Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "There is only one new feature in this pull for the 4.4 merge window, most of it is small enhancements, cleanup and bug fixes: - Add the s390 backend for the software dirty bit tracking. This adds two new pgtable functions pte_clear_soft_dirty and pmd_clear_soft_dirty which is why there is a hit to arch/x86/include/asm/pgtable.h in this pull request. - A series of cleanup patches for the AP bus, this includes the removal of the support for two outdated crypto cards (PCICC and PCICA). - The irq handling / signaling on buffer full in the runtime instrumentation code is dropped. - Some micro optimizations: remove unnecessary memory barriers for a couple of functions: [smb_]rmb, [smb_]wmb, atomics, bitops, and for spin_unlock. Use the builtin bswap if available and make test_and_set_bit_lock more cache friendly. - Statistics and a tracepoint for the diagnose calls to the hypervisor. - The CPU measurement facility support to sample KVM guests is improved. - The vector instructions are now always enabled for user space processes if the hardware has the vector facility. This simplifies the FPU handling code. The fpu-internal.h header is split into fpu internals, api and types just like x86. - Cleanup and improvements for the common I/O layer. - Rework udelay to solve a problem with kprobe. udelay has busy loop semantics but still uses an idle processor state for the wait" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (66 commits) s390: remove runtime instrumentation interrupts s390/cio: de-duplicate subchannel validation s390/css: unneeded initialization in for_each_subchannel s390/Kconfig: use builtin bswap s390/dasd: fix disconnected device with valid path mask s390/dasd: fix invalid PAV assignment after suspend/resume s390/dasd: fix double free in dasd_eckd_read_conf s390/kernel: fix ptrace peek/poke for floating point registers s390/cio: move ccw_device_stlck functions s390/cio: move ccw_device_call_handler s390/topology: reduce per_cpu() invocations s390/nmi: reduce size of percpu variable s390/nmi: fix terminology s390/nmi: remove casts s390/nmi: remove pointless error strings s390: don't store registers on disabled wait anymore s390: get rid of __set_psw_mask() s390/fpu: split fpu-internal.h into fpu internals, api, and type headers s390/dasd: fix list_del corruption after lcu changes s390/spinlock: remove unneeded serializations at unlock ...
