use PF_POPULATE for resolving delegated page faults
...
Since a host side PTE does not follow McKernel's copying a COW page,
COW pages cannot be used for resolving delegated page faults.
Therefore, to copy pages eagerly, PF_POPULATE should be used.

ptrace: add error stub to prevent mcexec from waiting
...
In LTP's ptrace03 test,
there is a exit() preceded by ptrace(PTRACE_TRACEME).
In this case, processes will be usually finished immediately.
But mcexec will fall into waiting for parent's ptrace(PTRACE_CONT),
because mcexec sends itself a signal in processing of exit().
