    Linus Walleij 提交于
    This prints out the virtual memory assigned to KASan in the
    boot crawl along with other memory assignments, if and only
    if KASan is activated.
    
    Example dmesg from the Juno Development board:

    2160K rodata, 340K init, 217K bss, 373228K reserved, 16384K cma-reserved)
