Subject: [PATCH] x86/Kconfig: Transmeta Crusoe is cpu family 5, not 6
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")
