[ Upstream commit eabb7f1ace53e127309407b2b5e74e8199e85270 ] 1. Var debug_objects_allocated tracks valid kmem_cache_alloc calls, so track it in debug_objects_replace_static_objects. Do similar things in object_cpu_offline. 2. In debug_objects_mem_init, there is no need to call function cpuhp_setup_state_nocalls when debug_objects_enabled = 0 (out of memory).

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.
