Return a u64, not an int, from mmu_spte_clear_track_bits(). The return value is the old SPTE value, which is very much a 64-bit value. The sole caller that consumes the return value, drop_spte(), already uses a u64. The only reason that truncating the SPTE value is not problematic is because drop_spte() only queries the shadow-present bit, which is in the lower 32 bits.

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.
