Pull SCSI target fixes from Nicholas Bellinger: "These are mostly minor fixes this time around. The iscsi-target CHAP big-endian bugfix and bump FD_MAX_SECTORS=2048 default patch to allow 1MB sized I/Os for FILEIO backends on >= v3.5 code are both CC'ed to stable. Also, there is a persistent reservations regression that has recently been reported for >= v3.8.x code, that is currently being tracked down for v3.9." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target/pscsi: Reject cross page boundary case in pscsi_map_sg target/file: Bump FD_MAX_SECTORS to 2048 to handle 1M sized I/Os tcm_vhost: Flush vhost_work in vhost_scsi_flush() tcm_vhost: Add missed lock in vhost_scsi_clear_endpoint() target: fix possible memory leak in core_tpg_register() target/iscsi: Fix mutual CHAP auth on big-endian arches target_core_sbc: use noop for SYNCHRONIZE_CACHE

When KMS has parsed an EDID "detailed timing", it leaves the frame rate zeroed. Consecutive (debug-) output of that mode thus yields 0 for vsync. This simple fix also speeds up future invocations of drm_mode_vrefresh(). While it is debatable whether this qualifies as a -stable fix I'd apply it for consistency's sake; drm_helper_probe_single_connector_modes() does the same thing already for all probed modes.

EDID spreads some values across multiple bytes; bit-fiddling is needed to retrieve these. The current code to parse "detailed timings" has a cut&paste error that results in a vsync offset of at most 15 lines instead of 63. See http://en.wikipedia.org/wiki/EDID and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why that needs to be a left shift.

On some revisions of AT91 SoCs, the RTC IMR register is not working. Instead of elaborating a workaround for that specific SoC or IP version, we simply use a software variable to store the Interrupt Mask Register and modify it for each enabling/disabling of an interrupt. The overhead of this is negligible anyway. The interrupt mask register (IMR) for the RTC is broken on the AT91SAM9x5 sub-family of SoCs (good overview of the members here: http://www.eewiki.net/display/linuxonarm/AT91SAM9x5 ). The "user visible effect" is the RTC doesn't work. That sub-family is less than two years old and only has devicetree (DT) support and came online circa lk 3.7 . The dust is yet to settle on the DT stuff at least for AT91 SoCs (translation: lots of stuff is still broken, so much that it is hard to know where to start). The fix in the patch is pretty simple: just shadow the silicon IMR register with a variable in the driver. Some older SoCs (pre-DT) use the the rtc-at91rm9200 driver (e.g. obviously the AT91RM9200) and they should not be impacted by the change. There shouldn't be a large volume of interrupts associated with a RTC.
