This patch adds the MPC5121 to the list of supported devices,
enhances the doc of the clock-frequency property and removes
the obsolete cell-index property from the example nodes.
Furthermore and example for the MPC5121 has been added.

This patch series adds support for the MPC512x from Freescale to the
i2c-mpc driver. At that occasion, issues with __devinit[data] have
been fixed and the doc of the FSL I2C dts bindings updated. It has
been tested on a MPC5121ADS, TQM5200 and TQM8560 board

From: Wolfgang Grandegger w...@denx.de
The setclock initialization functions have been renamed to setup
because I2C interrupts must be enabled for the MPC512x. This requires
to handle fsl,preserve-clocking in a slighly different way. Also,
the old settings are now reported calling dev_dbg(). For
From: Wolfgang Grandegger w...@denx.de
__devinit[data] has not yet been used for all initialization functions
and data. To avoid truncating lines, the struct mpc_i2c_match_data has
been renamed to mpc_i2c_data, which is even the better name.

Hi all:
I have reserved top 128MBytes sdram for PCI DMA usage. External PCI
master sends data to top sdram and then wake up user space app.
User space use /dev/mem and mmap to access this region and then send
them to network using socket.
I found send speed of memory data in /dev/mem to network

The new Power7 processor has 4 way SMT. This 4 way SMT benefits from
dynamic power updates that arch_scale_smt_power was designed to provide.
The first patch fixes a generic scheduler bug necessary for arch_scale_smt
to properly function. The second patch implements arch_scale_smt_power

On Power7 processors running in SMT4 mode with 2, 3, or 4 idle threads
there is performance benefit to idling the higher numbered threads in
the core.

thread power in these idle cases in order to prefer threads 0,1 over
On 64-bit kernels we currently have a 512 byte struct paca_struct for
each cpu (usually just called the paca). Currently they are statically
allocated, which means a kernel built for a large number of cpus will
waste a lot of space if it's booted on a machine with few cpus.
We can avoid that by

I've tested it with manually offlined threads and it behaves as I'd like
it to.
Which is ? IE. I'm happy that you like how it behaves, but I'd like to u
understand how that is so I can make sure I'm also happy with it :-)
Cheers,
Ben.
