    linux(4): Use Linux dev_t type for mknod syscalls dev argument
    
    As of version 2.6.0 of the Linux kernel, dev_t is a 32-bit unsigned integer
    on all platforms. Prior the 2.6 kernel dev_t type was an unsigned short.
    However, since the firs commit of the Linuxulator, mknod syscall get int dev
    argument.
    Also, there is some confusion here, while the kernel declares a dev_t type
    as a 32-bit sized, the user-space dev_t type can be size of 64 bits, e.g.,
    in the Glibc library.
    To avoid confusion and to help porting of the Linuxulator to other platforms
    use explicit l_dev_t for dev argument of mknod syscalls.
    
    (cherry picked from commit ca3333dd4a3bef7b615d5df104c525f8cac51b26)
