    ARM: 9303/1: kprobes: avoid missing-declaration warnings
    
    [ Upstream commit 1b9c3ddcec6a55e15d3e38e7405e2d078db02020 ]
    
    checker_stack_use_t32strd() and kprobe_handler() can be made static since
    they are not used from other files, while coverage_start_registers()
    and __kprobes_test_case() are used from assembler code, and just need
    a declaration to avoid a warning with the global definition.
