x86/ldt: Initialize the context lock for init_mm The mutex mm->context->lock for init_mm is not initialized for init_mm. This wasn't a problem because it remained unused. This changed however since commit 4fc19708b165c ("x86/alternatives: Initialize temporary mm for patching") Initialize the mutex for init_mm.
