Having WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS every four lines made the headers harder to read, made the diffs much worse each time we upgraded, and wasn't really providing any benefit. Before the next uapi update, let's just stop doing this. Bug: N/A Test: builds, manually inspected files look right Change-Id: Id7088cf750894c9d24950f3d53587fe3156c4f7d

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

*** call into the kernel available to libc. It contains only constants,

*** structures, and macros generated from the original header, and thus,
|
|
*** contains no copyrightable information.
|
|
***
|
|
*** To edit the content of this header, modify the corresponding
|
|
*** source file (e.g. under external/kernel-headers/original/) then
|
|
*** run bionic/libc/kernel/tools/update_all.py

|
|
*** Any manual change here will be lost the next time this script will
|
