[PATCH] relocatable kernel: Kallsyms generate relocatable symbols
Print the addresses of non-absolute symbols relative to _text so that ld will generate relocations. Allowing a relocatable kernel to relocate them. We can't actually use the symbol names because kallsyms includes static symbols that are not exported from their object files. Add the _text symbol definitions to the architectures which don't define it otherwise linker will fail. Signed-off-by: Eric W.
