Move the lockdep_assert_held_write(&kvm->mmu_lock) from the only one caller kvm_tdp_mmu_clear_dirty_pt_masked() to inside clear_dirty_pt_masked(). This change makes it more obvious why it's safe for clear_dirty_pt_masked() to use the non-atomic (for non-volatile SPTEs) tdp_mmu_clear_spte_bits() helper. for_each_tdp_mmu_root() does its own lockdep, so the only "loss" in lockdep coverage is if the list is completely empty.

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.
