Merge "init.rc: disable kernel module autoloading"

    # Disable sysrq from keyboard

    write /proc/sys/kernel/sysrq 0

    # Android doesn't need kernel module autoloading, and it causes SELinux

    # denials.  So disable it by setting modprobe to the empty string.  Note: to

    # explicitly set a sysctl to an empty string, a trailing newline is needed.

    write /proc/sys/kernel/modprobe \n

    # Set the security context of /adb_keys if present.
