Subject: [PATCH 3/3] target-i386: cpu: add new CPU models for indirect branch
predictor restrictions
RH-Author: Eduardo Habkost <ehabkost@redhat.com>

O-Subject: [CONFIDENTIAL][RHEL-7.5 qemu-kvm-rhev PATCH v2 3/3] target-i386: cpu: add
new CPU models for indirect branch predictor restrictions
Bugzilla: CVE-2017-5715
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
To ensure the New CPU models won't introduce any unexpected
changes except for the spec-ctrl feature (even if people are
running older machine-types), copy all compat_props entries for
existing CPU models to their *-IBRS versions.
The only entries that are not being copied are the ones touching
"(min-)level" and "(min-)xlevel" because it's an expected result
of the CPU model change (otherwise the spec-ctrl feature would
remain unavailable to the guest).
The entries that had to be copied can be found using:
$ git grep -E 'Nehalem|Westmere|SandyBridge|IvyBridge|Haswell-noTSX|Haswell|Broadwell-noTSX|Broadwell|Skylake-Client|Skylake-Server|EPYC'
Note that the upstream-only PC_COMPAT_* macros are not being
touched as they are not used by the RHEL machine-types
