From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>
Move processor compatibility check from kvm_arch_processor_compat() into
kvm_arch_hardware_setup(). The check does model name comparison with a
global variable, cur_cpu_spec. There is no point to check it at run time
on all processors.
kvmppc_core_check_processor_compat() checks the global variable. There are
five implementation for it as follows.
arch/powerpc/include/asm/cputable.h: extern struct cpu_spec *cur_cpu_spec;
arch/powerpc/kvm/book3s.c: return 0
arch/powerpc/kvm/e500.c: strcmp(cur_cpu_spec->cpu_name, "e500v2")
arch/powerpc/kvm/e500mc.c: strcmp(cur_cpu_spec->cpu_name, "e500mc")
strcmp(cur_cpu_spec->cpu_name, "e5500")
strcmp(cur_cpu_spec->cpu_name, "e6500")
