[PATCH 2/7] i386: Add default_version parameter to CPU version functions
Posted by Eduardo Habkost 6 years, 3 months ago
Not all CPU version lookup code will use default_cpu_version:
we'll change query-cpu-definitions to optionally get a machine
type argument.  Make CPU version resolving functions get an
explicit default_version argument.

All callers are being changed to use default_cpu_version as
argument, so no behavior is being changed yet.
