Subject: [PATCH v2 0/7] clean up redundant 'kvm_run' parameters
Date: Wed, 22 Apr 2020 20:58:03 +0800	[thread overview]
Message-ID: <20200422125810.34847-1-tianjia.zhang@linux.alibaba.com> (raw)

In the current kvm version, 'kvm_run' has been included in the 'kvm_vcpu'
structure. 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.
