Both the Android and Ubuntu have QA tests which expect to be able to validate device-tree booting by looking in /proc/device-tree, so we should enable this for all Linaro builds. At the same time we can remove this option from ubuntu.conf as it's not an Ubuntu specific requirement. Signed-off-by:

[PATCH] bootwrapper: CPU hotplug aware boot protocol

To enable CPU hotplug the need to provide some boot code at the reset vector and which survives after the kernel has booted without being overwritten. We achieve this by the getting the linker script to place the code in boot.S at address zero. This now means we can delete the code that relocates t

When the generic ftrace implementation modifies code for trace-points it uses stop_machine() to call ftrace_modify_all_code() on one CPU. This ultimately calls the ARM specific function ftrace_modify_code() which updates the instruction and then does flush_icache_range(). As this cache flushing onl
