Sean Christopherson c060c72ffe KVM: x86/mmu: Expand collapsible SPTE zap for TDP MMU to ZONE_DEVICE and HugeTLB pages 
Zap SPTEs that are backed by ZONE_DEVICE pages when zappings SPTEs to
rebuild them as huge pages in the TDP MMU.  ZONE_DEVICE huge pages are
managed differently than "regular" pages and are not compound pages.
Likewise, PageTransCompoundMap() will not detect HugeTLB, so switch
to PageCompound().

This matches the similar check in kvm_mmu_zap_collapsible_spte.

README 

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.
