Main changes: - COW optimization for safecopy. - safemap, a grant-based interface for sharing memory regions between processes. - Integration with safemap and complete rework of DS, supporting new data types natively (labels, memory ranges, memory mapped ranges). - For further information: http://wiki.minix3.org/en/SummerOfCode2009/MemoryGrants Additional changes not included in the original Wu's branch: - Fixed unhandled case in VM when using COW optimization for safecopy in case of a block that has already been shared as SMAP. - Better interface and naming scheme for sys_saferevmap and ds_retrieve_map calls. - Better input checking in syslib: check for page alignment when creating memory mapping grants. - DS notifies subscribers when an entry is deleted. - Documented the behavior of indirect grants in case of memory mapping. - Test suite in /usr/src/test/safeperf|safecopy|safemap|ds/* reworked and extended. - Minor fixes and general cleanup. - TO-DO: Grant ids should be generated and managed the way endpoints are to make sure grant slots are never misreused.
