[ Upstream commit7671ce21b1] In preparation of supporting checkpoint/restore for nested state, commitca0bde28f2("kvm: nVMX: Split VMCS checks from nested_vmx_run()") modified check_vmentry_postreqs() to only perform the guest EFER consistency checks when nested_run_pending is true. But, in the normal nested VMEntry flow, nested_run_pending is only set after check_vmentry_postreqs(), i.e. the consistency check is being skipped. Alternatively, nested_run_pending could be set prior to calling check_vmentry_postreqs() in nested_vmx_run(), but placing the consistency checks in nested_vmx_enter_non_root_mode() allows us to split prepare_vmcs02() and interleave the preparation with the consistency checks without having to change the call sites of nested_vmx_enter_non_root_mode(). In other words, the rest of the consistency check code in nested_vmx_run() will be joining the postreqs checks in future patches.

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.
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.
