Drop the .post_leave_smm() emulator callback, which at this point is just a wrapper to kvm_mmu_reset_context(). The manual context reset is unnecessary, because unlike enter_smm() which calls vendor MSR/CR helpers directly, em_rsm() bounces through the KVM helpers, e.g. kvm_set_cr4(), which are responsible for processing side effects. em_rsm() is already subtly relying on this behavior as it doesn't manually do kvm_update_cpuid_runtime(), e.g. to recognize CR4.OSXSAVE changes.

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 Restructured Text 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.
