4.19-stable review patch. If anyone has any objections, please let me know.

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.
