Subject: [PATCH v2 16/66] KVM: x86: Encapsulate CPUID entries and metadata in struct
Date: Mon, 2 Mar 2020 15:56:19 -0800 [thread overview]
Message-ID: <20200302235709.27467-17-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200302235709.27467-1-sean.j.christopherson@intel.com>
Add a struct to hold the array of CPUID entries and its associated
metadata when handling KVM_GET_SUPPORTED_CPUID. Lookup and provide
the correct entry in do_host_cpuid(), which eliminates the majority of
array indexing shenanigans, e.g. entries[i -1], and generally makes the
code more readable. The last array indexing holdout is kvm_get_cpuid(),
which can't really be avoided without throwing the baby out with the
bathwater.
No functional change intended.
