Subject: [PATCH 4.9 36/50] elfcore: correct reference to CONFIG_UML
Date: Mon, 25 Oct 2021 21:14:23 +0200	[thread overview]
Message-ID: <20211025190939.446228216@linuxfoundation.org> (raw)
In-Reply-To: <20211025190932.542632625@linuxfoundation.org>

From: Lukas Bulwahn <lukas.bulwahn@gmail.com>

commit b0e901280d9860a0a35055f220e8e457f300f40a upstream.

Commit 6e7b64b9dd6d ("elfcore: fix building with clang") introduces
special handling for two architectures, ia64 and User Mode Linux.
However, the wrong name, i.e., CONFIG_UM, for the intended Kconfig
symbol for User-Mode Linux was used.

Although the directory for User Mode Linux is ./arch/um; the Kconfig
symbol for this architecture is called CONFIG_UML.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

  UM
  Referencing files: include/linux/elfcore.h
  Similar symbols: UML, NUMA

Correct the name of the config to the intended one.

[akpm@linux-foundation.org: fix um/x86_64, per Catalin]
