Make @target the new discriminator for the @CpuInfoFast return structure. Keep @arch for compatibility. Cc: "Daniel P. Berrange" Cc: Eric Blake Cc: Markus Armbruster Signed-off-by: Laszlo Ersek Reviewed-by: Eric Blake Reviewed-by: Markus Armbruster --- Notes: PATCHv3: - remove superfluous empty comment line addition after @target - pick up Eric's R-b - skip Markus's R-b due to the next patch PATCHv2: - drop patch v1 5/6 with the CpuInfoCommon refactoring / extraction, as @CpuInfo / @query-cpus are deprecated [Eric, Markus] - for the same reason, add @target to @CpuInfoFast / @query-cpus-fast only [Eric, Markus] - Can't set @arch compatibly from a QAPI enum lookup of the proposed TARGET_BASE_ARCH macro, because TARGET_BASE_ARCH=s390x is not identical to the @s390 @CpuInfoArch constant -- see more at . Keep sysemu_target_to_cpuinfo_arch() instead.
