[ANNOUNCE] [linux-linaro kernel] Start maintaining the list of the current topic owners in git.l.o

by Andrey Konovalov

Greetings, I've been asked to have the list of the linux-linaro and linux-linaro-core-tracking topic owners in git.l.o. I longer term this information would be a part of the manifest. For now it would be a text file in [1], the linux-linaro and linux-linaro-core-tracking branches. Dear topic owners, please check if this information is correct (attached). The current list reflects the 13.04 release state, e.g. the two Snowball related topics would be reworked for the next cycle (by myself, using Lee's assistance when needed). So feel free to make corrections, and don't worry too much if the currently listed topics would change in 13.05 (but let me know if this is the case). The topic names correspond to the ones in the manifests (see the [1]). Thanks, Andrey [1] git://git.linaro.org/kernel/linux-linaro-manifest.git

how to build arm64 kernel which can be downloaded from www.kernel.org (send for wuxiaoke)

by zhanqing Zhan(Qing)

> "FATAL: kernel too old" is clean message. > Use AT LEAST 3.7 kernel but better would be to use 3.9-rc even. I have tried 3.7 kernel and used 3.9-rc even. But i cannot built kenel correctly.Because some files such as arm64/boot/dts/vexpress-v2p-aarch64.dts,vexpress-foundation-v8.dts,vexpress-v2m-rs1.dtsi,skeleton.dtsi and arm64/configs/vexpress_defconfig.So i cannot complete building kernel above.Also i cannot use boot wrapper to generate a linux-system-foundation.axf suitable for a Foundation model. >Same way as you build older one. I have tried build arm64 kernel according to the steps of BuildArm64Kernel(https://wiki.linaro.org/HowTo/BuildArm64Kernel). But i encountered the problems above.So i need to ask for help to know how to build arm64 kernel and generate a linux-system-foundation.axf which can run on Foundation model.For exmaple i should how to write configuration files such as vexpress_defconfig,vexpress-foundation-v8.dts,vexpress-v2p-aarch64.dts and so on.
