Fix KSPLICE_IP for new x86-64 kernels.
Even though struct thread_struct.ip is present after 2.6.25 as a
result of the x86 unification, it is still not used for x86-64; the
context switching macro always begins execution at thread_return.
(See the definitions of switch_to in arch/x86/include/asm/system.h.)
This unused field was removed for 2.6.31 under !CONFIG_X86_32 by
commit 0c23590f00f85467b318ad0c20c36796a5bd4c60.
