parisc: kernel: using strlcpy() instead of strcpy()
'boot_args' is an input args, and 'boot_command_line' has a fix length. So use strlcpy() instead of strcpy() to avoid memory overflow. Signed-off-by: Chen Gang <gang.chen@asianux.com> Acked-by: Kyle McMartin <kyle@mcmartin.ca> Signed-off-by: Helge Deller <deller@gmx.de>
