556cb98d95 dtrace: correctly map sections to addresses in elf object modules (amd64)
Unlike for modules with dso type, in elf object modules all the sections
have virtual address of zero.  So, it is insufficient to add module base
address to section virtual address (as recorded in section header) to
get section address in kernel memory.
Instead, we should apply the same calculations that are performed by
kernel loaders (in boot code and in kernel) when they lay out sections
in memory.
Also, unlike OpenSolaris, the sections are not collapsed into just .text,
.data and .bss by module loaders, so we need to take additional care
about other sections.

Note that in-kernel symbol-to-address mapping worked just fine, e.g. fbt
provider could correctly find the functions, etc.  It's only in userland
that the mapping in both direction worked incorrectly, e.g. in stack()
output addresses of functions in kernel modules were not translated to
their names.

676799a00d completely ignore zero-sized elf sections in modules of elf object type (amd64)
Current code doesn't check size of elf sections and may perform needless
actions of zero-sized memory allocation and similar.
The bigger issue is that alignment requirement of a zero-sized section
gets effectively applied to the next section if it has smaller alignment
requirement.  But other tools, like gdb and consequently kgdb,
completely ignore zero-sized sections and thus may map symbols to
addresses differently.

Zero-sized sections are not typical in general.
Their typical (only, even) cause in FreeBSD modules is inline assembly that
creates custom sections which is found in pcpu.h and vnet.h.  Mere inclusion
of one of those header files produces a custom section in elf output.
If there is no actual use for the section in a given module, then the
section remains empty.

Better solution is to avoid creating zero-sized sections altogether,
which is in plans.

Preloaded modules are handled in boot code (load_elf_obj.c), while
dynamically loaded modules are handled by kernel (link_elf_obj.c).

dac509311f cpufreq: allocate long-lived buffer for handling of sysctl requests
At present the cpufreq sysctl handler for current level setting would
allocate and deallocate a temporary buffer of 24KB even to handle a
read-only query.  This puts unnecessary load on memory subsystem when
current level is checked frequently, e.g. when the likes of powerd
and system monitoring software are running.
Change the strategy to allocating a long-lived buffer for handling the
requests.

6eae6892da Rework how device memory is allocated on the s3c24x0 CPU's.
The device virtual addresses are now able to be allocated at runtime rather
than from the static pmap_devmap at boot. The only exception is memory
required before we have had a chance to dynamically allocate it.

While here reduce the space between the statically allocated devices by
reducing the distance between the virtual addresses.

4dc88ebedf Add BSD grep to the base system and make it our default grep.
Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC),
              lower memory usage than GNU grep, GNU compatibility,
              BSD license.

TODO:         Performance is somewhat behind GNU grep but it is only
              significant for bigger searches.  The reason is complex, the
              most important factor is that GNU grep uses lots of
              optimizations to improve the speed of the regex library.
              First, we need a modern regex library (practically by adopting
              TRE), add support for GNU-style non-standard regexes and then
              reevalute the performance issues and look for bottlenecks.  In
              the meantime, for those, who need better performance, it is
              possible to build GNU grep by setting WITH_GNU_GREP.

7d54a05ac8 Correctly setup LDADD with regards to libstand. The submitter points
out that "on amd64, libstand.a is compiled for i386, but is still installed
under ${WORLDTMP}/usr/lib instead of ${WORLDTMP}/usr/lib32.  Even if it
would be installed there, ld on amd64 is set up incorrectly with a
${TOOLS_PREFIX}/usr/lib/i386 default path, so it wouldn't link.  The reason
it does link under gcc is that gcc passes -L${WORLDTMP}/usr/lib twice,
even for -m32 builds, which is also incorrect, but accidentally works in
this case."

0f68c374aa Add regression tests for newsyslog. These are far from a complete
test of newsyslog, as they were mainly made to test 'newsyslog -t',
but they do test the basic functionality.

The test 'framework' was based on dds@'s code in
src/tools/regression/bin/mv/.

Note that currently these tests are not fully correct for the
non-timestamp based rotation case, as it seems like newsyslog actually
by default keeps a file too much around.

872e964d07 Add support for creating the archived log filenames using a time-stamp
instead of the traditional simple counter.

Using the time-stamp based file-names, once a log file is archived, it
will not change name until it is deleted.  This means that many backup
systems will only perform one backup of the archived log file, instead
for performing a new backup of the logfile upon each logfile rotation.

This implementation is separate from the patches in the mentioned PR,
as I wasn't aware of the existence of the PR until after I had
implemented the same functionality as the patches in the PR provide.
Unlike the PR, this new code does honor the 'log count' in
newsyslog.conf so old logfiles are deleted.  This new code does not
currently support never deleting the archived logfiles.
