+ * per-CPU data.  Using only registers avoids having to map memory into the
+ * guest, doesn't require a valid, stable GS.base, and reduces the risk of
+ * for recursive faults when accessing memory in the handler.  The downside to
+ * using registers is that it restricts what registers can be used by the actual
+ * instruction.  But, selftests are 64-bit only, making register* pressure a
+ * minor concern.  Use r9-r11 as they are volatile, i.e. don't need* to be saved
+ * by the callee, and except for r11 are not implicit parameters to any
+ * instructions.  Ideally, fixup would use r8-r10 and thus avoid implicit
+ * parameters entirely, but Hyper-V's hypercall ABI uses r8 and testing Hyper-V
+ * is higher priority than testing non-faulting SYSCALL/SYSRET.
+ *
+ * Note, the fixup handler deliberately does not handle #DE, i.e. the vector
+ * is guaranteed to be non-zero on fault.
+ *
+ * REGISTER INPUTS:
+ * r9  = MAGIC
+ * r10 = RIP
+ * r11 = new RIP on fault
