The carambola2 exposes all the gpio pins, but some are reserved for
core functions (eg usb, ethernet, etc.) Others are configured by default
to be available as normal GPIO pins to do interesting things with.
GPIO 18->23 is the I2S, SLIC and SPDIF device pins, but none of those
are currently used. So, just allow those to show up.
Tested:
* AR9344, Carambola 2
* (.. bitbang SPI to an Adafruit LCD via libgpio, because FreeBSD could
do with more shiny output devices that aren't network interfaces.)
TODO:
There are some other pins aren't currently included here, but should be.
The LED pins are for the internal switch inside the AR9344.
* GPIO 0+1 are "LED0 + LED1", but they're tied to high for bootstrapping.
* GPIO 13-17 are "LED2..7", but they're tied (H, L, L, L, H) for bootstrapping.
* GPIO 11 and 12 are UART RTS/CTS or I2S; but GPIO 12 is tied L for bootstrap.
Check whether the page being requested is either resident or on swap. If
not, read from the zero_region instead of instantiating an unnecessary page.
This avoids consuming memory for sparse files on tmpfs, when they are read
by applications that do not use SEEK_HOLE/SEEK_DATA (which is most of them).

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.

This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.
This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

interface index is specified as zero, the system should select the
interface to use for outgoing multicast packets. Even the comment
for the in6p_set_multicast_if() function says about index of zero.
But in fact for zero index the function just returns EADDRNOTAVAIL.
I.e. if you first set some interface and then will try reset it
with zero ifindex, you will get EADDRNOTAVAIL.
Reset im6o_multicast_ifp to NULL when interface index specified as
zero. Also return EINVAL in case when ifnet_byindex() returns NULL.
This will be the same behaviour as when ifindex is bigger than
V_if_index. And return EADDRNOTAVAIL only when interface is not
multicast capable.

For VREG vnodes, return the resident page count (multiplied by PAGE_SIZE)
for the tmpfs node's anonymous VM object that stores actual file contents.
For all other vnodes, return the tmpfs_node's tn_size, which should not
be rounded to a page.
This change allows using stat(2) to identify a sparse file on tmpfs.

Previously we used pmap_kremove(), but with ARM_NEW_PMAP it does the remove
in a way that isn't SMP-coherent (which is appropriate in some circumstances
such as mapping/unmapping sf buffers). With matching enter/remove routines
for device mappings, each low-level implementation can do the right thing.

of allocations in V_nipq is racy. To fix that, we would simply stop doing
book-keeping ourselves, and rely on UMA doing that. There could be a
slight overcommit due to caches, but that isn't a big deal.
o V_nipq and V_maxnipq go away.
o net.inet.ip.fragpackets is now just SYSCTL_UMA_CUR()
o net.inet.ip.maxfragpackets could have been just SYSCTL_UMA_MAX(), but
historically it has special semantics about values of 0 and -1, so
provide sysctl_maxfragpackets() to handle these special cases.
o If zone limit lowers either due to net.inet.ip.maxfragpackets or due to
kern.ipc.nmbclusters, then new function ipq_drain_tomax() goes over
buckets and frees the oldest packets until we are in the limit.
The code that (incorrectly) did that in ip_slowtimo() is removed.
o ip_reass() doesn't check any limits and calls uma_zalloc(M_NOWAIT).
If it fails, a new function ipq_reuse() is called. This function will
find the oldest packet in the currently locked bucket, and if there is
none, it will search in other buckets until success.

It is acceptable that the size can be equal to MCLBYTES. In the later
KAME's code this check has been moved under DIAGNOSTIC ifdef, because
the size of NA and NS is much smaller than MCLBYTES. So, it is safe to
replace the check with KASSERT.
