    MIPS: Remove function size check in get_frame_info() · 2b424cfc
    Jun-Ru Chang authored
    Patch (b6c7a324 "MIPS: Fix get_frame_info() handling of
    microMIPS function size.") introduces additional function size
    check for microMIPS by only checking insn between ip and ip + func_size.
    However, func_size in get_frame_info() is always 0 if KALLSYMS is not
    enabled. This causes get_frame_info() to return immediately without
    calculating correct frame_size, which in turn causes "Can't analyze
    schedule() prologue" warning messages at boot time.
    
    This patch removes func_size check, and let the frame_size check run
    up to 128 insns for both MIPS and microMIPS.
