Subject: x86/Kconfig: Transmeta Crusoe is CPU family 5, not 6
From: Aleksander Mazur <deweloper@xxxxx>
commit f6a1892585cd19e63c4ef2334e26cd536d5b678d upstream.
The kernel built with MCRUSOE is unbootable on Transmeta Crusoe. It shows
the 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.
Remove MCRUSOE from the condition introduced in commit in Fixes, effectively
changing X86_MINIMUM_CPU_FAMILY back to 5 on that machine, which matches the
CPU family given by CPUID.
