Hi Amir, Can you please add a new kernel parameter say, "low_memory_env" and change rest of the patches to make use of this kernel parameter and repost. I think for the drivers who were using "reset_devices" to switch to low memory profile, you will have to retain that otherwise new kernel will be broken with old kexec-tools/scripts which don't know that a new parameter "low_memory_env" needs to be passed. May be we can do following. /* TODO: Get rid of dependency on reset_devices after some time */ if (low_memory_env || reset_devices) use_low_memory_profile; Thanks Vivek -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
