__next_free_mem_range - next function for for_each_free_mem_range() : pointer to u64 loop variable : nid: node selector, MAX_NUMNODES for all nodes : ptr to phys_addr_t for start address of the range, can be NULL : ptr to phys_addr_t for end address of the range, can be NULL : ptr to int for nid of the range, can be NULL
Find the first free area from * which matches , fill the out parameters, and update * for the next iteration. The lower 32bit of * contains index into memory region and the upper 32bit indexes the areas before each reserved region. For example, if reserved regions look like the following,
0:[0-16), 1:[32-48), 2:[128-130)
The upper 32bit indexes the following regions.
0:[0-0), 1:[16-32), 2:[48-128), 3:[130-MAX)
As both region arrays are sorted, the function advances the two indices in lockstep and returns each intersection.
