2008-12-29V4L/DVB (9361): Dynamic DVB minor allocationAndreas Oberritter
Implement dynamic minor allocation for DVB, to allow more than four devices of the same type per adapter, based on drivers/usb/core/file.c. Add a new config option, DVB_DYNAMIC_MINORS, to make use of this feature, which defaults to no for backwards compatibility.

2008-12-29ide: rework handling of serialized ports (v2)Bartlomiej Zolnierkiewicz
* hpt366: set IDE_HFLAG_SERIALIZE in ->host_flags if needed in init_hwif_hpt366(). Remove HPT_SERIALIZE_IO while at it. * Set IDE_HFLAG_SERIALIZE in ->host_flags if needed in ide_init_port(). * Convert init_irq() to use IDE_HFLAG_SERIALIZE together with hwif->host to find out ports which need to be serialized. * Remove no longer needed save_match() and ide_hwif_t.serialized. v2: * Set host's ->host_flags field instead of port's copy. This patch should fix the incorrect grouping of port(s) from host(s) that need serialization with port(s) that happen to use the same IRQ(s) but are from the host(s) that don't need it.

2008-12-29gayle: set IDE_HFLAG_SERIALIZE explictlyBartlomiej Zolnierkiewicz
If IDE doubler is used ports need to be serialized. Currently init_irq() handles it fine but lets also set IDE_HFLAG_SERIALIZE host flag explicitly in preparation for future changes.

2008-12-29ide: replace the global ide_lock spinlock by per-hwgroup spinlocks (v2)Bartlomiej Zolnierkiewicz
Now that (almost) all host drivers have been fixed not to abuse ide_lock and core code usage of ide_lock has been sanitized we may safely replace ide_lock by per-hwgroup locks. This patch is partially based on earlier patch from Ravikiran G Thirumalai. While at it: - don't use deprecated HWIF() and HWGROUP() macros - update locking documentation in ide.h v2: Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns) Cc: Vaibhav V.

2008-12-29ide: fix IDE ACPI regression breaking suspendBartlomiej Zolnierkiewicz
Commit 4dde4492d850a4c9bcaa92e5bd7f4eebe3e2f5ab ("ide: make drive->id an union (take 2)") accidentally introduced an IDE ACPI regression which at least on some machines confuses ACPI and breaks suspend. Fix it. Fixes kernel.org bug #12279: http://bugzilla.kernel.org/show_bug.cgi?id=12279 [ Sorry about the bug (IDE ACPI is not used by default so it managed to slip in). Still it is kind of surprising that the bug breaks suspend as it shouldn't impact anything except IDE ACPI (it seems that it uncovered either some ACPI/PM deficiency or a BIOS bug). ] Reported-and-bisected-by: David Roka <roka@dawid.hu> Tested-by: David Roka <roka@dawid.hu> Cc: Rafael J.

2008-12-29[SCSI] zfcp: Remove unnecessary warning messageChristof Schmitt
Remove a message that was emitted for a port that could not initially be opened. This is a rare case when the port discovery hits an initiator port and only confuses the user with an initator port logged in the message. Remove the whole special case: The failed "open port" request triggers required follow-up actions anyway.

2008-12-29[SCSI] zfcp: Add support for unchained FSF requestsChristof Schmitt
Add the support to send CT and ELS requests as unchained FSF requests. This is required for older hardware and was somehow omitted during the cleanup of the FSF layer. The req_count and resp_count attributes are unused, so remove them instead of adding a special case for setting them. Also add debug data and a warning, when the ct request hits a limit.

2008-12-29[SCSI] zfcp: remove DID_DID flagChristof Schmitt
The port flag DID_DID indicates whether we know the current id of the port. This is always set in parallel. Since the id 0 is invalid (because the port id 0 is invalid) we can remove the DID_DID flag: d_id of 0 indicates an invalid d_id != 0 is a valid one.
