Arnd Bergmann adb2cfd3f2 printf: fix errname.c list 
[ Upstream commit 0c2baf6509 ]

On most architectures, gcc -Wextra warns about the list of error
numbers containing both EDEADLK and EDEADLOCK:

lib/errname.c:15:67: warning: initialized field overwritten [-Woverride-init]
   15 | #define E(err) [err + BUILD_BUG_ON_ZERO(err <= 0 || err > 300)] = "-" #err
      |                                                                   ^~~
lib/errname.c:172:2: note: in expansion of macro 'E'
  172 |  E(EDEADLK), /* EDEADLOCK */
      |  ^

On parisc, a similar error happens with -ECANCELLED, which is an
alias for ECANCELED.

Make the EDEADLK printing conditional on the number being distinct
from EDEADLOCK, and remove the -ECANCELLED bit completely as it
can never be hit.

To ensure these are correct, add static_assert lines that verify
all the remaining aliases are in fact identical to the canonical
name.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
