Merge staging-next tree into Linus's latest version
Conflicts:
drivers/staging/arlan/arlan-main.c
drivers/staging/comedi/drivers/cb_das16_cs.c
drivers/staging/cx25821/cx25821-alsa.c
drivers/staging/dt3155/dt3155_drv.c
drivers/staging/hv/hv.c
drivers/staging/netwave/netwave_cs.c
drivers/staging/wavelan/wavelan.c
drivers/staging/wavelan/wavelan_cs.c
drivers/staging/wlags49_h2/wl_cs.c
This required a bit of hand merging due to the conflicts
that happened in the later .34-rc releases, as well as
some staging driver changing coming in through other trees
(v4l and pcmcia).
