Linus Torvalds 97b1007a29 ARM: arm-soc platform updates for 3.10, part 1 
This branch contains platform updates for 3.10. Among the highlights:
 
 - Support for the new Atmel Cortex-A5 based platforms (SAMA5D3)
 - New support for CSR SiRFatlas6 SoCs
 - A handful of updates for NVidia T114 (a.k.a. Tegra 4)
 - A bunch of updates for the shmobile platforms
 - A handful of updates for davinci
 - A few updates for Qualcomm MSM
 - Plus a handful of other patches, defconfig updates, etc.
