44d95698ba Some compilers issue a warning when wider integer is casted to narrow

e7a87117d3 The source address selection algorithm tries to apply several rules
for the set of IPv6 addresses. Now each attempt goes into IPv6 statistics,
even if given rule did not won. Change this and take into account only
those rules, that won. Also add accounting for cases, when algorithm
fails to select an address.

32e1d8010b The origin_subst_one() function limits the length of the string to
PATH_MAX after the token substitution.  This is wrong, because
origin_subst_one() performs the substitution on the whole rpath and
similar strings, which contain several pathes separated by colon.  As
result, long (but correct) rpath consisting of many path elements is
rejected by the function.

Correct the problem by rewriting the origin_subst_one() to perform two
passes, first pass to calculate the number of substitutions to be
performed, and second pass to generate the resulting string.  Second
pass allocates the memory for the result based on the count from the
first pass, without enforcing a limit.

e4be3d3ddd Fix N32/N64 register saving by ensuring that all registers resolve
to unique values.

There's some confusion about what the n32 assembler API really is
(since on page 9 of the spec they say that t0-t3 don't exist, then
turn around on page 22 and say that t4-t7 don't exist), and this
doesn't touch that.

NetBSD's version of this file follows the convention I used here, and
is likely to be correct.

This should fix gdb/ptrace.

Note that this change is only in ULE and not in the 4BSD scheduler.

b64478a137 Switch lagg(4) statistics to counter(9).
The lagg(4) is often used to bond high speed links, so basic per-packet +=
on statistics cause cache misses and statistics loss.

Perfect solution would be to convert ifnet(9) to counters(9), but this
requires much more work, and unfortunately ABI change, so temporarily
patch lagg(4) manually.

We store counters in the softc, and once per second push their values
to legacy ifnet counters.

a08f2cf69e Although we perform path compression to reduce the height of the trie and
the number of interior nodes, we have previously created a level zero
interior node at the root of every non-empty trie, even when that node is
not strictly necessary, i.e., it has only one child.  This change is the
second (and final) step in eliminating those unnecessary level zero interior
nodes.  Specifically, it updates the deletion and insertion functions so
that they do not require a level zero interior node at the root of the trie.
For a "buildworld" workload, this change results in a 16.8% reduction in the
number of interior nodes allocated and a similar reduction in the average
execution time for lookup functions.  For example, the average execution
time for a call to vm_radix_lookup_ge() is reduced by 22.9%.

fe52cf5475 Re-factor the code to provide kern_proc_filedesc_out(), kern_proc_out(),
and kern_proc_vmmap_out() functions to output process kinfo structures
to sbuf, to make the code reusable.

The functions are going to be used in the coredump routine to store
procstat info in the core program header notes.

bd3902134c Re-factor coredump routines. For each type of notes an output
function is provided, which is used either to calculate the note size
or output it to sbuf.  On the first pass the notes are registered in a
list and the resulting size is found, on the second pass the list is
traversed outputing notes to sbuf.  For the sbuf a drain routine is
provided that writes data to a core file.

The main goal of the change is to make coredump to write notes
directly to the core file, without preliminary preparing them all in a
memory buffer.  Storing notes in memory is not a problem for the
current, rather small, set of notes we write to the core, but it may
becomes an issue when we start to store procstat notes.

Stop abusing xpt_periph in random plases that really have no periph related

is correctly logged in debug messages as "noperiph".  If at some point we

per-bus, and not a single global instance as xpt_periph now.

Remove multilevel freezing mechanism, implemented to handle specifics of
the ATA/SATA error recovery, when post-reset recovery commands should be
allocated when queues are already full of payload requests.  Instead of
removing frozen CCBs with specified range of priorities from the queue
to provide free openings, use simple hack, allowing explicit CCBs over-
allocation for requests with priority higher (numerically lower) then
CAM_PRIORITY_OOB threshold.

Simplify CCB allocation logic by removing SIM-level allocation queue.
After that SIM-level queue manages only CCBs execution, while allocation
logic is localized within each single device.
