livepatch/module: print notice of TAINT_LIVEPATCH

joe-lawrence · Jessica Yu · commit 7598d167df99 · 2017-01-30T17:07:32.000-08:00
Add back the "tainting kernel with TAINT_LIVEPATCH" kernel log message that commit 2992ef2 ("livepatch/module: make TAINT_LIVEPATCH module-specific") dropped. Now that it's a module-specific taint flag, include the module name.
