terms "flugelhorn" and "bullfrog", while also good, are less well-known

LAPIC timer iinterrupt when TSC reaches the value written to the
IA32_TSC_DEADLINE MSR. To arm or reset the timer in deadline mode, a
single non-serializing MSR write is enough. This is an advance from
the one-shot mode of LAPIC, where timer operated with the FSB
frequency and required two (serialized in case of xAPIC) writes to the
APIC registers.
The LVT_TIMER register value is cached to avoid unneeded writes in the
deadline mode. Unused arguments to specify period (which is passed in
struct lapic as la_timer_period) and interrupt enable (which is always
enabled) are removed from lapic_timer_{oneshot,periodic,deadline}
functions. Instead, special lapic_timer_oneshot_nointr() function for
interrupt-less one-shot calibration is added.

program without listening to the devd socket for all events. Define
two new pseudo variables $*, the entire event from devctl and $_,
the entire event without the type character, since it might be easier
to use in some circumstances.
only the first one will actually work and all the others just result in
errors (which would get printed but otherwise ignored).
Instead, wait until we make a choice of which interface will be used to
mount the rootfs, and install the default route associated with it (if any).
After doing the md_mount() call to obtain the needed info, remove the
default route again, and transcribe the route info into the nfs_diskless
structure. If the system eventually chooses to mount the nfs rootfs, the
default route will be installed again when the nfs_diskless code
re-initializes the interface.
The theory here is that since we can only have one default route, the one
most likely to be correct for mounting the rootfs is the one that was
delivered along with the rootpath option.
bootp/dhcp server doesn't provide a router option. Doing so prevents
setting defaultrouter=<ip> in rc.conf (it fails because there's already
a bogus default route installed by bootpc_init).
When an admin wants to use this style of proxy arp on an interface, the
proper mechanism is to set the "use-lease-addr-for-default-route" flag
in the dhcp server config. That causes the lease address to be delivered
in the routers option, and the normal handling of the routers option will
then install the self-ip as the default route.

server (and not when it came from a fallback method such as the ROOTDEVNAME
option). This makes the code in bootpc_init() choose the first interface
that provided a rootpath name. Previously it was choosing the first
interface that got an IP address, which could be on a different and
potentially unreachable subnet than the server providing the rootfs.
If the rootpath name actually does come from a fallback source, then the
code continues to use the first interface in the list that got configured.

[libcxx] Enable noexcept for GCC 4.6 and greater
Summary:
This patch allows GCC 4.6 and above to use `noexcept` as opposed to
`throw()`.
Is it an ABI safe change to suddenly switch on `noexcept`? I imagine
it must be because it's disabled in w/ clang in C++03 but not C++11.

into per-mount taskqueue with the private taskqueue processing thread.
This allows to drain the taskqueue on unmount, to ensure that all
TRIMs are finished before mount structures are freed.
But just draining the taskqueue where TRIM biodone geom-up completions
are processed is not enough, since ffs_blkfree(), called by the task,
might result in more writes. Count inflight delayed blkfree's and
pause() unmount until the counter drains as well.

with libc++, which is also C++11. Also change one _Static_assert (which
is really C11) back into static_assert, like upstream.
This should help when compiling libcxxrt with newer versions of gcc,
which refuse to recognize any form of static assertions, if not
compiling for C++11 or higher.
While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++
headers outside the source tree.
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE. The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl. M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.
Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.
Update netmap_get_mbuf to not pass M_NOFREE to m_getcl. It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.
