Subject: [PATCH] x86: Improve description of IA32_EMULATION_DEFAULT_DISABLED
Date: Tue, 30 Jan 2024 10:45:43 +0100 [thread overview]
Message-ID: <20240130104543.28840812.hanno@hboeck.de> (raw)
The description of the option disables a default, but does not mention
how to change that default. To make it easier to find out, mention boot
parameter ia32_emulation.
