[ Upstream commit b7031fd40fcc741b0f9b0c04c8d844e445858b84 ]
Reset the vm_{entry,exit}_controls_shadow variables as well as the
segment cache after loading a new VMCS in vmx_switch_vmcs(). The
shadows/cache track VMCS data, i.e. they're stale every time we
switch to a new VMCS regardless of reason.
This fixes a bug where stale control shadows would be consumed after
a nested VMExit due to a failed consistency check.

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.
