Could you add some documentation about 'how to use' your generic funcs ?
I think more archs can use your generic routine if well documented.
All initialization path can be written in following way ?
==
for_all_memory_region()
add_active_range(nid, start, end)
free_area_init_nodes(max_dma, max_dma32, max_low_pfn, max_pfn);
==
And following functions are really needed ?
==
+extern void remove_all_active_ranges(void);
+extern void get_pfn_range_for_nid(unsigned int nid,
+ unsigned long *start_pfn, unsigned long *end_pfn);
+extern unsigned long find_min_pfn_with_active_regions(void);
+extern unsigned long find_max_pfn_with_active_regions(void);
+extern int early_pfn_to_nid(unsigned long pfn);
+extern void free_bootmem_with_active_regions(int nid,
+ unsigned long max_low_pfn);
+extern void sparse_memory_present_with_active_regions(int nid);
+extern unsigned long absent_pages_in_range(unsigned long start_pfn,
+ unsigned long end_pfn);
