- Remove two excessive and slow register reads from isp_intr(). Instead
of rereading value every time, assume that registers contain what we have
written there.
- Avoid sequential search through 4096 array elements when looking for
command tag. Use hash of lists to store active tags separately from free
ones and so greatly speedup the searches.

the first byte of the line number program. The hard-coded constants
previously here (4 + 2 + 4) were correct only for 32-bit DWARF.

type-less root (.) entries as seen in a couple ports, and corrects a bug
in -N that caused expanded Subversion $FreeBSD$ strings in comments to
be processed as /etc/group entries.
Includes one trivial portability fix (including <stdint.h> in three
files) that has been submitted upstream but not yet committed.

The order of releasing resources in mlxen was wrong, which caused
panic on reload of the module.
conf_ctx list should be released before stat_ctx list, otherwise
the leafs in conf_ctx list won't be released because of the dependancy.
The fix is to change the order of the releases.

The MDIO bus frequency is configured as a divisor off of the MDIO bus
reference clock. For the AR9344 and later, the MDIO bus frequency can
be faster than normal (ie, up to 100MHz) and thus a static divisor may
not be very applicable.
So, for those boards that may require an actual frequency to be selected
regardless of what crazy stuff the vendor throws in uboot, one can now
set the MDIO bus frequency. It uses the MDIO frequency and the target
frequency to choose a divisor that doesn't exceed the target frequency.
By default it will choose:
* DIV_28 on everything; except
* DIV_58 on the AR9344 to be conservative.
Whilst I'm here, add some comments about the defaults being not quite
right. For the other internal switch devices (like the AR933x, AR724x)
the divisor can be higher - it's internal and the reference MDIO clock
is much lower than 100MHz.
The divisor tables and loop code is inspired from Linux/OpenWRT. It's very
simple; I didn't feel that reimplementing it would yield a substantially
different solution.
Tested:
* AR9331 (mips24k)
* AR9344 (mips74k)

This is generally handled by the fact that the list of filesystem objects
is sorted, but this sorting is broken by code which moves .so files ahead
(so that they're present before any binaries which use them)... that code
also moved .so files ahead of directories, which is a problem for upgrading
to 10.0 where there's a new directory containing new .so files.

runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary. (This is similar to what GNU libstdc++ does
in its default configuration.) The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.

that implies that some driver asked for a sync (probably incorrectly) and
nothing was done.
Usual symptoms are messages like
rn_delete: inconsistent annotation
rn_addmask: mask impossibly already in tree
or inability to flush/delete particular prefix in ipfw table.
Changes:
* Assume 32 bytes as maximum radix key length
* Remove rn_init()
* Statically allocate rn_ones/rn_zeroes
* Make separate mask tree for each "normal" tree instead of system global one
* Remove "optimization" on masks reusage and key zeroying
* Change rn_addmask() arguments to accept tree pointer (no users in base)

- Take BIO lock in biodone() only when there is no completion callback set
and so we should wake up thread waiting in biowait().
- Remove msleep() timeout from biowait(). It was added 11 years ago, when
there was no locks used, and it should not be needed any more.
Move tq_enqueue() call out of the queue lock for known handlers (actually
I have found no others in the base system). This reduces queue lock hold
time and congestion spinning under active multithreaded enqueuing.
Introduce new function devstat_end_transaction_bio_bt(), adding new argument
to specify present time. Use this function to move binuptime() out of lock,
substantially reducing lock congestion when slow timecounter is used.
