03836978be DTrace: Revert r249367
The following change from illumos brought caused DTrace to
pause in an interactive environment:

3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider

This was not detected during testing because it doesn't
affect scripts.

We shouldn't be changing the environment, especially since the
LD_NOLAZYLOAD option doesn't apply to our (GNU) ld.
Unfortunately the change from upstream was made in such a way
that it is very difficult to separate this change from the
others so, at least for now, it's better to just revert
everything.

11c601447d r249408 and r249436 cause a NULL pointer dereference on the CUBIEBOARD
since it doesn't set the kernel envrionment at all. Work around this
by making sure kern_envp is non-NULL before dereferencing it.

12087a0769 Use the new net80211 method to fetch the node TX power, rather than
directly referencing ni->ni_txpower.

This provides the hardware with a slightly more accurate idea of
the maximum TX power to be using.

This is part of a series to get per-packet TPC to work (better).

ebe15a7b25 Implement a utility function to return the current TX power cap for
the given node.

This takes into account the per-node cap, the ic cap and the
per-channel regulatory caps.

This is designed to replace references to ni_txpower in various net80211
drivers - ni_txpower doesn't necessarily reflect the actual cap for
the given node (eg if the node has the default value of 50dBm (100) and
the administrator has manually configured a lower TX power.)

f1fca82ed5 Add a new set of notes to a process core dump to store procstat data.
The notes format is a header of sizeof(int), which stores the size of
the corresponding data structure to provide some versioning, and data
in the format as it is returned by a related sysctl call.

The userland tools (procstat(1)) will be taught to extract this data,
providing additional info for postmortem analysis.

b7b63db789 Partial MFP4 of 222836:
Only look for FDT partitions if our potential parent is a DISK device.

Excluding direct recursion on the flashmap geoms was insufficient
because it did not prevent the underlying device from being retrieved if
flashmap geoms were further partitioned.

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.

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%.
