Subject: [PATCH] cpu_map: Add more -noTSX x86 CPU models

One of the mitigation methods for TAA[1] is to disable TSX
a41c76
support on the host system.  Linux added a mechanism to disable
a41c76
TSX globally through the kernel command line, and many Linux
a41c76
distributions now default to tsx=off.  This makes existing CPU
a41c76
models that have HLE and RTM enabled not usable anymore.
a41c76
a41c76
Add new versions of all CPU models that have the HLE and RTM
a41c76
features enabled, that can be used when TSX is disabled in the
a41c76
host system.
a41c76
a41c76
On systems disabling the features without those types defined
a41c76
in cpu-maps users end up without modern CPU types in the list
a41c76
of usable CPUs to use in the likes of virsh domcapabilities
a41c76
or tools higher in the stack like virt-manager.
a41c76

This adds:
a41c76
-Cascadelake-Server-noTSX
a41c76
-Icelake-Client-noTSX
a41c76
-Icelake-Server-noTSX
a41c76
-Skylake-Server-noTSX-IBRS
a41c76
-Skylake-Client-noTSX-IBRS
a41c76

Introduced in QEMU by commit v4.2.0-rc2-3-g9ab2237f19 (function)
a41c76
                  and commit v4.2.0-rc2-4-g02fa60d101 (names)
