From 2024c39dbba4d036f0b16daf530ad5f4416fb344 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 1 Dec 2006 16:02:40 +0100 Subject: [PATCH] [ARM] 3965/1: ixp2000: fix handling of pci master aborts The master abort check in ixp2000_pci_read_config() recently started failing due to the compiler optimising out the read access following the clearing of pci_master_aborts. Mark pci_master_aborts volatile to force the compiler to reload it on every use.
