    KVM: PPC: Book3S HV: Basic little-endian guest support · d682916a
    Anton Blanchard authored
    We create a guest MSR from scratch when delivering exceptions in
    a few places.  Instead of extracting LPCR[ILE] and inserting it
    into MSR_LE each time, we simply create a new variable intr_msr which
    contains the entire MSR to use.  For a little-endian guest, userspace
    needs to set the ILE (interrupt little-endian) bit in the LPCR for
    each vcpu (or at least one vcpu in each virtual core).
    
    [paulus@samba.org - removed H_SET_MODE implementation from original
    version of the patch, and made kvmppc_set_lpcr update vcpu->arch.intr_msr.]
