Description
Despite the recent improvements in IPC, which can now pass as many as 4 payload arguments in registers, the reply goes from kernel to a userspace task always in memory. Theoretically, this could be improved for short replies by "soaking" the task into the kernel and populating the registers with the contents of the reply. Long replies will go through memory as usual.
