Subject: Re: [PATCH] bcm/CmHost.c: Fix noisy compile warnings

Or we could fix it but add a multi-line comment with lots of capital
letters and exclamation marks.  I guess we would need to make a function
since this cast is in several places.

void *silence_buggy_casting(u32 pointer)
{
	/*
	 * DANGER! DANGER! DANGER! DANGER! DANGER! DANGER! DANGER!
	 * FIXME!!!  We know this cast is totally buggy.  The BCM driver
	 * doesn't work on 64 bits.  But no one knows how to make this
	 * work.  Oh well.  Let's silence the GCC warning.
	 * DANGER! DANGER! DANGER! DANGER! DANGER! DANGER! DANGER!
	 *
	 */
	return (void *)(long)pointer;
}

Something really ugly and gnarly like that would be hard to ignore.

regards,
dan carpenter
