    If you try
    strings vmlinux|grep /usr

    you get a bunch of strings like:

    One other couple of Kb. The problem is not that, but the string comes from:
    ..(line 110)
    * Temporary debugging check to catch old code using
    * unmapped ISA addresses. Will be removed in 2.4.
    #if 1
    extern void *__io_virt_debug(unsigned long x, const char *file, int line);
    extern unsigned long __io_phys_debug(unsigned long x, const char *file, int li
    #define __io_virt(x) __io_virt_debug((unsigned long)(x), __FILE__, __LINE__)
    //#define __io_phys(x) __io_phys_debug((unsigned long)(x), __FILE__, __LINE__)
    #define __io_virt(x) ((void *)(x))
    //#define __io_phys(x) __pa(x)

    As you see, it was not removed in 2.4...
