Remove pagex pseudo page fault code. It does not work together with the system call speedup that makes the complete system call path enabled for interrupts. To make pagex and the syscall speedup code work together we would have to add code to the program check handler to do a critical section cleanup like the asynchronous interrupt code. This would make program checks slower. Not what we want. Newer versions of z/VM have the improved pfault pseudo page fault interface. This replaces the old pagex interface and does not have the problem. So its better to just rip out the pagex code.
