Get the kvm pointer from the caller, rather than deriving it from vcpu->kvm, and plumb the kvm pointer all the way from kvm_mmu_get_shadow_page(). With this change in place, the vcpu pointer is only needed to sync indirect shadow pages. In other words, __kvm_mmu_get_shadow_page() can now be used to get *direct* shadow pages without a vcpu pointer. This enables eager page splitting, which needs to allocate direct shadow pages during VM ioctls. No functional change intended.

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.
