ruby CVS bug

[Aivils S. <Aiv...@un...>]

Hi
     Here bug to lead oops. My show up depend hardware and console count.
Without this patch I get message:
Uncompressing Linux kernel
invalid compressed format (err=2)
-- system halted

and more various oops. After patch I get normal ruby.

kmalloc not change memory content. vty_driver->termios stay undefined.
Later in init_dev() tty_io.c termios checking going to wrong way and
kernel oops.
