To enable smp_processor_id() and might_sleep() debug checks earlier, it's required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING. get_nid_for_pfn() checks for system_state == BOOTING to decide whether to use early_pfn_to_nid() when CONFIG_DEFERRED_STRUCT_PAGE_INIT=y. That check is dubious, because the switch to state RUNNING happes way after page_alloc_init_late() has been invoked. Change the check to less than RUNNING state so it covers the new intermediate states as well.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
