Following u-boot commands allow FreeBSD boot on
Yiyate Android TV Box (aml8726-m3):
tv open 480p
mmc rescan 0
fatload mmc 0 0x80100000 kernel.bin
go 0x80100000
The current FreeBSD driver doesn't program the video
clocks so the u-boot tv command is necessary in order
for the frame buffer to be useful (otherwise it can
be skipped).
The SD card for the Yiyate Android TV Box doesn't need
anything special beyond creating a FAT16 and a UFS
filesystem.

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.

In smp_rendezvous_cpus we expect to wait for all cpus to enter
smp_rendezvous_action. If we call this holding a proc lock swapper may
attempt to also lock it, however as interrupts are disabled the cpu never
handles the ipi. Because smp_rendezvous_action waits for all signaled
cpus before contining it may get caught waiting for the cpu running swapper
as the proc mutex will be unlocked after smp_rendezvous_cpus finishes.
The fix is to enable interrupts in the configure stage as we should be
doing.

so that it would not return less data than requested.
Since returning less directory data than requested is not a problem
for FreeBSD and even UFS no longer returns directory structures
with d_fileno == 0, this patch stops the client from doing this.
Although entries with d_fileno == 0 should not be a problem,
the man pages no longer document that these entries should be
ignored, so there was a concern that these entries might be an
issue in the future.

It will generate many TCP packets with RST flag set.
May be RST flag should be set in the last segment only, but it could be
