15d3fef0da03a8548fd25ec75381e86eea5c6882 24-Feb-2017 Christopher Ferris <cferris@google.com> Refactor the kernel update scripts.

The previous versions of the scripts did a lot of redundant changes
and were hard to follow.

I rewrote most of update_all.py so that it's clear about what's going on.

I updated clean_header.py to change the cleanupFile function so that
there is no magic about where the destination file is going to wind up.
Now the caller specifies the final location.

I updated utils.py so that if you are trying to do an update in one
location, but your lunch target is from another location, it causes
an error.

Bug: 35726570

Change-Id: Ic5a44d90c2774a627eecde34c0c403bc925a497c
Test: Ran the updater and verified it works properly.
Test: Verified that doing an update in one tree to another tree
Test: fails.
d12c332018143e731337292910b03fa0f41b2ca2 15-Sep-2015 Christopher Ferris <cferris@google.com> Add support for manually modified kernel headers.

This changes the scripts so that if some kernel files exists
in external/kernel-headers/modified, that they will be preferred
over the same files found in original. This is to support the case
where the kernel headers cannot be taken without some small modifications.

Included with this change, is a general cleanup of the python scripts.

This also modifies the generate uapi headers script to indicate if the
source of the modified headers has changed.

18bc975bfe41a0ef8d2df1a188078b0741dc6c25 17-Jun-2013 Elliott Hughes <enh@google.com> Slight script cleanup; make gensyscalls work from any directory.

Also remove a ton of dead code.

c95eb57405d3d2f0e6cfab313aa74b1bad280452 30-Jan-2013 Elliott Hughes <enh@google.com> Clean up trailing whitespace in the kernel headers.

And fix the scripts so they stop letting trailing whitespace through.

fc2693110ee8a2ba22a445ad9855fbe9e118d439 11-Oct-2010 David 'Digit' Turner <digit@google.com> libc: Update auto-gen scripts

Make the scripts use external/kernel-headers/original by default.

clean_header.py: Document -k<path>, add -d<path>
find_headers.py: Make kernel config files optional
update_all.py: Allow setting the path to kernel headers on the command-line
update_all.py: Better formatting of output on ttys
update_all.py: Automatically perform "git add/rm" on affected files.
SYSCALLS.TXT: Fix typo in __socketcall definition.
checksyscalls.py: Add support for superH architecture in the checks.
gensyscalls.py: Automatically perform "git add/rm" on affected files.
cpp.py: Fixed a bug that prevented certain type definitions to
be kept in the generated clean header (e.g.
struct ethtool_drvinfo in <linux/ethtool.h>)

All scripts will use the content of external/kernel-headers/original by default now.

The generated code removes all empty lines and trailing whitespace. This is useful
to ensure a unified output even if we change the parser again in the future.

The top-level disclaimer has been edited with update instructions to regenerate
the headers when needed.

Also, a warning is now inserted every 8th line in the final output:

/* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */

Changes under kernel/arch-arm and kernel/arch-x86 should correspond to whitespace
differences and additionnal struct definitions that were missed by the previous
parser implementation.

WARNING: If you run these script, do not submit the result to gerrit for now.
It seems there are discrepancies between the content of original headers
and those currently commited under bionic/libc/kernel/.

(This problem is the main motivation to insert the warning repeatedly).

Current list of issues:

- Missing SuperH headers (i.e. external/kernel-headers/original/asm-sh)
