Split SCSI header files
Move the constants that are used by both initiator and target drivers into the new header file <scsi/scsi_proto.h>. This change will allow to remove the initiator SCSI header include directives from most SCSI target source files in a later patch.

scsi: Do not set cmd_per_lun to 1 in the host template
'0' is now used as the default cmd_per_lun value, so there's no need to explicitly set it to '1' in the host template. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com> |

SCSI: add 1024 max sectors black list flag
This works around a issue with qnap iscsi targets not handling large IOs very well. The target returns: VPD INQUIRY: Block limits page (SBC) Maximum compare and write length: 1 blocks Optimal transfer length granularity: 1 blocks Maximum transfer length: 4294967295 blocks Optimal transfer length: 4294967295 blocks Maximum prefetch, xdread, xdwrite transfer length: 0 blocks Maximum unmap LBA count: 8388607 Maximum unmap block descriptor count: 1 Optimal unmap granularity: 16383 Unmap granularity alignment valid: 0 Unmap granularity alignment: 0 Maximum write same length: 0xffffffff blocks Maximum atomic transfer length: 0 Atomic alignment: 0 Atomic transfer length granularity: 0 and it is *sometimes* able to handle at least one IO of size up to 8 MB. We have seen in traces where it will sometimes work, but other times it looks like it fails and it looks like it returns failures if we send multiple large IOs sometimes. Also it looks like it can return 2 different errors. It will sometimes send iscsi reject errors indicating out of resources or it will send invalid cdb illegal requests check conditions. And then when it sends iscsi rejects it does not seem to handle retries when there are command sequence holes, so I could not just add code to try and gracefully handle that error code. The problem is that we do not have a good contact for the company, so we are not able to determine under what conditions it returns which error and why it sometimes works. So, this patch just adds a new black list flag to set targets like this to the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19 caused this regression, so I also ccing stable.

Merge git://git.infradead.org/intel-iommu
Pull intel iommu updates from David Woodhouse: "This lays a little of the groundwork for upcoming Shared Virtual Memory support — fixing some bogus #defines for capability bits and adding the new ones, and starting to use the new wider page tables where we can, in anticipation of actually filling in the new fields therein. It also allows graphics devices to be assigned to VM guests again. This got broken in 3.17 by disallowing assignment of RMRR-afflicted devices. Like USB, we do understand why there's an RMRR for graphics devices — and unlike USB, it's actually sane. So we can make an exception for graphics devices, just as we do USB controllers. Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty hack to allow broken BIOSes to forbid us from using X2APIC when they do stupid and invasive things and would break if we did. Someone noticed that since Windows doesn't have full IOMMU support for DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid initialising the IOMMU on the graphics unit altogether. This means that it would be available for use in "driver mode", where the IOMMU registers are made available through a BAR of the graphics device and the graphics driver can do SVM all for itself. So they started setting the X2APIC_OPT_OUT bit on *all* platforms with SVM capabilities. And even the platforms which *might*, if the planets had been aligned correctly, possibly have had SVM capability but which in practice actually don't" * git://git.infradead.org/intel-iommu: iommu/vt-d: support extended root and context entries iommu/vt-d: Add new extended capabilities from v2.3 VT-d specification iommu/vt-d: Allow RMRR on graphics devices too iommu/vt-d: Print x2apic opt out info instead of printing a warning iommu/vt-d: kill bogus ecap_niotlb_iunits() |

platform/chrome: Updates for v4.1
Here's a set of updates to the Chrome OS platform drivers for this merge window. Main new things this cycle is: - Driver changes to expose the lightbar to users. With this, you can make your own blinkenlights on Chromebook Pixels. - Changes in the way that the atmel_mxt trackpads are probed. The laptop driver is trying to be smart and not instantiate the devices that don't answer to probe. For the trackpad that can come up in two modes (bootloader or regular), this gets complicated since the driver already knows how to handle the two modes including the actual addresses used. So now the laptop driver needs to know more too, instantiating the regular address even if the bootloader one is the probe that passed. - mfd driver improvements by Javier Martines Canillas, and a few bugfixes from him, kbuild and myself. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJVOyVhAAoJEIwa5zzehBx3U/gP/jEqIMKEB6r0qApnYLU/0v2V 6AiAtQBDZ6PSNDOqy5Mo5HoMQ0WI09n4xvml3Ntmx0/584RGECn8nlFvwlowIxNo FLGYcKWuy8w8wKgN19hhEYySnTEex4+kBuDTITvya61SpvxUUfu7fpGV+DXwM2CS aJQdMOwl24BJ4gjev9JS5QasyZrAzZVuDwo8vSKG6PKZNGgC1uyjOrm+NjiTEW15 FzCk77rRHfiN6Zr9C79ZfqV/nWKm4rPvaJJOiNr2vZUQ/0bhbvSHp3/BekjtnlOv W6GbUCoDT6/DU/p1SP2Yegqk5pOEcqKQFe7Uc3YDSfiNLNCp03nF1RuIoi/NzfDy 1GcLYWAvHCrtmpQwqM/gIgc9uAsFN9Stin2G79xt3U/dUitdAmwMsCfqDE1FO63e pGjPx0H7e1Ot3en3O5agaAlYlsokptKl3bIVOMfK6s6bH3RK4Y83LxwsVQKYkayA TyulczOPnx6i4+acQroIwpFTj8QhhNjjhBU5gXTebVj4B/CwfieZBadaYF23O765 shX71oUJ1gQ6LCZtu8brl/82uk3sSkpVDi8e5WWaSnLfnAmqtU/ITy5yg77uuD0b RAdHxVFUO6Y0FspWmWzBckrPec7ub+SKglCACq8HNciGx/9BWx6NUWI9FK93CDIu O36D/l9hoUvA0gds5Iom =NVa4 -----END PGP SIGNATURE----- Merge tag 'chrome-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform Pull chrome platform updates from Olof Johansson: "Here's a set of updates to the Chrome OS platform drivers for this merge window.

direct-io: only inc/dec inode->i_dio_count for file systems
do_blockdev_direct_IO() increments and decrements the inode ->i_dio_count for each IO operation. It does this to protect against truncate of a file. Block devices don't need this sort of protection. For a capable multiqueue setup, this atomic int is the only shared state between applications accessing the device for O_DIRECT, and it presents a scaling wall for that. In my testing, as much as 30% of system time is spent incrementing and decrementing this value. A mixed read/write workload improved from ~2.5M IOPS to ~9.6M IOPS, with better latencies too. Before: clat percentiles (usec): | 1.00th=[ 33], 5.00th=[ 34], 10.00th=[ 34], 20.00th=[ 34], | 30.00th=[ 34], 40.00th=[ 34], 50.00th=[ 35], 60.00th=[ 35], | 70.00th=[ 35], 80.00th=[ 35], 90.00th=[ 37], 95.00th=[ 80], | 99.00th=[ 98], 99.50th=[ 151], 99.90th=[ 155], 99.95th=[ 155], | 99.99th=[ 165] After: clat percentiles (usec): | 1.00th=[ 95], 5.00th=[ 108], 10.00th=[ 129], 20.00th=[ 149], | 30.00th=[ 155], 40.00th=[ 161], 50.00th=[ 167], 60.00th=[ 171], | 70.00th=[ 177], 80.00th=[ 185], 90.00th=[ 201], 95.00th=[ 270], | 99.00th=[ 390], 99.50th=[ 398], 99.90th=[ 418], 99.95th=[ 422], | 99.99th=[ 438] In other setups, Robert Elliott reported seeing good performance improvements: https://lkml.org/lkml/2015/4/3/557 The more applications accessing the device, the worse it gets. Add a new direct-io flags, DIO_SKIP_DIO_COUNT, which tells do_blockdev_direct_IO() that it need not worry about incrementing or decrementing the inode i_dio_count for this caller.

md updates for 4.1
Highlights: - "experimental" code for managing md/raid1 across a cluster using DLM. Code is not ready for general use and triggers a WARNING if used. However it is looking good and mostly done and having in mainline will help co-ordinate development. - RAID5/6 can now batch multiple (4K wide) stripe_heads so as to handle a full (chunk wide) stripe as a single unit. - RAID6 can now perform read-modify-write cycles which should help performance on larger arrays: 6 or more devices. - RAID5/6 stripe cache now grows and shrinks dynamically. The value set is used as a minimum. - Resync is now allowed to go a little faster than the 'mininum' when there is competing IO. How much faster depends on the speed of the devices, so the effective minimum should scale with device speed to some extent. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIVAwUAVTbIxDnsnt1WYoG5AQIgAA//Z9FlEpkHcJJ75WGjrXgGJPyNTfEZOkoz jnD8PpBY2Afp341vMatd0XKErdEAhuPQmJMAa+tbxht6pk77X3fSzXghGA8FEafg yazn5pfBt6NXmepV4vhl/+LNYuWRxxLSA9EDm7wEg+tiO0UEts+a0w2TSXzcT1w+ 30Yi1EjAlTaJ5yjlBHUOtTXWE43D6RKnUr6FMy2dRlnzlFyDlezRMChWo9v6OkQF YqJ20FcvmJdLHY/6Yif3jvpm7eQecMqdCZENTvW/mJI86zqf6E+ToCYS1VNjfDnK ud61iU9eshu4WtNWBG6KLuHBD0grO1NaEL7/S16w1KdNJMhYgiK8WussvIAJEesA 5SlETM7Y/1XFq8puwlAq2/tuPfhZ+TFxnAwce/C3hMTDcYAACnS/R6INFQXqGvy3 nX1NLogrCycX8oqxv3jTFKLVqIVwlkSlHcUGzIWjcfCF37StcXFKI5q862agyg2+ NNocFMuXhPPM1YcB9JJSo2nCsor4e9tTdVEZlFm2B3cc8LJ9BLWUMSoi1h7VK/1g P7psnPIjz7/cdI2TZTFjGTZ0Kvhx/NTYp41AZealDNxeGWUNM+5xGZnUF8QRBc/E 0dGHtEAah834BDQFvNnJtuuh/s+KwbvswjNP+njoBsHjIQIvngDABpOwpIkdqF6r diQ2gUPnHN0= =OHG6 -----END PGP SIGNATURE----- Merge tag 'md/4.1' of git://neil.brown.name/md Pull md updates from Neil Brown: "More updates that usual this time.

This has been made possible by both changes to the ACPI spec to cater for ARM-based machines (known as "hardware-reduced" in ACPI parlance) but also a Linaro-driven effort to get this supported on top of the Linux kernel. This pull request is the result of that work. These changes allow us to initialise the CPUs, interrupt controller, and timers via ACPI tables, with memory information and cmdline coming from EFI. We don't support a hybrid ACPI/FDT scheme. Of course, there is still plenty of work to do (a serial console would be nice!) but I expect that to happen on a per-driver basis after this core series has been merged. Anyway, the diff stat here is fairly horrible, but splitting this up and merging it via all the different subsystems would have been extremely painful. Instead, we've got all the relevant Acks in place and I've not seen anything other than trivial (Kconfig) conflicts in -next (for completeness, I've included my resolution below).

sunrpc: make debugfs file creation failure non-fatal
v2: gracefully handle the case where some dentry pointers end up NULL and be more dilligent about zeroing out dentry pointers We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: "J.

Common MTD:
* Add Kconfig option for keeping both the 'master' and 'partition' MTDs registered as devices.

crush: straw2 bucket type with an efficient 64-bit crush_ln()
This is an improved straw bucket that correctly avoids any data movement between items A and B when neither A nor B's weights are changed. Said differently, if we adjust the weight of item C (including adding it anew or removing it completely), we will only see inputs move to or from C, never between other items in the bucket. Notably, there is not intermediate scaling factor that needs to be calculated. The mapping function is a simple function of the item weights. The below commits were squashed together into this one (mostly to avoid adding and then yanking a ~6000 lines worth of crush_ln_table): - crush: add a straw2 bucket type - crush: add crush_ln to calculate nature log efficently - crush: improve straw2 adjustment slightly - crush: change crush_ln to provide 32 more digits - crush: fix crush_get_bucket_item_weight and bucket destroy for straw2 - crush/mapper: fix divide-by-0 in straw2 (with div64_s64() for draw = ln / w and INT64_MIN -> S64_MIN - need to create a proper compat.h in ceph.git) Reflects ceph.git commits 242293c908e923d474910f2b8203fa3b41eb5a53, 32a1ead92efcd351822d22a5fc37d159c65c1338, 6289912418c4a3597a11778bcf29ed5415117ad9, 35fcb04e2945717cf5cfe150b9fa89cb3d2303a1, 6445d9ee7290938de1e4ee9563912a6ab6d8ee5f, b5921d55d16796e12d66ad2c4add7305f9ce2353.

md/raid5: activate raid6 rmw feature
Glue it altogehter. The raid6 rmw path should work the same as the already existing raid5 logic. So emulate the prexor handling/flags and split functions as needed. 1) Enable xor_syndrome() in the async layer. 2) Split ops_run_prexor() into RAID4/5 and RAID6 logic. Xor the syndrome at the start of a rmw run as we did it before for the single parity. 3) Take care of rmw run in ops_run_reconstruct6(). Again process only the changed pages to get syndrome back into sync. 4) Enhance set_syndrome_sources() to fill NULL pages if we are in a rmw run. The lower layers will calculate start & end pages from that and call the xor_syndrome() correspondingly. 5) Adapt the several places where we ignored Q handling up to now. Performance numbers for a single E5630 system with a mix of 10 7200k desktop/server disks. 300 seconds random write with 8 threads onto a 3,2TB (10*400GB) RAID6 64K chunk without spare (group_thread_cnt=4) bsize rmw_level=1 rmw_level=0 rmw_level=1 rmw_level=0 skip_copy=1 skip_copy=1 skip_copy=0 skip_copy=0 4K 115 KB/s 141 KB/s 165 KB/s 140 KB/s 8K 225 KB/s 275 KB/s 324 KB/s 274 KB/s 16K 434 KB/s 536 KB/s 640 KB/s 534 KB/s 32K 751 KB/s 1,051 KB/s 1,234 KB/s 1,045 KB/s 64K 1,339 KB/s 1,958 KB/s 2,282 KB/s 1,962 KB/s 128K 2,673 KB/s 3,862 KB/s 4,113 KB/s 3,898 KB/s 256K 7,685 KB/s 7,539 KB/s 7,557 KB/s 7,638 KB/s 512K 19,556 KB/s 19,558 KB/s 19,652 KB/s 19,688 Kb/s Signed-off-by: Markus Stockhausen <stockhausen@collogia.de> Signed-off-by: NeilBrown <neilb@suse.de> |

md/raid6 algorithms: delta syndrome functions
v3: s-o-b comment, explanation of performance and descision for the start/stop implementation Implementing rmw functionality for RAID6 requires optimized syndrome calculation. Up to now we can only generate a complete syndrome. The target P/Q pages are always overwritten. With this patch we provide a framework for inplace P/Q modification. In the first place simply fill those functions with NULL values. xor_syndrome() has two additional parameters: start & stop. These will indicate the first and last page that are changing during a rmw run. That makes it possible to avoid several unneccessary loops and speed up calculation. The caller needs to implement the following logic to make the functions work. 1) xor_syndrome(disks, start, stop, ...): "Remove" all data of source blocks inside P/Q between (and including) start and end. 2) modify any block with start <= block <= stop 3) xor_syndrome(disks, start, stop, ...): "Reinsert" all data of source blocks into P/Q between (and including) start and end. Pages between start and stop that won't be changed should be filled with a pointer to the kernel zero page. The reasons for not taking NULL pages are: 1) Algorithms cross the whole source data line by line. Thus avoid additional branches. 2) Having a NULL page avoids calculating the XOR P parity but still need calulation steps for the Q parity. Depending on the algorithm unrolling that might be only a difference of 2 instructions per loop. The benchmark numbers of the gen_syndrome() functions are displayed in the kernel log. Do the same for the xor_syndrome() functions. This will help to analyze performance problems and give an rough estimate how well the algorithm works. The choice of the fastest algorithm will still depend on the gen_syndrome() performance. With the start/stop page implementation the speed can vary a lot in real life. E.g. a change of page 0 & page 15 on a stripe will be harder to compute than the case where page 0 & page 1 are XOR candidates. To be not to enthusiatic about the expected speeds we will run a worse case test that simulates a change on the upper half of the stripe. So we do: 1) calculation of P/Q for the upper pages 2) continuation of Q for the lower (empty) pages Signed-off-by: Markus Stockhausen <stockhausen@collogia.de> Signed-off-by: NeilBrown <neilb@suse.de> |

TTY/Serial patches for 4.1-rc1
Here's the big tty/serial driver update for 4.1-rc1. It was delayed for a bit due to some questions surrounding some of the console command line parsing changes that are in here. There's still one tiny regression for people who were previously putting multiple console command lines and expecting them all to be ignored for some odd reason, but Peter is working on fixing that. If not, I'll send a revert for the offending patch, but I have faith that Peter can address it. Other than the console work here, there's the usual serial driver updates and changes, and a buch of 8250 reworks to try to make that driver easier to maintain over time, and have it support more devices in the future. All of these have been in linux-next for a while.

The changes to the common clock framework for 4.0 are mostly new clock
drivers and updates to existing ones for feature enhancements and bug fixes. There is more churn than usual in the framework core due to the change to introduce per-user unique struct clk pointers in 4.0. This caused several regressions to surface, some of which were sent as fixes to 4.0. New generic clock drivers were added for GPIO- and PWM-based clock controllers. Additionally the common clk-divider code recieved several fixes to the way it rounds rates. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJVNcIIAAoJEKI6nJvDJaTU3a8QAM+fjhDMY5xpI6VIbxZaA2aR VUofw9/rdAtP1UdwtlSKBvCqpwwqt/U7zlMWU9v+UvTjYdHIf9SIDQoJnd+uEtwL roz/kNeB7WOVyxwbTJ2B5fjvPSN+mq8Rm8ANDcL8ZOGxxtt2Mip1IWMAlx2XUnwG tYZhB7EfKzLHZRblOdn2Q4U/4T+KXOFTSO+Gb9o2J0I2sJLI0NRXhcl9Fcoo8KVz G0ACWa0F1WKsbqzBATnhtYiKkuC3BeiS2eMuTVTlkP+Gd6YQ2f1zWLeBfXEiPGZb q0p/qTrUFLHbRoJMMuWaUfaBxb8PeUfM6yllxrzvRxPJU25pbj8OW/O5ZAe9xP8G S17sQ2nhEoWZW9hqbuA39IcLGa6RjT+TD+z3kmXQ9ZvCVDN2Oqqb/4ZNViwAvQq7 t67EfV7hGXty3Q58tS4XE9hHfwY+9YqMDLNIS/ED+hP8rcxTmiLlAIyk+qbT3b0l Q+375Ar7iCgihPPHYxeM5Qe1+Vsfh4NjR9thdAbT245MB3f90ULb+GNP/izUDOgA c/Ot6pStVFEUxTol6RlcLb85PugzrkoBOF/8ZLySdMLhALjPwaFcQZ1sFdcKUKlE tt7sZKQgbbCfqYGS9K264uUfWbdmZh05zhtkH0xUjyQpyIcnrYQsSIIEEnlbYnPp 0D55nooSGROKeud+gyrx =2LMr -----END PGP SIGNATURE----- Merge tag 'clk-for-linus-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clock framework updates from Michael Turquette: "The changes to the common clock framework for 4.0 are mostly new clock drivers and updates to existing ones for feature enhancements and bug fixes.

KVM: PPC: Book3S HV: Add fast real-mode H_RANDOM implementation.
Some PowerNV systems include a hardware random-number generator. This HWRNG is present on POWER7+ and POWER8 chips and is capable of generating one 64-bit random number every microsecond. The random numbers are produced by sampling a set of 64 unstable high-frequency oscillators and are almost completely entropic. PAPR defines an H_RANDOM hypercall which guests can use to obtain one 64-bit random sample from the HWRNG. This adds a real-mode implementation of the H_RANDOM hypercall. This hypercall was implemented in real mode because the latency of reading the HWRNG is generally small compared to the latency of a guest exit and entry for all the threads in the same virtual core. Userspace can detect the presence of the HWRNG and the H_RANDOM implementation by querying the KVM_CAP_PPC_HWRNG capability. The H_RANDOM hypercall implementation will only be invoked when the guest does an H_RANDOM hypercall if userspace first enables the in-kernel H_RANDOM implementation using the KVM_CAP_PPC_ENABLE_HCALL capability.
