    KVM: PPC: Book3S: Fix size of the PSPB register · f35f3a48
    Thomas Huth authored
    The size of the Problem State Priority Boost Register is only
    32 bits, but the kvm_vcpu_arch->pspb variable is declared as
    "ulong", ie. 64-bit. However, the assembler code accesses this
    variable with 32-bit accesses, and the KVM_REG_PPC_PSPB macro
    is defined with SIZE_U32, too, so that the current code is
    broken on big endian hosts: kvmppc_get_one_reg_hv() will only
    return zero for this register since it is using the wrong half
    of the pspb variable. Let's fix this problem by adjusting the
    size of the pspb field in the kvm_vcpu_arch structure.
