vmx_save_host_state() is only called from kvm_arch_vcpu_ioctl_run() so the context is pretty well defined and as we're past 'swapgs' MSR_GS_BASE should contain kernel's GS base which we point to irq_stack_union. Add new kernelmode_gs_base() API, irq_stack_union needs to be exported as KVM can be build as module.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
