| H A D | irq.c | 7a26d3a3 Mon Mar 03 20:57:18 CST 2008 eric miao <eric.miao@marvell.com> [ARM] pxa: generalize the muxed gpio IRQ handling code with loop and ffs()
1. As David Brownell suggests, using ffs() is going to make the loop
a bit faster (by avoiding unnecessary shift and iteration)
2. Russell suggested find_{first,next}_bit() being used with the
gedr[] array
