3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> commit 5e7b6ed8e9bf3c8e3bb579fd0aec64f6526f8c81 upstream. 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.
