Pull more parisc updates from Helge Deller:

 - During this merge window O_NONBLOCK was changed to become 000200000,
   but we missed that the syscalls timerfd_create(), signalfd4(),
   eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
   bit-wise check of the flags parameter.

   To provide backward compatibility with existing userspace we
   introduce parisc specific wrappers for those syscalls which filter
   out the old O_NONBLOCK value and replaces it with the new one.

 - Prevent HIL bus driver to get stuck when keyboard or mouse isn't
   attached

 - Improve error return codes when setting rtc time

 - Minor documentation fix in pata_ns87415.c

Hence the DMA boundary mask supplied by its driver was silently ignored, as __scsi_init_queue() doesn't check the return value of dma_set_seg_boundary(), and the default value of 0xffffffff was used. Now the device has gained DMA parameters, the driver-supplied value is used, and the following warning is printed on Salvator-XS: DMA-API: sata_rcar ee300000.sata: mapping sg segment across boundary [start=0x00000000ffffe000] [end=0x00000000ffffefff] [boundary=0x000000001ffffffe] WARNING: CPU: 5 PID: 38 at kernel/dma/debug.c:1233 debug_dma_map_sg+0x298/0x300 (the range of start/end values depend on whether IOMMU support is enabled or not) The issue here is that SATA_RCAR_DMA_BOUNDARY doesn't have bit 0 set, so any typical end value, which is odd, will trigger the check.
