Re: Where does the linux kernel put local variables

Hi, Dave

If you look at the linker script file for the kernel http://lxr.free-electrons.com/source/arch/arm/kernel/vmlinux.lds.S#L244 , you'll see that INIT_TASK_DATA (which includes the kernel stack) is between _data and _edata. This is the stack used for kernel booting and then taken over by the init task.

Thanks for your advice ,after read http://lxr.free-electrons.com/source/arch/arm/kernel/head-common.S#L122, I'v got my answer. -- Rock Lee
