arm64: move on_thread_stack() to <asm/stacktrace.h>
Currently on_thread_stack() is defined in <asm/processor.h>, depending
upon definitiong from <asm/stacktrace.h> despite this header not being
included. This ends up being fragile, and any user of on_thread_stack()
must include both <asm/processor.h> and <asm/stacktrace.h>.
We organised things this way due to header dependencies back in commit:
0b3e336601b82c6a ("arm64: Add support for STACKLEAK gcc plugin")
... but now that we no longer use current_top_of_stack(), and given that
stackleak includes <asm/stacktrace.h> via <linux/stackleak.h>, we no
longer need the definition to live in <asm/processor.h>.
Move on_thread_stack() to <asm/stacktrace.h>, where all its dependencies
are guaranteed to be defined. This requires having arm64's irq.c
explicitly include <asm/stacktrace.h>, and I've taken the opportunity to
sort the includes, which were slightly out of order.
There should be no functional change as a result of this patch.
