From 5e7b6ed8e9bf3c8e3bb579fd0aec64f6526f8c81 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 20 Jun 2012 12:52:58 -0700 Subject: xtensa: replace xtensa-specific _f{data,text} by _s{data,text} commit a2d063ac216c161 ("extable, core_kernel_data(): Make sure all archs define _sdata") missed xtensa. Xtensa does have a start of data marker, but calls it _fdata, causing kernel/built-in.o:(.text+0x964): undefined reference to `_sdata' _stext was already defined, but it was duplicated by _fdata.
