From 8039de10aae3cd4cf0ef0ccebd58aff0e8810df2 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 10 Jan 2006 20:35:03 -0500 Subject: [PARISC] Add __read_mostly section for parisc Flag a whole bunch of things as __read_mostly on parisc. Also flag a few branches as unlikely() and cleanup a bit of code.
