- *	Precise Delay Loops for i386

- *	Copyright (C) 1993 Linus Torvalds
- *	Copyright (C) 1997 Martin Mares <mj@atrey.karlin.mff.cuni.cz>
- *
- *	The __delay function must _NOT_ be inlined as its execution time
- *	depends wildly on alignment on many x86 processors. The additional
- *	jump magic is needed to get the timing stable on all the CPU's
- *	we have to worry about.
