tested and is unfinished. However, I've tested my version,
it works okay. As before it is unfinished: timeout aren't
driven by TCP session state. To enable the HASH_ALL mode,
one needs in kernel config:
options FLOWTABLE_HASH_ALL
o Reduce the alignment on flentry to 64 bytes. Without
the FLOWTABLE_HASH_ALL option, twice less memory would
be consumed by flows.
o API to ip_output()/ip6_output() got even more thin: 1 liner.
o Remove unused unions. Simply use fle->f_key[].
o Merge all IPv4 code into flowtable_lookup_ipv4(), and do same
flowtable_lookup_ipv6(). Stop copying data to on stack
sockaddr structures, simply use key[] on stack.
o Move code from flowtable_lookup_common() that actually works
on insertion into flowtable_insert().

fdgrowtable() now only reallocates fd_map when necessary.
This fixes fdgrowtable() to use the same logic as fdescfree() for
when to free the fd_map. The logic in fdescfree() is intended to
not free the initial static allocation, however the fd_map grows
at a slower rate than the table does. The table is intended to hold
20 fd, but its initial map has many more slots than 20. The slot
sizing causes NDSLOTS(20) through NDSLOTS(63) to be 1 which matches
NDSLOTS(20), so fdescfree() was assuming that the fd_map was still
the initial allocation and not freeing it.
This partially reverts r244510 by reintroducing some of the logic
it removed in fdgrowtable().

Should fix the build with g++/libstdc++.
This is what we used to do prior the import of atf 0.20 and the build worked
just fine with both libstdc++ and libc++. Still investigating how to properly
fix this upstream so that we do not hit the same issue on the next import.
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.
The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing
any possibility of recovering from the error.
Also, double the timeout to 2 seconds. Despite what the SD spec says about
all transactions completing in 250ms or less, I have a card which sometimes
takes more than a second to complete a write.
NB: If the zfsboot variables ($ZFSBOOT_*) are set, a script is
assumed to want zfsboot module instead of scriptedpart module.

This is to let Kyua descend into any tests that may have been installed by
ports under /usr/local/tests when running the test suite from /usr/tests.
Some ports (namely those that build Kyua) already install test programs
into /usr/local/tests. Just make sure to select the TEST option while

matching 'compatible' property. This probably has a short half-life (as
do most of the fdt_ functions), but it helps solve some near-term needs
until we work out the larger problems of device instantiation order
versus the order of things in the fdt data.
If the hardware is not in a good state (like maybe clocks aren't running
because of a configuration glitch) its timeout clock may also not work
correctly, and the next command sent will hang that thread forever. The
thread in question is usually the one and only thread (at init time) or
a bio queue worker thread whose lockup will eventually lead to the whole
system locking up when it runs out of buffers.
No sd card command should take longer than 250ms. This new code establishes
a 1-second timeout to allow plenty of safety margin over that.
Normally it never needs to wait here at all; waiting is done at the end
of the prior command. When doing a crash dump, the normal interrupt
mechanism isn't used; instead the interrupt handler is called repeatedly
in a polling-like manner. This can subvert hardware-specific drivers
and lead to trying to start a new command while the previous command is
still busy on the bus. Since the SD spec says the longest a card can
take to execute any command is 250ms, use that as a timeout.

Attempt to demote the superpage if trying to pmap_enter() on
one. Panic only when the particular superpage should
no longer exist for that pmap and address.
Because pmap_enter_locked() is called from few different functions
some redundancy in superpage promotion attempts can be observed.
Hence, avoid promotion in pmap_enter_object() (if the object can
be mapped by superpage it will be handled by pmap_enter_object()
itself) and also do not waste time in pmap_enter_quick().
From now on the promotion will be performed only in pmap_enter().
It was possible to create RW superpage mapping even if
the base pages were RO due to wrong setting of the prot
flag passed to pmap_map_section().
Promotion attempt should be canceled in case of attributes
mismatch between any two base pages. Since we still use
pv_flags to maintain permission to write (PVF_WRITE) and
wired status (PVF_WIRED) for a page, it is also necessary
to take those variables into account.
