Code of Conduct: Change the contact email address

2018-10-22T06:33:36+00:00

The contact point for the kernel's Code of Conduct should now be the
Code of Conduct Committee, not the full TAB.  Change the email address
in the file to properly reflect this.

Code of Conduct Interpretation: Put in the proper URL for the committee

2018-10-22T06:33:36+00:00

There was a blank  reference for how to find the Code of Conduct
Committee.  Fix that up by pointing it to the correct kernel.org website
page location.

We use the term "TAB" before defining it later in the document.  Fix
that up by defining it at the first location.

Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted

2018-10-22T06:33:35+00:00

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community.  Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it.  We also do not expect this interpretation
to be static over time, and will adjust it as needed.

This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

Code of conduct: Fix wording around maintainers enforcing the code of conduct

2018-10-22T06:33:35+00:00

As it was originally worded, this paragraph requires maintainers to
enforce the code of conduct, or face potential repercussions.  It sends
the wrong message, when really we just want maintainers to be part of
the solution and not violate the code of conduct themselves.

Removing it doesn't limit our ability to enforce the code of conduct,
and we can still encourage maintainers to help maintain high standards
for the level of discourse in their subsystem.

Code of Conduct: Let's revamp it.

2018-09-16T18:42:28+00:00

The Code of Conflict is not achieving its implicit goal of fostering
civility and the spirit of 'be excellent to each other'.  Explicit
guidelines have demonstrated success in other projects and other areas
of the kernel.

Here is a Code of Conduct statement for the wider kernel.  It is based
on the Contributor Covenant as described at www.contributor-covenant.org

From this point forward, we should abide by these rules in order to help
make the kernel community a welcoming environment to participate in.

kconfig: do not require pkg-config on make {menu,n}config

2018-09-02T17:13:48+00:00

Meelis Roos reported a {menu,n}config regression:
 "I have libncurses devel package installed in the default system
  location (as do 99%+ on actual developers probably) and in this
  case, pkg-config is useless.  pkg-config is needed only when
  libraries and headers are installed in non-default locations but
  it is bad to require installation of pkg-config on all the machines
  where make menuconfig would be possibly run."

For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.

Raise the minimum required gcc version to 4.6

2018-08-20T21:12:38+00:00

Various architectures fail to build properly with older versions of the
gcc compiler.

An example from Guenter Roeck in thread [1]:
>
>   In file included from ./include/linux/mm.h:17:0,
>                    from ./include/linux/pid_namespace.h:7,
>                    from ./include/linux/ptrace.h:10,
>                    from arch/openrisc/kernel/asm-offsets.c:32:
>   ./include/linux/mm_types.h:497:16: error: flexible array member in otherwise empty struct
>
> This is just an example with gcc 4.5.1 for or32. I have seen the problem
> with gcc 4.4 (for unicore32) as well.

So update the minimum required version of gcc to 4.6.

Miscellanea:

 - Update Documentation/process/changes.rst

 - Remove and consolidate version test blocks in compiler-gcc.h for
   versions lower than 4.6
