    ARM: 8179/1: kprobes-test: Fix compile error "bad immediate value for offset" · ad684dce
    Jon Medhurst authored
    When compiling kprobes-test-arm.c the following error has been observed
    
    /tmp/ccoT403o.s:21439: Error: bad immediate value for offset (4168)
    
    This is caused by the compiler spilling it's literal pool too far away
    from the site which is trying to reference it with a PC relative load.
    This arises because the compiler is underestimating the size of the
    inline assembler code present, which apparently it approximates as 4
    bytes per line or instruction.
    
    We fix this problem by moving the operations which generate more than
    4 bytes out of the text section. Specifically, moving the .ascii
    directives to the .rodata section.
