[PATCH 5.14 148/151] x86/entry: Correct reference to intended CONFIG_64_BIT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx>

commit 2c861f2b859385e9eaa6e464a8a7435b5a6bf564 upstream.

Commit in Fixes adds a condition with IS_ENABLED(CONFIG_64_BIT),
but the intended config item is called CONFIG_64BIT, as defined in
arch/x86/Kconfig.

Fortunately, scripts/checkkconfigsymbols.py warns:

64_BIT
Referencing files: arch/x86/include/asm/entry-common.h

Correct the reference to the intended config symbol.
