With module addresses supported, override bpf_jit_supports_kfunc_call()
to enable kfunc support. Module address offsets can be more than 32-bit
long, so override bpf_jit_supports_far_kfunc_call() to enable 64-bit
pointers.
What's the impact on PPC32 ? There are no 64-bit pointers on PPC32.
Yeah. Not required to return true for PPC32 case and probably not a
good thing to claim support for far kfunc calls for PPC32. Changing to:
+bool bpf_jit_supports_far_kfunc_call(void)
+{
+ return IS_ENABLED(CONFIG_PPC64);
+}
