Summary:
NXP/Freescale, among others, includes an optional cell-index property
on nodes to denote the SoC block number of the node. This can be useful if, for
example, a node is disabled or nonexistent in the fdt, or the blocks are not
organized in address-sorted order. For instance, on the P1022, DMA2 is located
at CCSR offset 0xC000, while DMA1 is located at 0x21000.

during testing of network related changes where cached entries may pollute your
results, or during known congestion events where you don't want to unfairly
penalize hosts.
Prior to r232346 this would have meant you would break any connection with a sub
1500 MTU, as the hostcache was authoritative. All entries as they stand today
should simply be used to pre populate values for efficiency.

Restructure code slightly to save ip_tos bits earlier. Fix the bug
where the ip_tos field is zeroed out before assigning to the iptos
variable. Restore the ip_tos and ip_ver fields only if they have
been zeroed during the pseudo-header checksum calculation.

As a side effect of r261242 when using accept_filter the
first call to soisconnected() is done earlier in tcp_input()
instead of tcp_do_segment() context. Restore the expected behaviour.
Note: This call to soisconnected() seems to be extraneous in all
cases (with or without accept_filter). Will be addressed in a
separate commit.

function from restarting the timer.
Commonly taskqueue_enqueue_timeout() is called from within the task
function itself without any checks for teardown. Then it can happen
the timer stays active after the return of taskqueue_drain_timeout(),
because the timeout and task is drained separately.
This patch factors out the teardown flag into the timeout task itself,
allowing existing code to stay as-is instead of applying a teardown
flag to each and every of the timeout task consumers.
Add assert to taskqueue_drain_timeout() which prevents parallel
execution on the same timeout task.
Update manual page documenting the return value of
taskqueue_enqueue_timeout().

Technically touchscreen chip is FT5406 but all hardware
communication is performed by VideCore and only final results
are presented to ARM part through memory region shared between
VC and ARM.
evdev is used as userland interface. FT5406 supports up to
10 touchpoints, but for now driver emulates single touch device
because I do not have GUI bits to test this functionality.
Driver is not enabled in default config for RPI and RPI2

- The original 'disengage' ATA controller model does not work properly
for all possible disk configurations. Use the newly added ATA disk
veto eventhandler to fit into all possible disk configuration.
- If the 'invalid LUN' happens on blkvsc controllers, return
CAM_DEV_NOT_THERE so that CAM will not destroy attached disks under
the blkvsc controllers.

Until we can resolve the numerous hole_birth bugs that have cropped up
recently, and come up with a way going forwards to protect users from
