The last hunk from the commit dae50295 (ipv4/ipv6 compat: Fix SSM
applications on 64bit kernels.) escaped from the compat_ipv6_setsockopt
to the ipv6_getsockopt (I guess due to patch smartness wrt searching
for context) thus breaking 32-bit and 64-bit-without-compat compilation.

Pavel,
Definitely should be in compat_ipv6_getsockopt() as the original was-- I 
hope
your patch doesn't do the same thing when applied!

Good catch!
