2014-09-23parisc: Only use -mfast-indirect-calls option for 32-bit kernel buildsJohn David Anglin1-1/+6
In spite of what the GCC manual says, the -mfast-indirect-calls has never been supported in the 64-bit parisc compiler. Indirect calls have always been done using function descriptors irrespective of the -mfast-indirect-calls option. Recently, it was noticed that a function descriptor was always requested when the -mfast-indirect-calls option was specified. This caused problems when the option was used in application code and doesn't make any sense because the whole point of the option is to avoid using a function descriptor for indirect calls. Fixing this broke 64-bit kernel builds. I will fix GCC but for now we need the attached change. This results in the same kernel code as before.

2014-09-19USB: storage: Add quirks for Entrega/Xircom USB to SCSI convertersMark1-0/+20
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

2014-09-19USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapterMark1-0/+6
Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

2014-09-19USB: EHCI: unlink QHs even after the controller has stoppedAlan Stern1-2/+0
Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.

2014-09-18NFSv4: Fix another bug in the close/open_downgrade codeTrond Myklebust1-15/+15
James Drew reports another bug whereby the NFS client is now sending an OPEN_DOWNGRADE in a situation where it should really have sent a CLOSE: the client is opening the file for O_RDWR, but then trying to do a downgrade to O_RDONLY, which is not allowed by the NFSv4 spec. Reported-by: James Drews <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Fixes: aee7af356e15 (NFSv4: Fix problems with close in the presence...)

2014-09-18NFSv4: nfs4_state_manager() vs. nfs_server_remove_lists()Steve Dickson1-18/+20
There is a race between nfs4_state_manager() and nfs_server_remove_lists() that happens during a nfsv3 mount. The v3 mount notices there is already a supper block so nfs_server_remove_lists() called which uses the nfs_client_lock spin lock to synchronize access to the client list. At the same time nfs4_state_manager() is running through the client list looking for work to do, using the same lock. When nfs4_state_manager() wins the race to the list, a v3 client pointer is found and not ignored properly which causes the panic. Moving some protocol checks before the state checking avoids the panic.

2014-09-18Revert "Btrfs: device_list_add() should not update list when mounted"Chris Mason1-7/+6
This reverts commit b96de000bc8bc9688b3a2abea4332bd57648a49f. This commit is triggering failures to mount by subvolume id in some configurations. The main problem is how many different ways this scanning function is used, both for scanning while mounted and unmounted. A proper cleanup is too big for late rcs. For now, just revert the commit and we'll put a better fix into a later merge window. Signed-off-by: Chris Mason <[email protected]>
