hwmon: (zl6100) Enable interval between chip accesses for all chips

2012-03-19T16:02:36+00:00

commit fecfb64422d91a9621a3f96ab75c3a5f13e80b58 upstream.

Intersil reports that all chips supported by the zl6100 driver require
an interval between chip accesses, even ZL2004 and ZL6105 which were thought
to be safe.

target: Fix compatible reservation handling (CRH=1) with legacy RESERVE/RELEASE

2012-03-19T16:02:36+00:00

commit 087a03b3ea1c8d6e2d5743a8d1c6d571058caa04 upstream.

This patch addresses a bug with target_check_scsi2_reservation_conflict()
return checking in target_scsi2_reservation_[reserve,release]() that was
preventing CRH=1 operation from silently succeeding in the two special
cases defined by SPC-3, and not failing with reservation conflict status
when dealing with legacy RESERVE/RELEASE + active SPC-3 PR logic.

Also explictly set cmd->scsi_status = SAM_STAT_RESERVATION_CONFLICT during
the early non reservation holder failure from pr_ops->t10_seq_non_holder()
check in transport_generic_cmd_sequencer() for fabrics that already expect
it to be set.

This bug was originally introduced in mainline commit:

iscsi-target: Fix reservation conflict -EBUSY response handling bug

2012-03-19T16:02:36+00:00

commit 00fdc6bbef77844ce397a7de7acfaf25e8e2e4eb upstream.

This patch addresses a iscsi-target specific bug related to reservation conflict
handling in iscsit_handle_scsi_cmd() that has been causing reservation conflicts
to complete and not fail as expected due to incorrect errno checking.  The problem
occured with the change to return -EBUSY from transport_generic_cmd_sequencer() ->
transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd()
checking for -EINVAL in order to invoke a non GOOD status response.

This was manifesting itself as data corruption with legacy SPC-2 reservations,
but also effects iscsi-target LUNs with SPC-3 persistent reservations.

This bug was originally introduced in lio-core commit:

i2c-algo-bit: Fix spurious SCL timeouts under heavy load

2012-03-19T16:02:35+00:00

commit 8ee161ce5e0cfc689eb677f227a6248191165fac upstream.

When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.

To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

rapidio/tsi721: fix bug in register offset definitions

2012-03-19T16:02:35+00:00

commit 9bbad7da76b3dd578fb55c862624366a8c9ccd22 upstream.

Fix indexed register offset definitions that use decimal (wrong) instead
of hexadecimal (correct) notation for indexing multipliers.

Incorrect definitions do not affect Tsi721 driver in its current default
configuration because it uses only IDB queue 0.  Loss of inbound
doorbell functionality should be observed if queue other than 0 is used.

comment right before that, and document the W83627UHG as reporting up
