RFC PATCH 1/1 openrisc: Make THREAD_SIZE available to vmlinux.lds

Make THREAD_SIZE available to vmlinux.lds on openrisc by including asm/thread_info.h the linker script.

This allows init_stack to be allocated in the linker script in a subsequent patch.

Make THREAD_SIZE available to vmlinux.lds on openrisc by including asm/thread_info.h the linker script.

This allows init_stack to be allocated in the linker script in a subsequent patch.

This looks fine, I see your patch "7e7a20a2058dc8a5106593692cfb0876de028892" (Construct init thread stack in the linker script rather than by union) already has some updates for openrisc, which are good cleanups too.

Since the two patches depend on eachother do you want to put this in the queue with your other patches?

That's my intention, yes.
