Subject: [PATCH v6 0/5] clean up redundant 'kvm_run' parameters
Date: Tue, 23 Jun 2020 21:14:13 +0800
Message-ID: <20200623131418.31473-1-tianjia.zhang@linux.alibaba.com> (raw)

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

---
v6 changes:
  Rearrange patch sets, only keep the unmerged patch.
  rebase on mainline.

v5 change:
  ppc: fix for review.

v4 change:
  mips: fixes two errors in entry.c.

v3 change:
  Keep the existing `vcpu->run` in the function body unchanged.

v2 change:
  s390 retains the original variable name and minimizes modification.
