex to ifmedia that is used to serialize
access to media-related structures / hardware regsiters. Converted
drivers use the new ifmedia_init_with_lock() function for this. The
new name is provided to ease the transition.
- Un-converted drivers continue to call ifmedia_init(), which will supply
a compatibility lock to be used instead. Several media-related entry
points must be aware of this compatibility lock, and are able to acquire
it recursively a limited number of times, if needed. This is a SPIN
mutex with priority IPL_NET.
- This same lock is used to serialize access to PHY registers and other
MII-related data structures.
The PHY drivers are modified to acquire and release the lock, as needed,
and assert the lock is held as a diagnostic aid.
The "usbnet" framework has had an overhaul of its internal locking
protocols to fit in with the media / mii changes, and the drivers adapted.
USB wifi drivers have been changed to provide their own adaptive mutex
to the ifmedia later via a new ieee80211_media_init_with_lock() function.
This is required because the USB drivers need an adaptive mutex.
Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv.
mcx also now calls ifmedia_init_with_lock() because it needs to also use
an adaptive mutex. The mcx driver still needs to be fully converted to
NET_MPSAFE.
Remove old code to free PVEs that should not be there that caused panics
(merge error moving between source trees on my part).
- pmap_destroy(): pmap_remove_all() doesn't work for EPT yet, so need to catch
up on deferred PTP frees manually in the EPT case.
- pp_embedded: Remove it. It's one more variable to go wrong and another
store to be made. Just check for non-zero PTP pointer & non-zero VA
instead.
unmanaged mapping, because there is no existing pmap_page to check in
the shortcut path (it traps).
pv_pte_next(): don't assert pp_embedded because it could have been removed
(during pmap_pp_remove()).
This will mean we automatically get two-finger scrolling on multitouch
pads.
This works, but the scrolling is janky. Why does it eventually move the
mouse cursor (only one finger detected, but two are still there), and why
does it jump up slightly?
