I've refreshed on top of libata/for-3.11 and applied it. If I broke something, please let me know.
Thanks a lot! >From b29900e62598cecd519c9ab2b8e4d03f8ebf702d Mon Sep 17 00:00:00 2001 From: Alexander Gordeev <[email protected]> Date: Wed, 22 May 2013 08:53:48 +0900 Currently all interrupts assigned to AHCI ports show up in '/proc/interrupts' as 'ahci'. This fix adds port numbers as suffixes and hence makes the descriptions distinct.
