Tidy up and use cond_resched_rcu_qs when calling cond_resched and reporting potential quiescent state to RCU. Splitting this change in this way allows easy backporting to -stable for kernel versions not having cond_resched_rcu_qs().

Similar to the stop_machine deadlock scenario on !PREEMPT kernels addressed in b22ce278 "workqueue: cond_resched() after processing each work item", kworker threads requeueing back-to-back with zero jiffy delay can stall RCU. The cond_resched call introduced in that fix will yield only iff there are other higher priority tasks to run, so force a quiescent RCU state between work items.

Add a "rw_lock" torture test to stress kernel rwlocks and their irq variant. Reader critical regions are 5x longer than writers. As such a similar ratio of lock acquisitions is seen in the statistics. In the case of massive contention, both hold the lock for 1/10 of a second.

Pull workqueue fix from Tejun Heo: "create_singlethread_workqueue() is the old interface which is kept around for backward compatibility - each should be reviewed to determine whether singlethread usage was to save worker threads or for ordering guarantee and whether it's depended upon by memory reclaim path. While adding NUMA support for unbound workqueues during v3.10, I forgot to update it breaking the singlethread and ordering properties on NUMA setups. The breakage was unfortunately rather subtle and went without being reported until now. The only missing piece is __WQ_ORDERED flag which makes the unbounded workqueue use a single backend queue across different NUMA nodes. It's fixed by making create_singlethread_workqueue() wrap alloc_ordered_workqueue() so that possible future updates are inherited automatically" * 'for-3.17-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: apply __WQ_ORDERED to create_singlethread_workqueue()

On 32-bit architectures, the legacy buffer_head functions are not always handling the sector number with the proper 64-bit types, and will thus fail on 4TB+ disks. Any code that uses __getblk() (and thus bread(), breadahead(), sb_bread(), sb_breadahead(), sb_getblk()), and calls it using a 64-bit block on a 32-bit arch (where "long" is 32-bit) causes an inifinite loop in __getblk_slow() with an infinite stream of errors logged to dmesg like this: __find_get_block_slow() failed. block=6740375944, b_blocknr=2445408648 b_state=0x00000020, b_size=512 device sda1 blocksize: 512 Note how in hex block is 0x191C1F988 and b_blocknr is 0x91C1F988 i.e. the top 32-bits are missing (in this case the 0x1 at the top). This is because grow_dev_page() is broken and has a 32-bit overflow due to shifting the page index value (a pgoff_t - which is just 32 bits on 32-bit architectures) left-shifted as the block number. But the top bits to get lost as the pgoff_t is not type cast to sector_t / 64-bit before the shift. This patch fixes this issue by type casting "index" to sector_t before doing the left shift. Note this is not a theoretical bug but has been seen in the field on a 4TiB hard drive with logical sector size 512 bytes. This patch has been verified to fix the infinite loop problem on 3.17-rc5 kernel using a 4TB disk image mounted using "-o loop". Without this patch doing a "find /nt" where /nt is an NTFS volume causes the inifinite loop 100% reproducibly whilst with the patch it works fine as expected.

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?

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.

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.
