I wanted to merge it, but pagecache will be in highmem as well, and the
above only takes into account the normal classzone (so it can be off by
63G).
Also I'd prefer page_cache_init() to be recalled within
free_all_bootmem/free_all_bootmem_node, so we don't need to change all
archs. to take highmem into account we can use the globals
highstart_pfn/highend_pfn within an #ifdef CONFIG_HIGHMEM.
Are you interested in fixing it? Otherwise let me know. Thanks!
Andrea
