* Unmaps all memory occupied by the carve_desc region from the
* list entry pointed to by map.
*
* Returns 1 if carving was performed or 0 if the regions don't overlap.
* Returns -1 if it would affect non-RAM regions but overlap_only_ram is set.
* Carving is only guaranteed to complete when all regions return 0.
* Returns EFI_CARVE_NO_OVERLAP if the regions don't overlap.
* Returns EFI_CARVE_OVERLAPS_NONRAM if the carve and map overlap,
* and the map contains anything but free ram.
* (only when overlap_only_ram is true)
* Returns EFI_CARVE_LOOP_AGAIN if the mapping list should be traversed
* again, as it has been altered
* Returns the number of overlapping pages. The pages are removed from
* the mapping list.
*
* In case of EFI_CARVE_OVERLAPS_NONRAM it is the callers responsibility
* to readd the already carved out pages to the mapping.
