Subject: [PATCH] powerpc: Add missing include <asm/stacktrace.h>

In commit 88b0fe175735 ("powerpc: Add show_user_instructions()") the
function show_user_instructions was added.

This commit adds an include of header file <asm/stacktrace.h> to provide
the missing function prototype. Silence the following gcc warning
(treated as error with W=1):

  arch/powerpc/kernel/process.c:1302:6: error: no previous prototype for ‘show_user_instructions’ [-Werror=missing-prototypes]
