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

are presented to ARM part through memory region shared between
VC and ARM.
evdev is used as userland interface. FT5406 supports up to

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
corruption, we should disable the hole_birth feature. Using a tunable

take advantage of the feature.

Suspend:
- Prevent the backend from being touched on TX path.
- Clear the RNDIS RX filter, and wait for RX to drain.
- Make sure that NVS see the chimney sending buffer and RXBUF
disconnection, before unlink these buffers from the channel.
Resume:
- Reconfigure the RNDIS filter.
- Allow TX path to work on the backend.
- Kick start the TX eof task, in case the OACTIVE is set.
This fixes various panics, when the interface has traffic and MTU

The command interpreter does leave command_errmsg as is after printing its
content, assuming the next command will reset it in bf_command(). However,
in case the forth native word is defined as builtin, the bf_command is not
used and forth words will also end up the command_errmsg content printed.
Since command_errmsg is pointer to actual error message, which can be static
read only string, we can not just set *command_errmsg = '\0', instead we need
to reset the pointer itself.

Summary:
This enables some features of the DIU, using a static configuration,
specified either via a 'edid' property on the 'display' FDT node, or a
'video-mode' environment variable (bootarg). 'video-mode' was chosen because it
matches u-boot's naming, so it can be set with:
setenv bootargs video-mode=${video-mode}
at the u-boot CLI.
Mouse cursor is not supported currently, as a hardware cursor is not supported
by framebuffer VT yet. Currently it only supports a 32bpp ARGB (actually BGRA)
format, and only a single composite plane, at up to 1280x1024.

(1) Print the default segment %ss before adresses relative to %bp.
This is too cluttered for me, but so is printing some other default
prefixes, and this is a reasonable reminder that %ss is quite
likely to be different from %ds in 16-bit mode.
db_disasm still handles prefixes poorly, by trying to discard
redundant ones. This loses information, and sometimes the result
is wrong or misleading.
Clean up nearby initializations and dead code.
(2) Fix decoding of operand and address size prefixes in 16-bit mode.
They reverse the default in all modes.

db_segsize().
Use db_segsize() to set the default operand/address size for
disassembling. Allow overriding this with the "alternate" display
format /I. The API of db_disasm() should be debooleanized to pass a
more general request (amd64 needs overrides to sizes of 16, 32, and
64, but this commit doesn't implement anything for amd64 since much
larger changes are needed to restore the amd64 disassmbler's support
for non-default sizes).
Fix db_print_loc_and_inst() to ask for the normal format and not the
alternate in normal operation.
This is most useful for vm86 mode, but also works for 16-bit protected
mode.
Use db_segsize() to avoid trying to print a garbage stack trace if %cs
is 16 bits. Print something like the stack trace termination message
for a trap boundary instead.
Document that the alternate format is now useful on i386.
early printfs and debugging of vm86 initialization and some other early
initialization in some cases.) Add an option debug.late_console (with
default 1=off) to move console and kdb initialization back where it was.
Do the same for amd64 although there is no vm86 there.
On my test system, debug.late_console=0 works for the syscons, sio and
uart console drivers on amd64 and i386, and for vt on i386 but not on
amd64.
The early printfs fixed by debug.late_console=0 are:
- on i386, the message about lost memory above 4G
- with -v in otherwise normal use, about 20 printfs for SMAP
- other debugging messages for memory sizing. Mostly under -v and
not printed in normal use.
Document in a comment how much earlier the initialization and early
printf()s can be. That is very early for the console. Not much more
than curthread is needed. kdb use obviously needs to be not so early,
since it needs IDT initialization and that is done relatively late
for convenience and historical reasons.
