The host CR3 in the vcpu thread can only be changed when scheduling, so commit 15ad9762d69f ("KVM: VMX: Save HOST_CR3 in vmx_prepare_switch_to_guest()") changed vmx.c to only save it in vmx_prepare_switch_to_guest(). However, it also has to be synced in vmx_sync_vmcs_host_state() when switching VMCS. vmx_set_host_fs_gs() is called in both places, so rename it to vmx_set_vmcs_host_state() and make it update HOST_CR3.

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.
