Revision d28f87aa87ce8b196349d7c306a7e6fe3abd7155 authored by Tejun Heo on 05 July 2008, 04:10:50 UTC, committed by Linus Torvalds on 05 July 2008, 20:05:37 UTC
Commit ea0c62f7cf70f13a67830471b613337bd0c9a62e tried to clear all
bits in irq_stat but it didn't actually achieve that as irq_stat was
anded with port_map right after read.  This patch makes ahci driver
always use the unmasked value to clear irq_status.

While at it, add explanation on the peculiarities of ahci IRQ
clearing.

This was spotted by Linus Torvalds.
