      [S390] kvm-s390: fix stfle facilities numbers >=64 · 9950f8be
      Christian Borntraeger 提交于
      Currently KVM masks out the known good facilities only for the first
      double word, but passed the 2nd double word without filtering. This
      breaks some code on newer systems:

      So lets also mask the 2nd double word. Facilites 66,76,76,77 should be fine.

      KVM: s390: Allow stfle instruction in the guest · ef50f7ac
      Christian Borntraeger 提交于
      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.
