From be1b3d8cb141c0705d61af2e2372d72ff16c7d04 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Thu, 18 Oct 2007 00:04:25 -0700 Subject: [PATCH] [PARISC] Beautify parisc vmlinux.lds.S Introduce a consistent layout of vmlinux. The same layout has been introduced for most architectures. And the same time move a few label definitions inside the curly brackets so they are assigned the correct starting address. Before a ld inserted alignment would have casued the label to pint before the actual start of the section.
