Change the PSE hugepage handling in walk_addr_generic() to fire on any page level greater than PT_PAGE_TABLE_LEVEL, a.k.a. PG_LEVEL_4K. PSE paging only has two levels, so "== 2" and "> 1" are functionally the same, i.e. this is a nop. A future patch will drop KVM's PT_*_LEVEL enums in favor of the kernel's PG_LEVEL_* enums, at which point "walker->level == PG_LEVEL_2M" is semantically incorrect (though still functionally ok). No functional change intended.

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.
