Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Martin Schwidefsky:
"Two patches to save some memory if CONFIG_NR_CPUS is large, a changed
default for the use of compare-and-delay, and a couple of bug fixes"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/spinlock: disabled compare-and-delay by default
s390/mm: align 64-bit PIE binaries to 4GB
s390/cacheinfo: coding style changes
s390/cacheinfo: fix shared cpu masks
s390/smp: reduce size of struct pcpu
s390/topology: convert cpu_topology array to per cpu variable
s390/topology: delay initialization of topology cpu masks
s390/vdso: fix clock_gettime for CLOCK_THREAD_CPUTIME_ID, -2 and -3
