As a result, stale TLB entries can remain after resuming the guest. In practice, this manifests as a missing EPT_VIOLATION or #VE exception when the guest subsequently accesses a page which has had its permissions reduced. vmx_vmenter_helper() now has 11 p2ms to potentially invalidate, but issuing 11 INVEPT instructions isn't clever. Instead, count how many contexts need invalidating, and use INVEPT_ALL_CONTEXT if two or more are in need of flushing. This doesn't have an XSA because altp2m is not yet a security-supported feature.

After #VE has been set up, the guest can balloon out and free the nominated GFN, after which the processor may write to it. Also, the unlocked GFN query means the MFN is stale by the time it is used. Alternatively, a guest can race two disable calls to cause one VMCS to still reference the nominated GFN after the tracking information was dropped. Rework the logic from scratch to make it safe. Hold an extra page reference on the underlying frame, to account for the VMCS's reference. This means that if the GFN gets ballooned out, it isn't freed back to Xen until #VE is disabled, and the VMCS no longer refers to the page. A consequence of this is that altp2m_vcpu_disable_ve() needs to be called during the domain_kill() path, to drop the reference for domains which shut down with #VE still enabled. For domains using altp2m, we expect a single enable call and no disable for the remaining lifetime of the domain. However, to avoid problems with concurrent calls, use cmpxchg() to locklessly maintain safety. This doesn't have an XSA because altp2m is not yet a security-supported feature.
