Move the code that write-protects newly-shadowed guest page tables into account_shadowed(). This avoids a extra gfn-to-memslot lookup and is a more logical place for this code to live. But most importantly, this reduces kvm_mmu_alloc_shadow_page()'s reliance on having a struct kvm_vcpu pointer, which will be necessary when creating new shadow pages during VM ioctls for eager page splitting. Note, it is safe to drop the role.level == PG_LEVEL_4K check since account_shadowed() returns early if role.level > PG_LEVEL_4K. 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.
