[PATCH v3 2/4] target/i386: Remove monitor from some CPU models

2020-02-12 Thread Tao Xu
Add new version of Snowridge, Denverton, Opteron_G3, EPYC, and Dhyana CPU model to remove MONITOR/MWAIT feature. After QEMU/KVM use "-overcommit cpu-pm=on" to expose MONITOR/MWAIT (commit id 6f131f13e68d648a8e4f083c667ab1acd88ce4cd), the MONITOR/MWAIT feature in these CPU model is unused.
