Use bools to track write and user faults throughout the page fault paths and down into mmu_set_spte(). The actual usage is purely boolean, but that's not obvious without digging into all paths as the current code uses a mix of bools (TDP and try_async_pf) and ints (shadow paging and mmu_set_spte()). No true functional change intended (although the pgprintk() will now print 0/1 instead of 0/PFERR_WRITE_MASK).

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.
