From 2e1d5b8f24a887caded5ae3ceb2f341d4fbd1861 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 19 Jul 2007 01:48:37 -0700 Subject: [PATCH] x86_64: Put allocated ELF notes in read-only data segment This changes the x86_64 linker script to use the asm-generic NOTES macro so that ELF note sections with SHF_ALLOC set are linked into the kernel image along with other read-only data. The PT_NOTE also points to their location. This paves the way for putting useful build-time information into ELF notes that can be found easily later in a kernel memory dump.
