| Bugzilla: 918907 |
| Upstream status: commit 56383703c060777fd01aaf8d63d5f46d660e9fb9 |
| |
| commit 41cb383f42d0cb51d8e3e25e3ecebc954dd4196f made a guest-visible |
| change by adding the PCLMULQDQ bit to Westmere without adding |
| compatibility code to keep the ABI for older machine-types. |
| |
| Add the corresponding compat code to the rhel6.x machine-types (like it |
| was done on upstream commit 56383703c060777fd01aaf8d63d5f46d660e9fb9 for |
| pc-1.4). |
