Please note the following changes:
- zio_ioctl has lost its priority parameter and now TRIM is executed
with 'now' priority
- some knobs are gone and some new knobs are added; not all of them are
exposed as tunables / sysctls yet

943 zio_interrupt ends up calling taskq_dispatch with TQ_SLEEP
illumos/illumos-gate@5aeb94743e
Essentially FreeBSD taskqueues already operate in a mode that
was added to Illumos with taskq_dispatch_ent change.
We even exposed the superior FreeBSD interface as taskq_dispatch_safe.
Now we just rename taskq_dispatch_safe to taskq_dispatch_ent and
struct struct ostask to taskq_ent_t, so that code differences will be
minimal.
After this change sys/cddl/compat/opensolaris/sys/taskq.h header is no
longer needed.
Note that this commit is not an MFV because the upstream change was not
individually committed to the vendor area.

Mention that the automatic mode switch from umass to u3g needed by some
devices does not work unless the driver is loaded before the device is
connected.

The new macros are implemented in terms of SDT_PROBE_DEFINE and SDT_PROBE.
Probes defined in this way will appear under SDT provider named "sdt".
Parameter types are exposed via SDT_PROBE_ARGTYPE.
This is something that illumos does not have by default.
This kind of SDT probes is already present in ZFS code, so those probes
will now be available if KDTRACE_HOOKS options is enabled.
A potential future illumos compatibility enhancement is to encode a provider
name as a prefix in a probe name.

In its stead use the Solaris / illumos approach of emulating '-' (dash)
in probe names with '__' (two consecutive underscores).

Table is 22 bits, with the bit 31 being the interrupt-on-completion
bit.
OpenBSD and UEFI set this bit, resulting in large block i/o lengths
being sent to bhyve and coredumping the process. Fix by masking off
the relevant 22 bits when using the DBC field as a length.

callable from the kernel.
Right now vn_sendfile() can't be called from anything other than
a syscall handler _and_ return the number of bytes queued.
This simply moves the copyout() to do_sendfile() so that any kernel
code can initiate vn_sendfile() outside of a syscall context.

This lock gets deleted in sys/netpfil/ipfw/ip_fw2.c:vnet_ipfw_uninit().
Therefore, vnet_ipfw_nat_uninit() *must* be called before vnet_ipfw_uninit(),
but this doesn't always happen, because the VNET_SYSINIT order is the same for both functions.
In sys/net/netpfil/ipfw/ip_fw2.c and sys/net/netpfil/ipfw/ip_fw_nat.c,
IPFW_SI_SUB_FIREWALL == IPFW_NAT_SI_SUB_FIREWALL == SI_SUB_PROTO_IFATTACHDOMAIN
and
IPFW_MODULE_ORDER == IPFW_NAT_MODULE_ORDER
Consequently, if VIMAGE is enabled, and jails are created and destroyed,
the system sometimes crashes, because we are trying to use a deleted lock.
To reproduce the problem:
(1) Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS,
INVARIANTS.
(2) Run this command in a loop:
jail -l -u root -c path=/ name=foo persist vnet && jexec foo ifconfig lo0 127.0.0.1/8 && jail -r foo
(see http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html )
Fix the problem by increasing the value of IPFW_NAT_SI_SUB_FIREWALL,
so that vnet_ipfw_nat_uninit() runs after vnet_ipfw_uninit().
it is all in the one place again. Rename libc/iconv/iconv.c to
bsd_iconv.c. Compile the wrappers into libc.a so that WITHOUT_DYNAMICROOT

bhyve supports a single timer block with 8 timers. The timers are all 32-bit
and capable of being operated in periodic mode. All timers support interrupt
delivery using MSI. Timers 0 and 1 also support legacy interrupt routing.
At the moment the timers are not connected to any ioapic pins but that will
be addressed in a subsequent commit.
This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).
In r208160, sctp_it_ctl was made a global variable, across all VNETs.
However, sctp_init() is called for every VNET that is created. This results
in the same global mutexes which are part of sctp_it_ctl being initialized. This can result
in crashes if many jails are created.
To reproduce the problem:
(1) Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS,
INVARIANTS.
(2) Run this command in a loop:
jail -l -u root -c path=/ name=foo persist vnet && jexec foo ifconfig lo0 127.0.0.1/8 && jail -r foo
(see http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html )
Witness will warn about the same mutex being initialized.
Fix the problem by only initializing these mutexes in the default VNET.

Convert some versions of EXTRACT_{16,32,64}BITS() to inline functions.
It removes the vast majority of strict-aliasing warnings from GCC.
