Subject: [PATCH] kvm: arm64: Fix comment for KVM_PHYS_SHIFT
Date: Thu, 14 Feb 2019 01:45:46 +0000 [thread overview]
Message-ID: <1550108746-14704-1-git-send-email-yuzenghui@huawei.com> (raw)
Since Suzuki K Poulose's work on Dynamic IPA support, KVM_PHYS_SHIFT will
be used only when machine_type's bits[7:0] equal to 0 (by default). Thus
the outdated comment should be fixed.
