  1. kernel: Map most files to use export.h instead of module.h

    The changed files were only including linux/module.h for the
    EXPORT_SYMBOL infrastructure, and nothing else.  Revector them
    onto the isolated export header for faster compile times.
    
    Nothing to see here but a whole lot of instances of:
    
      -#include <linux/module.h>
      +#include <linux/export.h>
    
    This commit is only changing the kernel dir; next targets
    will probably be mm, fs, the arch dirs, etc.

    stack_trace: Add weak save_stack_trace_regs()

    Add weak symbol of save_stack_trace_regs() as same as
    save_stack_trace_tsk() since that is not implemented
    except x86 yet.

  1. stacktrace: provide save_stack_trace_tsk() weak alias

    Impact: build fix
    
    Some architectures have not implemented save_stack_trace_tsk() yet:
    
      fs/built-in.o: In function `proc_pid_stack':
      base.c:(.text+0x3f140): undefined reference to `save_stack_trace_tsk'
    
    So warn about that if the facility is used.

    stacktrace: print_stack_trace() cleanup

    - shorter code and better atomicity with regards to printk().
    
    (It's been tested with the backtrace self-test code on i386 and x86_64.)

    stacktrace: don't crash on invalid stack trace structs

    This patch makes the stacktrace printout code \warn when the entries
    pointer is unset rather than crashing when trying to access it in an
    attempt to make it a bit more robust.
    
    I was saving a stacktrace into an skb and forgot to copy it across skb
    copies... I have since fixed the code, but it would have been easier
    had the kernel not crashed in an interrupt.
