I came across your email while searching for a solution to the above
build error.

In addition to setting CONFIG_BROKEN_RODATA=y, Jan Beulich sent a
patch [1] to LKML that also fixes this build problem for me.

[1] https://lkml.org/lkml/2012/11/23/308

It doesn't appear to have hit Linus' tree yet though, but with luck
someone will pick it up before 3.8 final.

Cheers,
Shaun
