    s390/bpf,jit: fix prolog oddity · 6cef3003
    Martin Schwidefsky authored
    The prolog of functions generated by the bpf jit compiler uses an
    instruction sequence with an "ahi" instruction to create stack space
    instead of using an "aghi" instruction. Using the 32-bit "ahi" is not
    wrong as the stack we are operating on is an order-4 allocation which
    is always aligned to 16KB. But it is more consistent to use an "aghi"
    as the stack pointer is a 64-bit value.
