From: Luca Dariz
Subject: [PATCH 0/7] update rpc for x86_64
Date: Mon, 16 Jan 2023 11:58:50 +0100

These patches address the comments raised in the previous submission
and add support for 32-bit rpc and syscalls on a 64-bit kernel.

Luca Dariz (7):
  add msg_user_header_t for user-side msg structure
  x86_64: expand and shrink messages in copy{in,out}msg routines
  update syscall signature with rpc_vm_* and mach_port_name_t
  update writev syscall signature with rpc types
  adjust rdxtree key to the correct size
  add conversion helpers for invalid mach port names
  replace mach_port_t with mach_port_name_t
