2009-04-28ide-cd: convert to using generic sense requestBorislav Petkov
Preallocate a sense request in the ->do_request method and reinitialize it only on demand, in case it's been consumed in the IRQ handler path. The reason for this is that we don't want to be mapping rq to bio in the IRQ path and introduce all kinds of unnecessary hacks to the block layer. tj: * Both user and kernel PC requests expect sense data to be stored in separate storage other than drive->sense_data. Copy sense data to rq->sense on completion if rq->sense is not NULL. This fixes bogus sense data on PC requests. As a result, remove cdrom_queue_request_sense.

2009-04-28ide: add helpers for preparing sense requestsBorislav Petkov
This is in preparation of removing the queueing of a sense request out of the IRQ handler path. Use struct request_sense as a general sense buffer for all ATAPI devices ide-{floppy,tape,cd}. tj: * blk_get_request(__GFP_WAIT) can't be called from do_request() as it can cause deadlock. Converted to use inline struct request and blk_rq_init(). * Added xfer / cdb len selection depending on device type. * All sense prep logics folded into ide_prep_sense() which never fails. * hwif->rq clearing and sense_rq used handling moved into ide_queue_sense_rq(). * blk_rq_map_kern() conversion is moved to later patch.

2009-04-28ide-cd: don't abuse rq->bufferTejun Heo
Impact: rq->buffer usage cleanup ide-cd uses rq->buffer to carry pointer to the original request when issuing REQUEST_SENSE. Use rq->special instead. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
2009-04-28ide-atapi: don't abuse rq->bufferTejun Heo
Impact: rq->buffer usage cleanup ide-atapi uses rq->buffer as private opaque value for internal special requests. rq->special isn't used for these cases (the only case where rq->special is used is for ide-tape rw requests). Use rq->special instead. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
2009-04-28ide-taskfile: don't abuse rq->bufferTejun Heo
Impact: rq->buffer usage cleanup ide_raw_taskfile() directly uses rq->buffer to carry pointer to the data buffer. This complicates both block interface and ide backend request handling. Use blk_rq_map_kern() instead and drop special handling for REQ_TYPE_ATA_TASKFILE from ide_map_sg(). Note that REQ_RW setting is moved upwards as blk_rq_map_kern() uses it to initialize bio rw flag.

2009-04-28ide-floppy: block pc always uses bioTejun Heo
Impact: remove unnecessary code path Block pc requests always use bio and rq->data is always NULL. No need to worry about !rq->bio cases in idefloppy_block_pc_cmd(). Note that ide-atapi uses ide_pio_bytes() for bio PIO transfer which handle sg fine. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
2009-04-28ide-cd: clear sense buffer before issuing request senseTejun Heo
Impact: code simplification ide_cd_request_sense_fixup() clears the tail of the sense buffer if the device didn't completely fill it. This patch makes cdrom_queue_request_sense() clear the sense buffer before issuing the command instead of clearing it afterwards. This simplifies code and eases future changes.

2009-04-28ide-tape: remove back-to-back REQUEST_SENSE detectionTejun Heo
Impact: fix an oops which always triggers ide_tape_issue_pc() assumed drive->pc isn't NULL on invocation when checking for back-to-back request sense issues but drive->pc can be NULL and even when it's not NULL, it's not safe to dereference it once the previous command is complete because pc could have been freed or was on stack. Kill back-to-back REQUEST_SENSE detection. Signed-off-by: Tejun Heo <tj@kernel.org>

2009-04-28hd: fix lockingTejun Heo
hd dance around local irq and HD_IRQ enable without achieving much. It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: Tejun Heo <tj@kernel.org>

2009-04-24umem: fix request_queue lock warningSage Weil
The umem driver issues two warnings on boot, due to blk_plug_device() and blk_remove_plug() being called without q->queue_lock held. Starting with e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock is NULL (though that apparently isn't otherwise a problem as the driver is using card->lock for everything). Although blk_init_queue() with take a request_fn_proc and spinlock_t*, there isn't a corresponding init helper that takes a make_request_fn. Setting queue_lock to &card->lock explicitly seems to work fine for me. The warning goes away and the device appears to behave.

2009-04-24ACPI, i915: Register ACPI video even when not modesettingMatthew Garrett
The ACPI video driver defers registration to the i915 driver if the system supports opregion-mediated backlight control. This registration was only being performed in the KMS case. Ensure it's done even if we don't have modesetting enabled. http://bugzilla.kernel.org/show_bug.cgi?id=13048 Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-04-24Revert "ACPICA: delete check for AML access to port 0x81-83"Len Brown
This reverts commit fdbdc7fc79c02ae4ede869d514179a2c65633d28. That temporary quick-fix is no longer necessary, as the previous patch, a65131e942e25c707a652fa4ec2cfcd8b63fec11, "I/O port protection: update for windows compatibility" should handle this issue for all ports, including this one.

2009-04-24I/O port protection: update for windows compatibility.Lin Ming
For windows compatibility, 1) On a port protection violation, simply ignore the request and do not return an exception (allow the control method to continue execution.) 2) If only part of the request overlaps a protected port, read/write the individual ports that are not protected. http://bugzilla.kernel.org/show_bug.cgi?id=13036 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-04-23sony-laptop: always try to unblock rfkill on loadMattia Dongili
This fixes an inconsistent behaviour when loading the driver with the switch on or off. In the former case you would also need to soft unblock the switch via the sysfs file entries to really disable rfkill, in the latter you wouldn't.

2009-04-23sony-laptop: fix bogus error message display on resumeMattia Dongili
sony_backlight_update_status returns 0 on success -1 on failure (i.e.: the return value from acpi_callsetfunc. The return value in the resume path was broken and thus always displaying a bogus warning about not being able to restore the brightness level.

2009-04-23ACPI: EC: Fix ACPI EC resume non-query interrupt messageAlmer S. Tigelaar
When resuming from standby (on a laptop) I see the following message in my kernel.log: "ACPI: EC: non-query interrupt received, switching to interrupt mode" This apparently prevented sony-laptop to properly restore the brightness level on resume. The cause: In drivers/acpi/ec.c the acpi_ec_suspend function clears the GPE mode bit, but this is not restored in acpi_ec_resume (the function below it). The patch below fixes this by properly restoring the GPE_MODE bit. Tested and confirmed to work. Signed-off-by: Almer S.
