Store the gpa used to unprotect the faulting gfn for retry as a gpa_t, not an unsigned long. This fixes a bug where 32-bit KVM would unprotect and retry the wrong gfn if the gpa had bits 63:32!=0. In practice, this bug is functionally benign, as unprotecting the wrong gfn is purely a performance issue (thanks to the anti-infinite-loop logic). And of course, almost no one runs 32-bit KVM these days.

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 reStructuredText 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.
