r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

ThinkPad PrivacyGuard is a built-in toggleable privacy filter that
restricts viewing angles when on. It is an available on some new
ThinkPad models such as the X1 Carbon 7th gen (as an optional HW
upgrade).
The privacy filter can be enabled/disabled via an ACPI call. This commit
adds a sysctl under dev.acpi_ibm that allows for getting and setting the
PrivacyGuard state.

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).
No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
Add support for newer Thinkpad models with id LEN0268. Was tested on
Thinkpad T480 and ThinkPad X1 Yoga 2nd gen.

Add a few intermediate casts to intptr_t to suppress "cast to pointer
from integer of different size" warnings from gcc. In this case, the
'arg2' part of SYSCTL_HANDLER_ARGS is used to pass in a pointer, via an
intermediate intmax_t, so no information is lost.

- Attach only to WMI devices that provide supported GUIDs. HP Spectre x360
has two WMI devices, only one of which provides the GUIDs.
- Pass proper device to ACPI_WMI_REMOVE_EVENT_HANDLER() on detach.
- Improve error WMI handling separating status and data paths. This allows
to hide sysctls not supported by specific hardware/BIOS.
- Improve CMI block parser to make it work on HP Spectre x360 laptop.
- In verbose mode log all unknown events to help futher improvements.
Comparing to the Linux driver there is still one missing feature.
The Linux driver finds and enables "Embedded Controller" item in
the 0x11 group if it's not enabled yet.
I tested the new method, Torfinn Ingolfsen tested the old method
and helped to fix several bugs in the earlier versions of the patch.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.
This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.

Without this booting the VSATV102 causes the blue "working" led to turn
off when the kernel starts up. With this the led (which is turned on by
the firmware) stays on since that's the default state specified in the FDT.
Expanded the meaning of the led_create_state state parameter in order
to implement support for "keep". The original values were:
== 0 Off
!= 0 On
The new values are:
== -1 don't change / keep current setting
== 0 Off
!= -1 && != 0 On
This should have no effect on acpi_asus_attach which only calls
led_create_state with state set to 1. Updated acpi_ibm_attach
in order to avoid surprises.

- Wrong integer type was specified.
- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.
- Logical OR where binary OR was expected.
- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.
- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.
- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.
- Updated "EXAMPLES" section in SYSCTL manual page.

of separate ACPI device.
On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN,
Bluetooth, LCD backlight, camera, cardreader and touchpad.
On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth,
