  Log:
  Now that we define user mode as any IP address that isn't in the
  kernel's VA regions, we cannot limit the use of break-based
  syscalls to user mode only. The signal trampolines are in the
  gateway page, which is mapped into the process address space in
  region 5 and thus is kernel space.
  
  We don't special case the gateway page here. Allow break-based
  syscalls from anywhere in the kernel VA space.
