s390/zcore: copy vector registers into the image data
The /sys/kernel/debug/zcore/mem interface delivers the memory of the old system with the CPU registers stored to the assigned locations in each prefix page. For the vector registers the prefix page of each CPU has an address of a 1024 byte save area at 0x11b0. But the /sys/kernel/debug/zcore/mem interface fails copy the vector registers saved at boot of the zfcpdump kernel into the dump image. Copy the saved vector registers of a CPU to the outout buffer if the memory area that is read via /sys/kernel/debug/zcore/mem intersects with the vector register save area of this CPU.
