Here are more patches in the progression towards multiplatform, sparse irq conversions in particular. Tegra has a handful of cleanups and general groundwork, but is not quite there yet on full enablement. Platforms that are enabled through this branch are VT8500 and Zynq. note that i.MX was converted in one of the earlier cleanup branches as well (before we started a separate topic for multiplatform). And both new platforms for this merge window, sunxi and bcm, were merged with multiplatform support enabled. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQySb/AAoJEIwa5zzehBx3Wo4P/0GrpUhB/qwuhgy43MA2I1Dv tnyuFvsfW9uRExcw2IwT39GFls98QUM9TwQxPqOTHVf+u0LkYMZ9aDeWJOdj3RvG H70Ypj4gZDrzZAFr2TUf8NnYGHd6G2EcMn3261Hjfd7YrswCjsMPvgRns7VOyHCa deif3KcLu3+HzxvuzqlVlTuSAagCQbfqqnTQduMRdJPHT3X3sXwl7ABW+qfOoeYC rjqIbjdh5dB1d/f7igtgBbXjSTnVz/Mr1+wk4rp9Xr1Wv0IXvIaSKjK2Df8ZuNAk aQ6mMy/oDVxlDSrYv0F7lB40/rsZcPqz8+fgYJ2FnvCpIM7z7NeTWD2kQJ2UaQ/s VunShloRxF8It6104EVWZDfEA9NvVBcCALSze0NukqiHZRZYGUzxRNQDrncaksC9 Lm+Z16cUWogsZq7VDCgXYQJeakPQfBDnsx7siMvAbOgvtpSClxuwhdC/czJiix7h BcpA+l5xSviUhHvzHhDt9iJxHjbUmo1xLDvaZSgj2OjAj257JcwaNBCk5BjZTCwe xZmQu1FjwaGtjLiG6QY0WJRsq1hiFRIb/MaWar/WpfqADFqARoambGFUjOl+P4Mu DIM5Z0AS04H+pLuP1QOz/yXxOPEP6Ri36to6XrgzfL/XGet5LW2P59xXxhcWC/OL /3IAcQrsAqh4aGMOstW1 =UJlh -----END PGP SIGNATURE----- Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform conversion patches from Olof Johansson: "Here are more patches in the progression towards multiplatform, sparse irq conversions in particular.

Hardware Random Number Generator Core infrastructure.

To compile this driver as a module, choose M here: the

module will be called rng-core. This provides a device
|
|
that's usually called /dev/hw_random, and which exposes one
|
|
of possibly several hardware random number generators.
|
|
|
|
These hardware random number generators do not feed directly
|
|
into the kernel's random number generator. That is usually
|
|
handled by the "rngd" daemon. Documentation/hw_random.txt

has more information.

tristate "Hardware random number generator"
|

help
|
|
This option enables UML's "hardware" random number generator. It
|
|
attaches itself to the host's /dev/random, supplying as much entropy
|
|
as the host has, rather than the small amount the UML gets from its
|
|
own drivers. It registers itself as a standard hardware random number
|
|
generator, major 10, minor 183, and the canonical device name is
|
|
/dev/hwrng.
|
|
The way to make use of this is to install the rng-tools package
|
|
(check your distro, or download from
|
|
http://sourceforge.net/projects/gkernel/). rngd periodically reads
|
|
/dev/hwrng and injects the entropy into /dev/random.
