That's technically wrong. It still can launch an attack, but the attack
wont

With enhanced IBRS in use, the application running on sibling CPU will not
be able to launch Spectre v2 attack to the application on current CPU.
There is no need to use STIBP for this case. Disable the STIBP code
when enhanced IBRS is used.

With enhanced IBRS in use, the application running on sibling CPU will not
be able to launch Spectre v2 attack to the application on current CPU.
There is no need to use STIBP for this case. Disable the STIBP code
when enhanced IBRS is used.
