[ Upstream commit 0ca33b4a ] Commit 1140011e ("mmc: sdhci-pxav3: Modify clock settings for the SDR50 and DDR50 modes") broke any chance of the SDR50 or DDR50 modes being used. The commit claims that SDR50 and DDR50 require clock adjustments in the SDIO3 Configuration register, which is located via the "conf-sdio3" resource. However, when this resource is given, we fail to read the host capabilities 1 register, resulting in host->caps1 being zero. Hence, both SDHCI_SUPPORT_SDR50 and SDHCI_SUPPORT_DDR50 bits remain zero, disabling the SDR50 and DDR50 modes. The underlying idea in this function appears to be to read the device capabilities, modify them, and set SDHCI_QUIRK_MISSING_CAPS to cause our modified capabilities to be used. Implement exactly that. Fixes: 1140011e ("mmc: sdhci-pxav3: Modify clock settings for the SDR50 and DDR50 modes") Signed-off-by:

[ Upstream commit b84106b4 ] The PCI config header (first 64 bytes of each device's config space) is defined by the PCI spec so generic software can identify the device and manage its usage of I/O, memory, and IRQ resources. Some non-spec-compliant devices put registers other than BARs where the BARs should be. When the PCI core sizes these "BARs", the reads and writes it does may have unwanted side effects, and the "BAR" may appear to describe non-sensical address space. Add a flag bit to mark non-compliant devices so we don't touch their BARs. Turn off IO/MEM decoding to prevent the devices from consuming address space, since we can't read the BARs to find out what that address space would be. Signed-off-by:

[ Upstream commit d0751b98 ] A PCIe Port is an interface to a Link. A Root Port is a PCI-PCI bridge in a Root Complex and has a Link on its secondary (downstream) side. For other Ports, the Link may be on either the upstream (closer to the Root Complex) or downstream side of the Port. The usual topology has a Root Port connected to an Upstream Port. We previously assumed this was the only possible topology, and that a Downstream Port's Link was always on its downstream side, like this: +---------------------+ +------+ | Downstream | | Root | | Upstream Port +--Link-- | Port +--Link--+ Port | +------+ | Downstream | | Port +--Link-- +---------------------+ But systems do exist (see URL below) where the Root Port is connected to a Downstream Port. In this case, a Downstream Port's Link may be on either the upstream or downstream side: +---------------------+ +------+ | Upstream | | Root | | Downstream Port +--Link-- | Port +--Link--+ Port | +------+ | Downstream | | Port +--Link-- +---------------------+ We can't use the Port type to determine which side the Link is on, so add a bit in struct pci_dev to keep track. A Root Port's Link is always on the Port's secondary side. A component (Endpoint or Port) on the other end of the Link obviously has the Link on its upstream side. If that component is a Port, it is part of a Switch or a Bridge. A Bridge has a PCI or PCI-X bus on its secondary side, not a Link. The internal bus of a Switch connects the Port to another Port whose Link is on the downstream side.

[ Upstream commit 3f4ce057 ] The driver utilizes an array of atomic variables to keep track of IO submissions to each vector. To submit an IO multiple threads iterate through the array to find a vector which has empty slots to send an IO. The reading and updating of the variable is not atomic, causing race conditions when a thread uses a full vector to submit an IO. Fixed by mapping each FIB to a vector, the submission path then uses said vector to submit IO thereby removing the possibly of a race condition.The vector assignment is started from 1 since vector 0 is reserved for the use of AIF management FIBS.If the number of MSIx vectors is 1 (MSI or INTx mode) then all the fibs are allocated to vector 0.

[ Upstream commit 6acfe68b ] Request-based DM's blk-mq support (dm-mq) was reported to be 50% slower than if an underlying null_blk device were used directly. One of the reasons for this drop in performance is that blk_insert_clone_request() was calling blk_mq_insert_request() with @async=true. This forced the use of kblockd_schedule_delayed_work_on() to run the blk-mq hw queues which ushered in ping-ponging between process context (fio in this case) and kblockd's kworker to submit the cloned request. The ftrace function_graph tracer showed: kworker-2013 => fio-12190 fio-12190 => kworker-2013 ... kworker-2013 => fio-12190 fio-12190 => kworker-2013 ... Fixing blk_insert_clone_request()'s blk_mq_insert_request() call to _not_ use kblockd to submit the cloned requests isn't enough to eliminate the observed context switches. In addition to this dm-mq specific blk-core fix, there are 2 DM core fixes to dm-mq that (when paired with the blk-core fix) completely eliminate the observed context switching: 1) don't blk_mq_run_hw_queues in blk-mq request completion Motivated by desire to reduce overhead of dm-mq, punting to kblockd just increases context switches. In my testing against a really fast null_blk device there was no benefit to running blk_mq_run_hw_queues() on completion (and no other blk-mq driver does this). So hopefully this change doesn't induce the need for yet another revert like commit 621739b0 ! 2) use blk_mq_complete_request() in dm_complete_request() blk_complete_request() doesn't offer the traditional q->mq_ops vs .request_fn branching pattern that other historic block interfaces do (e.g. blk_get_request). Using blk_mq_complete_request() for blk-mq requests is important for performance. It should be noted that, like blk_complete_request(), blk_mq_complete_request() doesn't natively handle partial completions -- but the request-based DM-multipath target does provide the required partial completion support by dm.c:end_clone_bio() triggering requeueing of the request via dm-mpath.c:multipath_end_io()'s return of DM_ENDIO_REQUEUE. dm-mq fix #2 is _much_ more important than #1 for eliminating the context switches. Before: cpu : usr=15.10%, sys=59.39%, ctx=7905181, majf=0, minf=475 After: cpu : usr=20.60%, sys=79.35%, ctx=2008, majf=0, minf=472 With these changes multithreaded async read IOPs improved from ~950K to ~1350K for this dm-mq stacked on null_blk test-case. The raw read IOPs of the underlying null_blk device for the same workload is ~1950K. Fixes: 7fb4898e ("block: add blk-mq support to blk_insert_cloned_request()") Fixes: bfebd1cd ("dm: add full blk-mq support to request-based DM") Cc: stable@vger.kernel.org # 4.1+ Reported-by:

commit b7a58459 upstream. On Xen PV, regs->flags doesn't reliably reflect IOPL and the exit-to-userspace code doesn't change IOPL. We need to context switch it manually. I'm doing this without going through paravirt because this is specific to Xen PV. After the dust settles, we can merge this with the 32-bit code, tidy up the iopl syscall implementation, and remove the set_iopl pvop entirely. Fixes XSA-171. Reviewewd-by:

[ Upstream commit fa52bd50 ] The usbvision driver crashes when a specially crafted usb device with invalid number of interfaces or endpoints is detected. This fix adds checks that the device has proper configuration expected by the driver. Reported-by:

[ Upstream commit 8a5e5e02 ] Poison pointer values should be small enough to find a room in non-mmap'able/hardly-mmap'able space. E.g. on x86 "poison pointer space" is located starting from 0x0. Given unprivileged users cannot mmap anything below mmap_min_addr, it should be safe to use poison pointers lower than mmap_min_addr. The current poison pointer values of LIST_POISON{1,2} might be too big for mmap_min_addr values equal or less than 1 MB (common case, e.g. Ubuntu uses only 0x10000). There is little point to use such a big value given the "poison pointer space" below 1 MB is not yet exhausted. Changing it to a smaller value solves the problem for small mmap_min_addr setups. The values are suggested by Solar Designer: http://www.openwall.com/lists/oss-security/2015/05/02/6Signed-off-by:
