## Summary POSIX requires that the shm objects are zero-initialized. This has been broken in some earlier commits (starting from https://github.com/apache/nuttx/commit/9af5fc5d09724a5d300bc07ce85b9ba5c01ffadd) Also fix the flat build memory allocation to allocate both object data and payload in the same chunk (as the comment also suggests). This saves allocations and memory in a system with lots of shm objects. This PR fixes errors in applications, which run in "CONFIG_BUILD_FLAT", and assume that newly allocated shared memory is zero-initialized. This also reduces memory consumption in smaller devices, when each shared memory object is allocated in a single chunk as originally. The errors were introduced earlier when the SHM allocations were cache-line aligned.
