*	[PATCH] HZ: 300Hz support	Alan Cox	2006-12-07	1	-5/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Fix two things. Firstly the unit is "Hz" not "HZ". Secondly it is useful to have 300Hz support when doing multimedia work. 250 is fine for us in Europe but the US frame rate is 30fps (29.99 blah for pedants). 300 gives us a tick divisible by both 25 and 30, and for interlace work 50 and 60. It's also giving similar performance to 250Hz. I'd argue we should remove 250 and add 300, but that might be excess disruption for now.

*	[PATCH] i386: Selectable Frequency of the Timer Interrupt	Christoph Lameter	2005-06-23	1	-0/+46
	Make the timer frequency selectable. The timer interrupt may cause bus and memory contention in large NUMA systems since the interrupt occurs on each processor HZ times per second.
