Documentation/changes: Raise minimum supported binutils version to 2.23

2020-04-08T15:02:00+00:00

The currently minimum-supported binutils version 2.21 has the problem of
promoting symbols which are defined outside of a section into absolute.
According to Arvind:

  binutils-2.21 and -2.22. An x86-64 defconfig will fail with
          Invalid absolute R_X86_64_32S relocation: _etext
  and after fixing that one, with
          Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve

Those two versions of binutils have a bug when it comes to handling
symbols defined outside of a section and binutils 2.23 has the proper
fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html

Therefore, up to the fixed version directly, skipping the broken ones.

Currently shipping distros already have the fixed binutils version so
there should be no breakage resulting from this.

For more details about the whole thing, see the thread in Link.

Documentation: provide IBM contacts for embargoed hardware

2020-03-26T14:10:44+00:00

Provide IBM contact for embargoed hardware issues. As POWER and Z are
different teams with different designs it makes sense to have separate
persons for the first contact.

docs: deprecated.rst: Add BUG()-family

2020-03-20T23:24:49+00:00

Linus continues to remind[1] people to stop using the BUG()-family of
functions. We should have this better documented (even if checkpatch.pl
has been warning[2] since 2015), so add more details to deprecated.rst,
as a distinct place to point people to for guidance.

docs: kernel-docs: Remove "Here is its" at the end of lines

2020-03-02T19:52:24+00:00

Before commit 9e03ea7f683e ("Documentation/kernel-docs.txt: convert it
to ReST markup"), it read:

       Description: Linux Journal Kernel Korner article. Here is its
       abstract: "..."

In Sphinx' HTML formatting, however, the "Here is its" doesn't make
sense anymore, because the "Abstract:" is clearly separated.
