Description: Digital signature
Exynos4 has saveral PPMUs and each of them has operation clock which
can be gated through CMU's SFR control.
New clocks are listed below. All clocks are added as a gate-typed clock.
CLK_PPMULEFT, CLK_PPMURIGHT, CLK_PPMUCAMIF, CLK_PPMUTV, CLK_PPMUMFC_L,
CLK_PPMUMFC_R, CLK_G3D, CLK_PPMUIMAGE,
This is a fix for commit:
39c60a0948cc06139e2fbfe084f83cb7e7deae3b sd: fix array cache flushing bug
causing performance problems
We must notify the block layer via q-flush_flags after temporary change the
cache_type to write through.
If not, SYNCHRONIZE CACHE command will still be generated.

Hello Wolfram,
No news from you regarding this patch series.
Is there anything you want me to fix ?
Otherwise It would be great to have this series merged, because the PMIC

Subject: Regression in hyperv network driver in 3.14
Hello,
using a 3.14 kernel in a Linux VM running on
This patch adds an interface to the random pool for feeding entropy in-kernel.
It may serve as a destination for dedicated HWRNGs.
It resembles -- and could be merged with -- the ioctl(RNDADDENTROPY) code, plus
a sleep condition for eager writers.

This can be viewed as the in-kernel equivalent of hwrngd;
like FUSE it is a good thing to have a mechanism in user land,
but for some reasons (simplicity, secrecy, integrity, speed)
it may be better to have it in kernel space.
This patch creates a thread once a hwrng registers, and uses
