| Subject: x86/microcode: Adjust late loading result reporting message |
| |
| From: Ashok Raj <ashok.raj@intel.com> |
| |
| [ Upstream commit 6eab3abac7043226e5375e9ead0c7607ced6767b ] |
| |
| During late microcode loading, the "Reload completed" message is issued |
| unconditionally, regardless of success or failure. |
| |
| Adjust the message to report the result of the update. |
