2010-08-07scsi: stop using q->prepare_flush_fnFUJITA Tomonori
scsi-ml builds flush requests via q->prepare_flush_fn(), however, builds discard requests via q->prep_rq_fn. Using two different mechnisms for the similar requests (building commands in SCSI ULD) doesn't make sense. Handing both via q->prep_rq_fn makes the code design simpler.

This fixes discard page leak by using q->unprep_rq_fn facility. q->unprep_rq_fn is called when all the data buffer (req->bio and scsi_data_buffer) in the request is freed. sd_unprep() uses rq->buffer to free discard page allocated in sd_prepare_discard().

2010-08-07block: don't allocate a payload for discard requestChristoph Hellwig
Allocating a fixed payload for discard requests always was a horrible hack, and it's not coming to byte us when adding support for discard in DM/MD. So change the code to leave the allocation of a payload to the lowlevel driver. Unfortunately that means we'll need another hack, which allows us to update the various block layer length fields indicating that we have a payload. Instead of hiding this in sd.c, which we already partially do for UNMAP support add a documented helper in the core block layer for it.

2010-08-07virtio_blk: add default case to cmd type switchJens Axboe
On compilation, gcc correctly detects that we do not handle all types: In function ‘blk_done’: warning: enumeration value ‘REQ_TYPE_FS’ not handled in switch warning: enumeration value ‘REQ_TYPE_SENSE’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SUSPEND’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_RESUME’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SHUTDOWN’ not handled in switch warning: enumeration value ‘REQ_TYPE_LINUX_BLOCK’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_TASKFILE’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_PC’ not handled in switch which is a bit pointless since this is at the end of the request processessing.

2010-08-07block: unify flags for struct bio and struct requestChristoph Hellwig
Remove the current bio flags and reuse the request flags for the bio, too. This allows to more easily trace the type of I/O from the filesystem down to the block driver. There were two flags in the bio that were missing in the requests: BIO_RW_UNPLUG and BIO_RW_AHEAD. Also I've renamed two request flags that had a superflous RW in them. Note that the flags are in bio.h despite having the REQ_ name - as blkdev.h includes bio.h that is the only way to go for now.

We can safely remove ISA_DMA_THRESHOLD usage in aha1542. aha1542 uses ISA_DMA_THRESHOLD to see if: - the buffers in scatter/list are below 16MB. - scsi_host is below 16MB.

2010-08-07cciss: add performant mode support for Stars/SiriusMike Miller
Add a mode of controller operation called Performant Mode. Even though cciss has been deprecated in favor of hpsa there are new controllers due out next year that HP must support in older vendor distros. Vendors require all fixes/features be upstream. These new controllers support only 16 commands in simple mode but support up to 1024 in performant mode. This requires us to add this support at this late date. The performant mode transport minimizes host PCI accesses by performinf many completions per read. PCI writes are posted so the host can write then immediately get off the bus not waiting for the writwe to complete to the target. In the context of performant mode the host read out to a controller pulls all posted writes into host memory ensuring the reply queue is coherent.

2010-08-07ACPI / ACPICA: Fix reference counting problems with GPE handlersRafael J. Wysocki
If a handler is installed for a GPE associated with an AML method and such that it cannot wake up the system from sleep states, the GPE remains enabled after the handler has been installed, although it should be disabled in that case to avoid spurious execution of the handler. Fix this issue by making acpi_install_gpe_handler() disable GPEs that were previously associated with AML methods and cannot wake up the system from sleep states. Analogously, make acpi_remove_gpe_handler() enable the GPEs that are associated with AML methods after their handlers have been removed and cannot wake up the system from sleep states. In addition to that, fix a code ordering issue in acpi_remove_gpe_handler() that renders the locking ineffective (ACPI_MTX_EVENTS is released temporarily in the middle of the routine to wait for the completion of events already in progress). For this purpose introduce acpi_raw_disable_gpe() and acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to use them. Also rework acpi_gpe_can_wake() to use acpi_raw_disable_gpe() instead of calling acpi_disable_gpe() after releasing the lock to avoid the possible theoretical race with acpi_install_gpe_handler().

2010-08-06pci: fix type warnings in intr_remapping.cLinus Torvalds
Commit 69309a059075 ("x86, asm: Clean up and simplify set_64bit()") sanitized the x86-64 types to set_64bit(), and incidentally resulted in warnings like drivers/pci/intr_remapping.c: In function 'modify_irte': drivers/pci/intr_remapping.c:314: warning: passing argument 1 of 'set_64bit' from incompatible pointer type arch/x86/include/asm/cmpxchg_64.h:6: note:expected 'volatile u64 *' but argument is of type 'long unsigned int *' It turns out that the change to set_64bit() really does clean up things, and the PCI intr_remapping.c file did a rather ugly cast in order to avoid warnings with the previous set_64bit() type model. Removing the ugly cast fixes the warning, and makes everybody happy and expects a set_64bit() to take the logical "u64 *" argument.

2010-08-06[SCSI] ibmvfc: Fix rport add/delete race resulting in oopsBrian King
Commit 43c8da907ccc656935d1085701f4db83385d8a59 introduced a race condition which can occur when adding/deleting rports. There are two possible threads now that can be deleting rports in the ibmvfc driver, which can result in list_del being called twice, resulting in an oops. This patch adds a new state to the ibmvfc_target struct to indicate the target has been removed from the list and is in the process of being deleted.
