Gerald Schaefer b2d24b97b2 s390/kernel: add support for kernel address space layout randomization (KASLR) 
This patch adds support for relocating the kernel to a random address.
The random kernel offset is obtained from cpacf, using either TRNG, PRNO,
or KMC_PRNG, depending on supported MSA level.

KERNELOFFSET is added to vmcoreinfo, for crash --kaslr support.
