x86/boot/e820: Create coherent API function names for E820 range operations
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.
