+ mds_user_clear.
+
+ The mitigation is invoked in prepare_exit_to_usermode() which covers
+- most of the kernel to user space transitions. There are a few exceptions
+- which are not invoking prepare_exit_to_usermode() on return to user
+- space. These exceptions use the paranoid exit code.
++ all but one of the kernel to user space transitions. The exception
++ is when we return from a Non Maskable Interrupt (NMI), which is
++ handled directly in do_nmi().
+
+- - Non Maskable Interrupt (NMI):
+-
+- Access to sensible data like keys, credentials in the NMI context is
+- mostly theoretical: The CPU can do prefetching or execute a
+- misspeculated code path and thereby fetching data which might end up
+- leaking through a buffer.
+-
+- But for mounting other attacks the kernel stack address of the task is
+- already valuable information. So in full mitigation mode, the NMI is
+- mitigated on the return from do_nmi() to provide almost complete
+- coverage.
+-
+- - Double fault (#DF):
+-
+- A double fault is usually fatal, but the ESPFIX workaround, which can
+- be triggered from user space through modify_ldt(2) is a recoverable
+- double fault. #DF uses the paranoid exit path, so explicit mitigation
+- in the double fault handler is required.
+-
+- - Machine Check Exception (#MC):
+-
+- Another corner case is a #MC which hits between the CPU buffer clear
+- invocation and the actual return to user. As this still is in kernel
+- space it takes the paranoid exit path which does not clear the CPU
+- buffers. So the #MC handler repopulates the buffers to some
+- extent. Machine checks are not reliably controllable and the window is
+- extremly small so mitigation would just tick a checkbox that this
+- theoretical corner case is covered. To keep the amount of special
+- cases small, ignore #MC.
+-
+- - Debug Exception (#DB):
+-
+- This takes the paranoid exit path only when the INT1 breakpoint is in
+- kernel space. #DB on a user space address takes the regular exit path,
+- so no extra mitigation required.
++ (The reason that NMI is special is that prepare_exit_to_usermode() can
++ enable IRQs. In NMI context, NMIs are blocked, and we don't want to
++ enable IRQs with NMIs blocked.)
