From 72da0b07b1b497927758a2102b856ce41e4ba81e Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 15 Sep 2011 08:58:51 +0100 Subject: x86: constify PCI raw ops structures As with any other such change, the goal is to prevent inadvertent writes to these structures (assuming DEBUG_RODATA is enabled), and to separate data (possibly frequently) written to from such never getting modified.
