Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (31 commits)
[S390] disassembler: mark exception causing instructions
[S390] Enable exception traces by default
[S390] return address of compat signals
[S390] sysctl: get rid of dead declaration
[S390] dasd: fix fixpoint divide exception in define_extent
[S390] dasd: add sanity check to detect path connection error
[S390] qdio: fix kernel panic for zfcp 31-bit
[S390] Add s390x description to Documentation/kdump/kdump.txt
[S390] Add VMCOREINFO_SYMBOL(high_memory) to vmcoreinfo
[S390] dasd: fix expiration handling for recovery requests
[S390] outstanding interrupts vs. smp_send_stop
[S390] ipc: call generic sys_ipc demultiplexer
[S390] zcrypt: Fix error return codes.
[S390] zcrypt: Rework length parameter checking.
[S390] cleanup trap handling
[S390] Remove Kerntypes leftovers
[S390] topology: increase poll frequency if change is anticipated
[S390] entry[64].S improvements
[S390] make arch/s390 subdirectories depend on config option
[S390] kvm: move cmf host id constant out of lowcore
...
Fix up conflicts in arch/s390/kernel/{smp.c,topology.c} due to the
sysdev removal clashing with "topology: get rid of ifdefs" which moved
some of that code around.
