Merge branch 'bpf-s390-implement-get_preempt_count'
Ilya Leoshkevich says:
====================
bpf/s390: Implement get_preempt_count()
This series adds get_preempt_count() BPF implementation for s390.
On s390 preempt_count lives in lowcore: a per-cpu data structure
mapped at virtual address 0 or 0x70000 depending on the kernel
command line.
Patch 1 adds a kfunc to obtain lowcore address.
Patch 2 is the implementation that delegates to it.
