#     KVM: PPC: Book3S HV: Fix regression on big endian hosts
#     
#     VCPU_CR is the offset of arch.regs.ccr in kvm_vcpu.
#     arch/powerpc/include/asm/kvm_host.h defines arch.regs as a struct
#     pt_regs, and arch/powerpc/include/asm/ptrace.h defines the ccr field
#     of pt_regs as "unsigned long ccr".  Since unsigned long is 64 bits, a
#     64-bit load needs to be used to load it, unless an endianness specific
#     correction offset is added to access the desired subpart.  In this
#     case there is no reason to _not_ use a 64 bit load though.
#     
#     Fixes: 6c85b7bc637b ("powerpc/kvm: Use UV_RETURN ucall to return to ultravisor")
