In the case of #DE, the latched result from the previous DIV to execute will be forwarded speculatively. This is an interesting covert channel that allows two threads to communicate without any system calls. In also allows userspace to obtain the result of the most recent DIV instruction executed (even speculatively) in the core, which can be from a higher privilege context. Scrub the result from the divider by executing a non-faulting divide. This needs performing on the exit-to-guest paths, and ist_exit-to-Xen. Alternatives in IST context is believed safe now that it's done in NMI context. This is XSA-439 / CVE-2023-20588.

Wrap the heuristic into a pair of predicates rather than opencoding it, and the explanation of the heuristic, at each usage site.

In order to compensate, issue VERW when exiting to Xen from an IST entry. SPEC_CTRL_EXIT_TO_XEN already has two reads of spec_ctrl_flags off the stack, and we're about to add a third. Load the field into %ebx, and list the register as clobbered. %r12 has been arranged to be the ist_exit signal, so add this as an input dependency and use it to identify when to issue a VERW.

This register is zero elsewhere in the entry/exit asm, so it only needs setting in the IST path. As this is subtle and fragile, add check_ist_exit() to be used in debugging builds to cross-check that the ist_exit boolean matches the entry vector. Write check_ist_exit() it in C, because it's debug only and the logic more complicated than I care to maintain in asm. For now, we only need to use this signal in the exit-to-Xen path, but some exit-to-guest paths happen in IST context too. Check the correctness in all exit paths to avoid the logic bit-rotting.

Doing so highlights that SPEC_CTRL_EXIT_TO_XEN is missing a VERW flush for the corner case when e.g. an NMI hits late in an exit-to-guest path. Leave a TODO, which will be addressed in subsequent patches which arrange for VERW flushing to be safe within SPEC_CTRL_EXIT_TO_XEN.

Fold DO_SPEC_CTRL_EXIT_TO_XEN into SPEC_CTRL_EXIT_TO_XEN to simplify further fixes. When merging labels, switch the name to .L\@_skip_sc_msr as "skip" on its own is going to be too generic shortly.
