Subject: mm: page_alloc: call panic() when memoryless node allocation fails
Date: Sun, 12 Feb 2023 19:10:27 +0800

In free_area_init(), we will continue to run after allocation of
memoryless node pgdat fails.  However, in the subsequent process (such as
when initializing zonelist), the case that NODE_DATA(nid) is NULL is not
handled, which will cause panic.  Instead of this, it's better to call
panic() directly when the memory allocation fails during system boot.
