Subject: [PATCH] x86/Kconfig: Transmeta Crusoe is cpu family 5, not 6
Date: Tue, 23 Jan 2024 14:43:00 +0100	[thread overview]
Message-ID: <20240123134309.1117782-1-deweloper@wp.pl> (raw)
In-Reply-To: <30A7BB83-E44A-4082-B5DE-AB9FBF0AB555@zytor.com>

The kernel built with MCRUSOE is unbootable on Transmeta Crusoe.
It shows following error message:

> This kernel requires an i686 CPU, but only detected an i586 CPU.
> Unable to boot - please use a kernel appropriate for your CPU.

Fix this by removing MCRUSOE from condition introduced in 25d76ac88821,
effectively changing X86_MINIMUM_CPU_FAMILY back to 5, what matches CPU
family given by CPUID.

Tested on HP t5300.

Fixes: 25d76ac88821 ("x86/Kconfig: Explicitly enumerate i686-class CPUs in Kconfig")
