Hi, I'm working on hotplug support. It looks like currently only mach-realview supports this on ARM, and it does not fully power down the core. The core just goes into wfi. If we fully power down the core being hot-removed, we need to rerun the processor init, enable mmu, turn on mmu, etc when it is brought back up.
This code is currently all put in the .init section. Changing things so that the code required for bringing up secondary cores is still present after init looks to be a fairly big change. As such I wanted to see if anyone had thoughts here before I start hacking up head.S, the linker script, etc. thanks, Steve -- Employee of Qualcomm Innovation Center, Inc.
