86570b7a27 - Don't invalidate jnewblks immediately upon discovering that the block
will be removed.  Permit the journal to proceed so that we don't leave
   a rollback in a cg for a very long time as this can cause terrible perf
   problems in low memory situations.

0c7a0c810c Implement atomic_load_acq_64(9) and atomic_store_rel_64(9) for i386. These
functions are implemented with CMPXCHG8B instruction where it is available,
i. e., all Pentium-class and later processors.  Note this instruction is
also used for atomic_store_rel_64() because a simple XCHG-like instruction
for 64-bit memory access does not exist, unfortunately.  If the processor
lacks the instruction, i. e., 80486-class CPUs, two 32-bit load/store are
performed with interrupt temporarily disabled, assuming it does not support
SMP.  Although this assumption may be little naive, it is true in reality.
This implementation is inspired by Linux.

This fixes a long standing bug in mxge(4) where "ifconfig mxge0 $IP"
did not bring the interface into a RUNNING state, like it does on
most (all?) other FreeBSD NIC drivers.

Thanks to gnn for mentioning the bug, and yongari for pointing out that

c902a38c4a Allow strerror(0) and strerror_r(0, ...).
Of course, strerror_r() may still fail with ERANGE.

Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.

bb9f2459b8 Important update for the igb driver:
- Add the change made in em to the actual unrefreshed number
    of descriptors is used as a basis in rxeof on the way out
    to determine if more refresh is needed. NOTE: there is a
    difference in the ring setup in igb, this is not accidental,
    it is necessitated by hardware behavior, when you reset the
    newer adapters it will not let you write RDH, it ALWAYS sets
    it to 0. Thus the way em does it is not possible.
  - Change the sysctl handling of flow control, it will now make
    the change dynamically when the variable setting changes rather
    than requiring a reset.
  - Change the eee sysctl naming, validation found the old unintuitive :)
  - Last but not least, some important performance tweaks in the TX
    path, I found that UDP behavior could be drastically hindered or
    improved with just small changes in the start loop. What I have
    here is what testing has shown to be the best overall. Its interesting
    to note that changing the clean threshold to start at a full half of
    the ring, made a BIG difference in performance.  I hope that this
    will prove to be advantageous for most workloads.

cddd210098 * Add the readline(3) API to libedit. The libedit versions of
{readline,history}.h are in /usr/include/edit so as to not conflict with
  the GNU libreadline versions.  To use the libedit readline(3) one should
  add "-I/usr/include/edit" to their Makefile
  (spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree).

* Enable its use in the BSD licensed utilities that support readline(3).

* To make it easier to sync libedit development with NetBSD, histedit.h
  is moved into libedit's directory as history shows shown we keep merging
  it into that location.

48e4efea84 Lower the bar for ACPI-fast on real machines slightly. Empirical evidences
show that there are perfectly working PM timers with occasional "hiccups",
probably because of an SMI.  Now we ignore the maximum if it happens once in

32bac9120d Add initial jumbo frame support for BCM5714/BCM5715 and BCM5780.
Unlike other controllers which have more advanced jumbo support,
these controllers have one send ring, one standard receive producer
ring and one receive return ring. In order to receive jumbo frames
on the controllers, driver now will increase Rx buffer size to 9k.
Two Rx modes are supported on these controllers and I chose
standard Rx BDs over extended Rx BDs. The extended Rx BD mode
allows up to 4 segmentations for each Rx BDs such that kernel does
not have to allocate large buffer of contiguous memory for
receiving. The extended Rx BD mode is already used on controllers
that have separate jumbo receive ring. However, using extended Rx
BDs on BCM5714/BCM5715/BCM5780 reduces the number of Rx BDs to 256
entries which in turn may reduce the performance.  Also UMA backed
page allocator for jumbo frame returns contiguous memory so using
extended Rx BD has no advantage on FreeBSD unless highly customized
local allocator implemented in driver is used.
To use jumbo buffers in standard receive ring, Rx buffer allocation
handler was changed to allocate MJUM9BYTES sized mbuf.

4fde1ce654 Add the ability to manage the state of write caching when the battery
back-up is missing or dead.  The current state of this field is reported
in 'mfiutil cache <volume>' and can be adjusted via
'mfiutil cache <volume> bad-bbu-write-cache <enable|disable>'.  This
setting should generally be disabled to avoid data loss.

d61e085348 Extend the DDB command "watchdog" with the ability to specify a timeout
value.

The timeout is expressed in the form T(N) = (2^N * nanoseconds) and can
be easilly extracted from the watchdog interface as a WD_TO_* macro.
That new functionality is supposed to fix re-entering the kernel from DDB
re-enabling the watchdog again (previously disabled) and also offer the
possibility to break for deadlocked DDB commands.

Please note that retro-compatibility is retained.

Make fdt default on arm and powerpc.

This now includes cross compiled targets, where before we tried to

Also, move the lists of default yes and no options to a variable.

In general, only build tools should get this treatment in bsd.own.mk.
Also, the use of TARGET* in the bsd.*mk files is discouraged, but
necessary here due to the ordering of things in buildworld.  We make
the native case work by testing MACHINE_ARCH after TARGET_ARCH.

a6f6f69850 if_arge has had a strange bug that only appears during high traffic
levels. TX would hang, RX wouldn't. A bit of digging showed the interface
send queue was full, but IFF_DRV_OACTIVE was clear and the hardware TX
queue was empty.

It turns out that there wasn't a check to drain the interface send
queue once hardware TX had completed, so if the interface send queue
had filled up in the meantime, subsequent packets would be dropped
by the higher layers and if_start (and thus arge_start()) would never
be called.

The fix is simple - call arge_start_locked() in the software interrupt
handler after the hardware TX queue has been handled or a TX underrun
occured. This way the interface send queue gets drained.
