- Replace tunables-only hw.psm.synaptics_support, hw.psm.trackpoint_support,
and hw.psm.elantech_support with respective sysctls declared with
CTLFLAG_TUN. It simplifies checking them in userland, also makes them
easier to get discovered by user
- Get rid of debug.psm.loglevel and hw.psm.tap_enabled TUNABLE_INT

Elantech trackpads are found in some laptops like the Asus UX31E. They
are "synaptics compatible" but use a slightly different protocol.
Elantech hardware support is not enabled by default and just like
Synaptic or TrackPoint devices it should be enabled by setting
tunable, in this case hw.psm.elantech_support, to non-zero value

On some architectures, u_long isn't large enough for resource definitions.
Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but
type `long' is only 32-bit. This extends rman's resources to uintmax_t. With
this change, any resource can feasibly be placed anywhere in physical memory
(within the constraints of the driver).
Why uintmax_t and not something machine dependent, or uint64_t? Though it's
possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on
32-bit architectures. 64-bit architectures should have plenty of RAM to absorb
the increase on resource sizes if and when this occurs, and the number of
resources on memory-constrained systems should be sufficiently small as to not
pose a drastic overhead. That being said, uintmax_t was chosen for source
clarity. If it's specified as uint64_t, all printf()-like calls would either
need casts to uintmax_t, or be littered with PRI*64 macros. Casts to uintmax_t
aren't horrible, but it would also bake into the API for
resource_list_print_type() either a hidden assumption that entries get cast to
uintmax_t for printing, or these calls would need the PRI*64 macros. Since
source code is meant to be read more often than written, I chose the clearest
path of simply using uintmax_t.
Tested on a PowerPC p5020-based board, which places all device resources in
0xfxxxxxxxx, and has 8GB RAM.

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

which is default. It was broken in r281441.
It appears that set_trackpoint_parameters() call on resume disables the
mouse. So, we need not call it on resume if hw.psm.trackpoint_support=0.
The problem is that the probe functions are used both for probing and
for reiniting on resume. And the absense of the softc parameter is used
as a mark to distinguish reinit and probe, which is quite ugly. At the
same time the softc parameter is needed to call set_trackpoint_parameters().
o Change the arguments of probefunc_t to always supply the softc, and
use additional enum argument to tell probing from initing.
o Don't call set_trackpoint_parameters() from global doinitialize(),
instead call it from the enable_trackpoint() only.
o In enable_synaptics() call enable_trackpoint() in both probe and
reinit cases.

Several improvements to the Synaptics driver to support
semi-multitouch trackpads and some other fixes:
- Two finger scrolling support for "semi-MT" touchpads. Those include
many of the older Synaptics touchpads before "true" multitouch support
(indicated by capMultiFinger). Semi-MT touchpads can report a second
finger position, but the X or Y coordinate may be swapped with some
coordinate of the first finger. This is a result of how the hardware
works internally. Therefore, all that can be reliably extracted is the
bounding box of the two finger positions. Semi-MT touchpads can be
recognized by the capAdvancedGestures capability bit. After setting the
mode byte, advanced gestures mode has to be enabled. Then, data packets
compatible with the capMultiFinger format are sent, so the same two
finger scrolling code can be leveraged. Enabling advanced gestures mode
on true multitouch touchpads should be harmless. Linux seems to always
enable advanced gestures mode.
- Put mode setting logic into own functions synaptics_preferred_mode()
and synaptics_set_mode() to have this in one place.
synaptics_passthrough_on() and synaptics_passthrough_off() currently
always use 0xc1 as the mode byte, which may be wrong for touchpads that
don't have capExtended.
- Expose X and Y resolution of touchpad to userland. Also expose minimum
and maximum X and Y coordinates. This is useful for programs in
userspace that read raw PSM packets (with PSM_LEVEL_NATIVE enabled) and
need to interpret the coordinates.
- Also send "extended w mode" packets (see section 3.2.9 of
511-000275-01_RevB.pdf) to userspace if PSM_LEVEL_NATIVE is enabled.
This is useful for userspace programs/drivers such as
xf86-input-synaptics that can handle these packets.
- Fix parsing of nExtendedQueries, and request extended/continued
capability bits depending on this value.
- capReportsMax, capClearPad, capAdvancedGestures and capCoveredPad must
be extracted from status[0] and not status[2], I think.

Enable two finger scrolling by default and disable the edge scrolling if
the touchpad has no physical zone for it. Disable directional scrolling
by default to avoid using extended buttons as scroll buttons.
Add support for ClickPad. On Lenovo laptops, this is the button
reported when one presses the touchpad.
While there, fix a problem where the extended buttons were not reporting
the button release event correctly: we need to save the state of the
buttons and report it to sysmouse until we receive a packet from the
touchpad indicating the button has been released. This makes it
possible to use an extended button to resize a window. On Lenovo
laptops, the major buttons are actually reported as extended buttons.

The SYSCTL_NODE macro defines a list that stores all child-elements of

Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls
to support wide characters. I created a patch to add ABI compatibility
for the old calls, but I didn't get any feedback to that.
It seems now people are upgrading from 8 to 9 they experience this
issue, so add it anyway.
points are fixed addresses and (U)EFI CSM specification also mandated that.
Unfortunately, (U)EFI CSM specification does not specifically mention this
is to call service routine via interrupt vector table or to jump directly
to the entry point. As a result, some CSM seems to install two routines
and acts differently, depending on how it was executed, unfortunately.
When INT 15h is used, it calls a function pointer (which is probably a UEFI
service function). When it jumps directly to the entry point, it executes
a simple and traditional INT 15h service routine. Therefore, actually there
are two possible fixes, i. e., this fix or jumping directly to the fixed
entry point. However, we chose this fix because a) keyboard typematic
support via BIOS is becoming extremely rarer and b) we cannot support random
service routine installed by a firmware or a boot loader. This should fix
