The command was checking local/remote system uptime, so rename the script to
match its function and to avoid confusion
The controlling variable in /etc/periodic.conf has been renamed from
daily_status_rwho_enable to daily_status_uptime_enable.

MK_USB != no
Add the manpages to OptionalObsoleteFiles.inc
As a side-effect, this also fixes installworld with MK_USB == no
X-MFC with: r290128

Other sidenotes:
- Remove unused variables with main(..)
- Convert errx/exit with -1 to errx/exit with 1
- Fix a bogus test in try_directory_open
(expected_errno == expected_errno -> errno == expected_errno) [*]
- Fix some warnings related to discarded qualifiers
- Remove a bogus else-statement at the end of check_mmap_exec(..) in the
successful case. mmap(2), POSIX, Linux, etc all don't state what the
behavior is when mixing O_WRONLY + PROT_EXEC, so assume success for now to
get the test program to pass again.

Allows DMA from/to arbitrary KVA or physical address. /dev/ioat_test
must be enabled by root and is only R/W root, so this is approximately
as dangerous as /dev/mem and /dev/kmem.

listen, and connect. The listen program is a simple server that
accepts and closes sockets, until a fixed limit, then sets the listen
queue to 0 and counts how many remaining connections it processes.
The connect program repeatedly opens connections and closes them
serving as the driver for the listen program.

The IOAT hardware supports writing a 64-bit pattern to some destination
buffer. The same limitations on buffer length apply as for copy
operations. Throughput is a bit higher (probably because fill does not
have to spend bandwidth reading from a source in memory).
Support for testing Block Fill has been added to ioatcontrol(8) and the
ioat_test device. ioatcontrol(8) accepts the '-f' flag, which tests
Block Fill. (If the flag is omitted, the tool tests copy by default.)
The '-V' flag, in conjunction with '-f', verifies that buffers are
filled in the expected pattern.
Tested on: Broadwell DE (Xeon D-1500)

The test logic now preallocates memory before running the test.
The buffer size is now configurable. Post-copy verification is
configurable. The number of copies to chain into one transaction (one
interrupt) is configurable.
A 'duration' mode is added, which repeats the test until the duration
has elapsed, reporting the B/s and transactions completed.
ioatcontrol.8 has been updated to document the new arguments.
Initial limits (on this particular Broadwell-DE) (and when the
interrupts are working) seem to be: 256 interrupts/sec or ~6 GB/s,
whichever limit is more restrictive.
Unfortunately, it seems the interrupt-reset handling on Broadwell isn't
working as intended. That will be fixed in a later commit.

Extend OptionalObsoleteFiles.inc to delete all lib32 files when MK_LIB32 is
set to no on a system that previously had lib32 libraries installed.
Also, to prevent "make delete-old-dirs" from always deleting lib32 directories
after an installworld, move the lib32 subtree to its own mtree file that only
gets applied when MK_LIB32=yes.
Test: Ran "make delete-old" and "make delete-old-libs" on a system that never
had MK_LIB32 enabled, and on a system where MK_LIB32 was enabled and later
disabled. Did this both on amd64 and powerpc64.
Test: Ran "make tinderbox" without errors.

- Make the requirements more complete for the testcases
- Detect prerequisites so the tests won't fail (zfs.ko is loaded, zpool(1)
is available, ACL support is enabled with UFS, etc).
- Work with temporary files/directories/mountpoints that work with atf/kyua
- Limit the testcases to work on temporary filesystems to reduce tainting the
test host

Some other highlights:
- Convert the testcases over to ATF
- Don't use hardcoded paths to /tmp (which violate the ATF/kyua samdbox); use
mkstemp to generate temporary paths for non-SHM_ANON shm objects.

Compare the fields that the AMD [1] and Intel [2] specs say will be
set once fnstenv returns.
Not all amd64 capable processors zero out the env.__x87.__other field
(example: AMD Opteron 6308). The AMD64/x64 specs aren't explicit on what the
env.__x87.__other field will contain after fnstenv is executed, so the values
in env.__x87.__other could be filled with arbitrary data depending on how the
CPU-specific implementation of fnstenv.

Also note that these env-only vars can be specified on the command line.
This fixes the dependent options that are env-only (such as WITH_META_MODE
and WITH_AUTO_OBJ) to properly display their dependencies.

connectivity interact with the net80211 stack.
Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.
Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:
- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
driver about any changes: number of wlan(4) interfaces, number of them
in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
driver experiences errors and can not attribute them to any specific
interface, driver updates ic_oerrors or ic_ierrors counters.
Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
now provided by net.wlan.devices sysctl.
Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann,
Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in
testing.

I/OAT is also referred to as Crystal Beach DMA and is a Platform Storage
Extension (PSE) on some Intel server platforms.
This driver currently supports DMA descriptors only and is part of a
larger effort to upstream an interconnect between multiple systems using
the Non-Transparent Bridge (NTB) PSE.
For now, this driver is only built on AMD64 platforms. It may be ported
to work on i386 later, if that is desired. The hardware is exclusive to
x86.
Further documentation on ioat(4), including API documentation and usage,
can be found in the new manual page.
Bring in a test tool, ioatcontrol(8), in tools/tools/ioat. The test
tool is not hooked up to the build and is not intended for end users.
