All SNP APs are initially started using the APIC INIT/SIPI sequence in the guest. This sequence moves the AP MP state from KVM_MP_STATE_UNINITIALIZED to KVM_MP_STATE_RUNNABLE, so there is no need to attempt the UNBLOCK. As it is, the UNBLOCK support in SVM is only enabled when AVIC is enabled. When AVIC is disabled, AP creation is still successful. Remove the KVM_REQ_UNBLOCK request from the AP creation code and revert the changes to the vcpu_unblocking() kvm_x86_ops path.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
