- * Test that the kernel properly handles PMAE across context switches.
- *
- * We test this by calling into the kernel inside our EBB handler, where PMAE
- * is clear. A cpu eater companion thread is running on the same CPU as us to
- * encourage the scheduler to switch us.
- *
- * The kernel must make sure that when it context switches us back in, it
- * honours the fact that we had PMAE clear.
- *
- * Observed to hit the failing case on the first EBB with a broken kernel.
