From 689ee8c95f399998f52eda827849b7771629a53c Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Tue, 3 May 2016 15:41:25 +1000 Subject: powerpc/powernv: Data type unsigned int for PE number This changes the data type of PE number from "int" to "unsigned int" in order to match the fact PE number is never negative: * The number of PE to which the specified PCI device is attached. * The PE number map for SRIOV VFs. * The returned PE number from pnv_ioda_alloc_pe(). * The returned PE number from pnv_ioda2_pick_m64_pe().
