kmsan_internal_memmove_metadata() transitively calls stack_depot_save() (via kmsan_internal_chain_origin() and kmsan_save_stack_with_flags()), which may allocate memory. Guard it with kmsan_enter_runtime() and kmsan_leave_runtime() to avoid recursion.

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.
