spapr-rtas: fix h_rtas parameters reading
On the real hardware, RTAS is called in real mode and therefore top 4 bits of the address passed in the call are ignored. So does the patch. This converts h_rtas() to use existing rtas_ld() handlers. This fixed rtas_ld()/rtas_st() to ignore top 4 bits. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
