When CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, the initialization of reserved pages may cause access of NODE_DATA() with invalid nid and crash. Add a fall back to early_pfn_to_nid() in memmap_init_reserved_pages() to ensure a valid node id is always passed to init_reserved_page(). -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEeOVYVaWZL5900a/pOQOGJssO/ZEFAmW19ekQHHJwcHRAa2Vy bmVsLm9yZwAKCRA5A4Ymyw79kQ2CCAC+aXkQdFbP08jyZ1Q3rjZpXMAq6xORVT1z fWFQQlAQ2L75dWR2dUh+lFPAQRLhs1KfUUmwZUczKhyWXpCFsLLT5OgLtfDLk/sB XzoyZeW7//pSY22mFxcVmOMuJBZ3q+ZB0n9LdhIaWcdedltvEFhVXZjVPFJszszb 8BZIq7tKvUFUv8KOlfGTvjvNjhjmXRRmcrG1fsS4sdkHQ8/36/KjqI0sZUgMq7Fz HfawJ6bK+ysHBmKCuWRAU4ssiuUGSaivqh8Azt+FI/zr2Dk+40asFpE0573VMNB7 MaXAn9TjXKU6e/wMBB7KQSUqIlv3Pm7iK2+B/IP4AJ1cWLylRO1r =efaB -----END PGP SIGNATURE----- Merge tag 'fixes-2024-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock Pull memblock fix from Mike Rapoport: "Fix crash when reserved memory is not added to 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.
