Defined local_softirq_pending_ref macro and get rid of {local, set, or}
_softirq_pending macros. use {local, set, or}_softirq_pending
in <linux/interrupt.h> that rely on per-CPU mutators.

S390_lowcore is not a per-CPU variable, so it cannot be accessed with
__this_cpu_read/write...
"lowcore" is a kind of hardware "per-CPU" area on s390. Each cpu accessing
first 2 pages at the real address 0 is actually touching pages at the
"absolute" address specified by prefix register of this cpu.
