Hello,
This series introduces a way to allow devices to contribute to initial
system randomness after a certain delay. Specifically, the virtio-rng
device can contribute initial randomness only after a successful
probe().
A delayed workqueue item is queued in the system queue to fetch this
Some RNG devices may not be ready to give early randomness at probe()
time, and hence lose out on the opportunity to contribute to system
randomness at boot- or device hotplug- time.
This commit schedules a delayed work item for such devices, and fetches
early randomness after a delay. Currently
This reverts commit ceb5d72a2e27e95bc9570ce259c45b35f0e23462.
This commit was added for -stable so systems with virtio-rng don't
freeze at boot-time.
With the addition of the previous commits that delay the request for
initial randomness after probe() is successful, this is no longer
needed.
hw_random core can ask for initial randomness after a slight delay after
probe() finishes, and we can contribute to system randomness at that
point. Tell the hw_random core by setting the HWRNG_DELAY_READ_AT_INIT
flag.

This is the driver for the Dialog DA9211 Multi-phase 12A DC-DC Buck
Converter regulator. It communicates via an I2C bus to the device.

This fixes the latency for the cpufreq policy to 1 million nanoseconds
that calls the function pxa_cpu_init for the member of the structure
called cpuinfo.transition_latency.

When there are to many open/close on a tty device in the same time,
there may be a warning like:
Warning: dev (ttyS0) tty->count(4) != #fd's(3) in tty_release_dev
That's because tty->count and files in tty->tty_files are not synchronized
in time.
So I add a lock to avoid this.
