From 1befdd5536e1500371f7f884d0f0ae528a519333 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 14 Oct 2010 12:36:49 -0700 Subject: MIPS: Implement __read_mostly Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth.
