Can you explain what you mean in details?
The function is:
static inline bool __must_check arch_get_random_seed_long(unsigned long *v)
{
if (ppc_md.get_random_seed)
return ppc_md.get_random_seed(v);
return false;
}
ppc_md is non-GPL:
77 /* The main machine-dep calls structure
78 */
79 struct machdep_calls ppc_md;
80 EXPORT_SYMBOL(ppc_md);
And get_random_seed is initialized in in arch/powerpc/platforms/powernv/rng.c
with different functions that are static and not exported at all.
I don't understand where arch_get_random_seed_long calls GPL...
