[ Upstream commit 84cf78dcd9d65c45ab73998d4ad50f433d53fb93 ] Mark pages accessed before dropping mmu_lock when faulting in guest memory so that shadow_map() can convert to kvm_release_faultin_page() without tripping its lockdep assertion on mmu_lock being held. Marking pages accessed outside of mmu_lock is ok (not great, but safe), but marking pages _dirty_ outside of mmu_lock can make filesystems unhappy.

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.
