[PATCH] arm64: move elf notes into readonly segment

From: Mark Salter
Date: Fri Aug 23 2013 - 11:16:53 EST


The current vmlinux.lds.S places the notes sections between the
end of rw data and start of bss. This means that _edata doesn't
really point to the end of data. Since notes are read-only, this
patch moves them to the read-only segment so that _edata does
point to the end of initialized rw data.
