+ ***   This header was automatically generated from a Linux kernel header

+ ***   contains no copyrightable information.
+ ***
+ ***   To edit the content of this header, modify the corresponding
+ ***   source file (e.g. under external/kernel-headers/original/) then

+ ***
+ ***   Any manual change here will be lost the next time this script will
+ ***   be run. You've been warned!
