commit a2d063ac216c1618bfc2b4d40b7176adffa63511 ("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.
