   3 The build robot reports:
   4
   5    .tmp_kallsyms1.o: In function `kallsyms_relative_base':
   6 >> (.rodata+0x8a18): undefined reference to `_text'
   7
   8 This is when using 'make alldefconfig'. Adding this _text symbol to mark
   9 the start of the kernel as in other architecture fixes this.
