Earlier than historical reasons, many kvm-related function parameters retain the 'kvm_run' and 'kvm_vcpu' parameters at the same time. This patch does a unified cleanup of these remaining redundant parameters. This series of patches has completely cleaned the architecture of arm64, mips, ppc, and s390 (no such redundant code on x86). Due to the large number of modified codes, a separate patch is made for each platform. On the ppc platform, there is also a redundant structure pointer of 'kvm_run' in 'vcpu_arch', which has also been cleaned separately. --- v2 change: s390 retains the original variable name and minimizes modification.
