If you want us to apply patches for us we can do that, but if you prefer to run a tree and do pull requests then you should have an URL to it here. -Olof

It would be nice to split that out into a separate change, possibly together with the trivial board.c and smp.c changes. Arnd

That’s not 100% true, the hotplug.c code implemented msm_cpu_die, which moved into smp.c I can split out scm*/smp* into a patch to enable smp if that is really desired, but not exactly sure what it gets us. - k

Yeah, sorry for not reviewiing sooner. > Hmm, how to handle this now, can we do this as a 3.16 cleanup? Yes, we've already merged it, so doing it as a cleanup should be fine. Thanks, Kevin

Introduce a new mach-qcom that will support SoCs that intend to be multiplatform compatiable while keeping mach-msm to legacy SoC/board support that will not transition over to multiplatform. As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over to mach-qcom.
