PVH guest needs PV extentions to work, so "nopv" parameter should be ignored for PVH but not for HVM guest. If PVH guest boots up via the Xen-PVH boot entry, xen_pvh is set early, we know it's PVH guest and ignore "nopv" parameter directly. If PVH guest boots up via the normal boot entry same as HVM guest, it's hard to distinguish PVH and HVM guest at that time. In this case, we have to panic early if PVH is detected and nopv is enabled to avoid a worse situation later. Remove static from bool_x86_init_noop/x86_op_int_noop so they could be used globally. Move xen_platform_hvm() after xen_hvm_guest_late_init() to avoid compile error.

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.
