  memblock: don't touch memblock arrays when memblock_free() is called late (2026-05-25 20:48:14 +0300)

memblock: fix regression from memblock_free_late() refactoring

After refactoring of memblock_free_late() and free_init_pages() it became
possible to call memblock_free() after memblock init data was discarded.

Make sure memblock_free() does not touch memblock.reserved unless it is
called early enough or when ARCH_KEEP_MEMBLOCK is enabled.
