Subject: [PATCH] x86: numa: include asm/pgtable_areas.h

From: Arnd Bergmann <arnd@...db.de>

The __vmalloc_start_set declaration is in a header that is not included
in numa_32.c in current linux-next:

arch/x86/mm/numa_32.c: In function 'initmem_init':
arch/x86/mm/numa_32.c:57:9: error: '__vmalloc_start_set' undeclared (first use in this function)
   57 |         __vmalloc_start_set = true;
      |         ^~~~~~~~~~~~~~~~~~~
arch/x86/mm/numa_32.c:57:9: note: each undeclared identifier is reported only once for each function it appears in

Add an explicit #include

This showed up in linux-next after 6.8-rc1, but could not immediately see what changed.
