Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "This is the bulk of the s390 patches for the 3.11 merge window. Notable enhancements are: the block timeout patches for dasd from Hannes, and more work on the PCI support front. In addition some cleanup and the usual bug fixing." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (42 commits) s390/dasd: Fail all requests when DASD_FLAG_ABORTIO is set s390/dasd: Add 'timeout' attribute block: check for timeout function in blk_rq_timed_out() block/dasd: detailed I/O errors s390/dasd: Reduce amount of messages for specific errors s390/dasd: Implement block timeout handling s390/dasd: process all requests in the device tasklet s390/dasd: make number of retries configurable s390/dasd: Clarify comment s390/hwsampler: Updated misleading member names in hws_data_entry s390/appldata_net_sum: do not use static data s390/appldata_mem: do not use static data s390/vmwatchdog: do not use static data s390/airq: simplify adapter interrupt code s390/pci: remove per device debug attribute s390/dma: remove gratuitous brackets s390/facility: decompose test_facility() s390/sclp: remove duplicated include from sclp_ctl.c s390/irq: store interrupt information in pt_regs s390/drivers: Cocci spatch "ptr_ret.spatch" ...
