c6bd67d9d0 Add a make target (smilint) for running smilint tool against BMIBS
Running smilint against MIB definitions is useful in finding
functional problems with MIB definitions/descriptions.

This is inspired by the smilint targets defined in
usr.sbin/bsnmpd/modules/{snmp_hostres,snmp_mibII}/Makefile

Document all of the variables that are involved in running the
smilint target, as well as all of the prerequisites to running
it.

339efd75a4 Add a new socket option SO_TS_CLOCK to pick from several different clock
sources to return timestamps when SO_TIMESTAMP is enabled. Two additional
clock sources are:

o nanosecond resolution realtime clock (equivalent of CLOCK_REALTIME);
o nanosecond resolution monotonic clock (equivalent of CLOCK_MONOTONIC).

In addition to this, this option provides unified interface to get bintime
(equivalent of using SO_BINTIME), except it also supported with IPv6 where
SO_BINTIME has never been supported. The long term plan is to depreciate
SO_BINTIME and move everything to using SO_TS_CLOCK.

Idea for this enhancement has been briefly discussed on the Net session
during dev summit in Ottawa last June and the general input was positive.

This change is believed to benefit network benchmarks/profiling as well
as other scenarios where precise time of arrival measurement is necessary.

There are two regression test cases as part of this commit: one extends unix
domain test code (unix_cmsg) to test new SCM_XXX types and another one
implementis totally new test case which exchanges UDP packets between two
processes using both conventional methods (i.e. calling clock_gettime(2)
before recv(2) and after send(2)), as well as using setsockopt()+recv() in
receive path. The resulting delays are checked for sanity for all supported
clock types.

it into pmap-v4.h where they are used.  Other than those few lines of
support for different MMU types, nothing in cpuconf.h has been used in our

The file existed to set up a variety of symbols to describe the
architecture.  Over the past few years we have converted all of our source
to use the new architecture symbols standardized by ARM Inc, and predefined
by both clang and gcc.

eb6ac6f9db Make CTL frontends report kern_data_resid for under-/overruns.
It seems like kern_data_resid was never really implemented.  This change
finally does it.  Now frontends update this field while transferring data,
while CTL/backends getting it can more flexibly handle the result.
At this point behavior should not change significantly, still reporting
errors on write overrun, but that may be changed later, if we decide so.

CAM target frontend still does not properly handle overruns due to CAM API
limitations.  We may need to add some fields to struct ccb_accept_tio to
pass information about initiator requested transfer size(s).

662e30fca3 [gpioths] new driver for temperature/humidity sensor DHT11
This patch adds driver for temperature/humidity sensor connected via GPIO.
To compile it into kernel add "device gpioths". To activate driver, use
hints (.at and .pins) for gpiobus. As result it will provide temperature &
humidity values via sysctl.

DHT11 is cheap & popular temperature/humidity sensor used via GPIO on ARM
or MIPS devices like Raspberry Pi or Onion Omega.

ebf8934652 rtld: do not rely on a populated GOT on amd64
On rela architectures GNU BFD ld and gold store the relocation addend
in GOT entries (in addition to the relocation's r_addend field).
rtld previously relied on this to access its own _DYNAMIC symbol in
order to apply its own relocations.

However, recording addends in the GOT is not specified by the ABI,
and some versions of LLVM's LLD linker leave the GOT uninitialized on
rela architectures.

BFD ld does not populate the GOT on sparc64, and sparc64 rtld has a
machine-dependent rtld_dynamic_addr() function that returns the
_DYNAMIC address. Use the same approach on amd64, obtaining the %rip-
relative _DYNAMIC address following a suggestion from Rafael Espíndola.

Architectures other than amd64 should be addressed in future work.

c2655a40a7 Avoid unnecessary page lookups in vm_object_madvise().
vm_object_madvise() is frequently used to apply advice to a contiguous
set of pages in an object with no backing object. Optimize this case by
skipping non-resident subranges in constant time, and by iterating over
resident pages using the object memq, thus avoiding radix tree lookups on
each page index in the specified range.

While here, move MADV_WILLNEED handling to vm_page_advise(), and rename the
"advise" parameter to vm_object_madvise() to "advice."
