* We need to first call ivp->iv_newstate(), to enqueue the deauth/deassoc
mgmt frame, then flush the tx queue, before actually calling
iwm_release().
* cycling a wlan connection via wpa_cli frontend to wpa_supplicant, by
issuing disconnect and reconnect commandos works quite well.
(There is still an issue when disconnecting/reconnecting too quickly)
* Reassociating or roaming via wpa_supplicant is still broken.

The iwm(4) iwm_poll_bit() function returns 1 on success, and 0 on failure,
whereas the iwl_poll_bit() in Linux iwlwifi returns < 0 on failure.
So the (ret < 0) check ended up ignoring any error returned by
iwm_poll_bit().

The wantresp field in struct iwm_rx_data has never been used for anything,
so we can just delete it.
Apparently struct iwm_sf_cfg_cmd was compiled correctly (using a 32bit
value to represent the enum), but it still seems like a very bad idea to use
an enum type in a __packed struct.

- Use conditional instruction to simplify the ARMv6 vDSO. This means
that we no longer perform any branching. In the failure case, we
simply slide over the assignments of the return values.
The vDSO could be improved even further by using stmia to do
assignments in parallel. Unfortunately, the script used to generate
these is not smart enough for that (yet).
Spotted by: andrew@.
- Make the style of the i686 vDSO more similar to the others by using
decimal literals.
If BIOS performed hand-off to OS with BSP LAPIC in the x2APIC mode,
system usually consumes such configuration without a notice, since
x2APIC is turned on by OS if possible (nop). But if BIOS
simultaneously requested OS to not use x2APIC, code assumption that
that xAPIC is active breaks.
In my opinion, we cannot safely turn off x2APIC if control is passed
in this mode. Make madt.c ignore user or BIOS requests to turn x2APIC
off, and do not check the x2APIC black list. Just trust the config
and try to continue, giving a warning in dmesg.

Reclaimed vnode type is VBAD, so succesful comparision like
devvp->v_type != VREG does not imply that the devvp references
snapshot, it might be due to a reclaimed vnode. Explicitely check the
vnode type.
In the the most important case of ffs_blkfree(), the devfs vnode is
locked and its type is stable. In other cases, if the vnode is
reclaimed right after the check, hopefully the buffer methods return
right error codes.

Bugs in the Python code used to generate this vDSO caused us to
miscompute the register numbers/stack offsets at which addresses of the
system call output arguments were stored.
Together with some other patches, this vDSO allows us to make all of the
cloudlibc unit tests pass.

In order to make CloudABI work on ARMv6, start off by copying over the
sysvec for ARM64 and adjust it to use 32-bit registers. Also add code
for fetching arguments from the stack if needed, as there are fewer
register than on ARM64.
Also import the vDSO that is needed to invoke system calls. This vDSO
uses the intra procedure call register (ip) to store the system call
number. This is a bit simpler than what native FreeBSD does, as FreeBSD
uses r7, while preserving the original r7 into ip.
This sysvec seems to be complete enough to start CloudABI processes.
These processes are capable of linking in the vDSO and are therefore
capable of executing (most?) system calls successfully. Unfortunately,
the biggest show stopper is still that TLS is completely broken:
- The linker used by CloudABI, LLD, still has troubles with some of the
relocations needed for TLS. See LLVM bug 30218 for more details.
- Whereas FreeBSD uses the tpidruro register for TLS, for CloudABI I
want to make use of tpidrurw, so that userspace can modify the base
address directly. This is needed for efficient emulation.
Unfortunately, this register doesn't seem to be preserved across
context switches yet.

some "interesting" values that I can't map to anything useful right now.
* Ensure a default noise floor is set - otherwise the initial scan results
have a noise floor of '0'.
* Fix up the RSSI calculation to be correctly relative to the noise floor.
The RSSI routines return an absolute value in dBm - so fix this up.
* Cap RSSI values appropriately.
* Ensure we pass in a 1/2 dB unit value in to net80211.

Remove redunand i_dev and i_fs pointers, which are available as
ip->i_ump->um_dev and ip->i_ump->um_fs, and reorder members by size to
reduce padding. To compensate added derefences, the most often i_ump
access to differentiate between UFS1 and UFS2 dinode layout is
removed, by addition of the new i_flag IN_UFS2. Overall, this
actually reduces the amount of memory dereferences.
On 64bit machine, original struct inode size is 176, reduced to 152
bytes with the change.
