commit9a78e15802upstream. VMX also uses KVM_REQ_GET_NESTED_STATE_PAGES for the Hyper-V eVMCS, which may need to be loaded outside guest mode. Therefore we cannot WARN in that case. However, that part of nested_get_vmcs12_pages is _not_ needed at vmentry time. Split it out of KVM_REQ_GET_NESTED_STATE_PAGES handling, so that both vmentry and migration (and in the latter case, independent of is_guest_mode) do the parts that are needed.

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.
