 quirks


I've applied your first two patches, thanks Michael!

Regarding this patch, it does not apply cleanly to the latest 
x86 tree:

 2 out of 5 hunks FAILED -- rejects in file arch/x86/kernel/reboot.c

which you can pick up from:

 git pull git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git master

Also, a style nit, these comments:

> +	/* Write zero to CMOS register number 0x0f, which the BIOS POST
> +	   routine will recognize as telling it to do a proper reboot.  (Well
> +	   that's what this book in front of me says -- it may only apply to
> +	   the Phoenix BIOS though, it's not clear).  At the same time,
> +	   disable NMIs by setting the top bit in the CMOS address register,
> +	   as we're about to do peculiar things to the CPU.  I'm not sure if
> +	   `outb_p' is needed instead of just `outb'.  Use it to be on the
> +	   safe side.  (Yes, CMOS_WRITE does outb_p's. -  Paul G.)
> +	 */

and the other similar comments that you move should be coverted 
to the customary (multi-line) comment style:

  /*
   * Comment .....
   * ...... goes here.
   */

specified in Documentation/CodingStyle.

I realize that you only move code here - but it's worth cleaning 
it up a bit when touching it.

Thanks,

        Ingo
