Paolo,

please pull the fixes for the following two problems:
 - The PQAP instruction did not set the CC in all occasions
 - We observed crashes with nested guests because a pointer to struct
   kvm was accessed before being valid (resulting in NULL pointers).

You'll see that the fixes are still based on 6.7-rc4 since they've
lived on our master for quite a while. But I've re-based them on
Linus' master and your queue and next branches without an issue.

The following changes since commit 4cdf351d3630a640ab6a05721ef055b9df62277f:

  KVM: SVM: Update EFER software model on CR0 trap for SEV-ES (2023-12-08 13:37:05 -0500)
