The vgic debug iterator is the final user of vgic_copy_lpi_list(), but is a bit more complicated to transition to something else. Use a mark in the LPI xarray to record the indices 'known' to the debug iterator. Protect against the LPIs from being freed by associating an additional reference with the xarray mark. Rework iter_next() to let the xarray walk 'drive' the iteration after visiting all of the SGIs, PPIs, and SPIs.

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.
