    KVM: s390: Allow stfle instruction in the guest · ef50f7ac
    Christian Borntraeger authored
    2.6.31-rc introduced an architecture level set checker based on facility
    bits. e.g. if the kernel is compiled to run only on z9, several facility
    bits are checked very early and the kernel refuses to boot if a z9 specific
    facility is missing.
    Until now kvm on s390 did not implement the store facility extended (STFLE)
    instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not
    boot in kvm. This patch implements stfle.
    
    This patch should go in before 2.6.31.
