User mode can't be trusted to provide the kernel buffers for internal use. The syscall for k_pipe_init() has been removed in favor of a new API to draw the buffer memory from the calling thread's resource pool. K_PIPE_DEFINE() now properly locates the allocated buffer into kernel memory. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
