[PATCH 3/7] alpha: Put allocated ELF notes in read-only data segment

From: Roland McGrath
Date: Wed Jul 11 2007 - 15:00:50 EST



This changes the alpha 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.
