    x86/boot/e820: Create coherent API function names for E820 range operations · ab6bc04c
    Ingo Molnar authored
    We have these three related functions:
    
     extern void e820_add_region(u64 start, u64 size, int type);
     extern u64  e820_update_range(u64 start, u64 size, unsigned old_type, unsigned new_type);
     extern u64  e820_remove_range(u64 start, u64 size, unsigned old_type, int checktype);
    
    But it's not clear from the naming that they are 3 operations based around the
    same 'memory range' concept. Rename them to better signal this, and move
    the prototypes next to each other:
    
     extern void e820__range_add   (u64 start, u64 size, int type);
     extern u64  e820__range_update(u64 start, u64 size, unsigned old_type, unsigned new_type);
     extern u64  e820__range_remove(u64 start, u64 size, unsigned old_type, int checktype);
    
    Note that this improved organization of the functions shows another problem that was easy
    to miss before: sometimes the E820 entry type is 'int', sometimes 'unsigned int' - but this
    will be fixed in a separate patch.
    
    No change in functionality.
