With commit 0c24e06119 ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.
Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.

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.
