Christophe Leroy a8936569a0 powerpc/bpf: Always reallocate BPF_REG_5, BPF_REG_AX and TMP_REG when possible ... BPF_REG_5, BPF_REG_AX and TMP_REG are mapped on non volatile registers because there are not enough volatile registers, but they don't need to be preserved on function calls. So when some volatile registers become available, those registers can always be reallocated regardless of whether SEEN_FUNC is set or not. Suggested-by: Naveen N.
