From 98a97e6fe9eb20e877a82d0149ce6d8f832c8975 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 18 Sep 2015 13:58:35 -0500 Subject: PCI: designware: Make get_msi_addr() return phys_addr_t, not u32 Make get_msi_addr() return phys_addr_t, not u32. This allows the MSI target address to be above 4GB for 64bit or PAE systems. No functional change for the current 32bit platform users as phys_addr_t maps to u32 for them.
