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.
