commit 2d31ca3a upstream. Regular randconfig nightly testing has detected problems with omapdrm. omapdrm fails to build when the kernel is built to support 64-bit DMA addresses and/or 64-bit physical addresses due to an assumption about the width of these types. Use %pad to print DMA addresses, rather than %x or %Zx (which is even more wrong than %x). Avoid passing a uint32_t pointer into a function which expects dma_addr_t pointer. drivers/gpu/drm/omapdrm/omap_plane.c: In function 'omap_plane_pre_apply': drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_plane.o] Error 1 drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_get_paddr': drivers/gpu/drm/omapdrm/omap_gem.c:794:4: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_describe': drivers/gpu/drm/omapdrm/omap_gem.c:991:4: error: format '%Zx' expects argument of type 'size_t', but argument 7 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_init': drivers/gpu/drm/omapdrm/omap_gem.c:1470:4: error: format '%x' expects argument of type 'unsigned int', but argument 7 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_gem.o] Error 1 drivers/gpu/drm/omapdrm/omap_dmm_tiler.c: In function 'dmm_txn_append': drivers/gpu/drm/omapdrm/omap_dmm_tiler.c:226:2: error: passing argument 3 of 'alloc_dma' from incompatible pointer type [-Werror] make[5]: *** [drivers/gpu/drm/omapdrm/omap_dmm_tiler.o] Error 1 make[5]: Target `__build' not remade because of errors. make[4]: *** [drivers/gpu/drm/omapdrm] Error 2 Signed-off-by:

commit 7f0b1bf0 upstream. The architecture specification states that both DSB and ISB are required between page table modifications and subsequent memory accesses using the corresponding virtual address. When TLB invalidation takes place, the tlb_flush_* functions already have the necessary barriers. However, there are other functions like create_mapping() for which this is not the case. The patch adds the DSB+ISB instructions in the set_pte() function for valid kernel mappings. The invalid pte case is handled by tlb_flush_* and the user mappings in general have a corresponding update_mmu_cache() call containing a DSB. Even when update_mmu_cache() isn't called, the kernel can still cope with an unlikely spurious page fault by re-executing the instruction. In addition, the set_pmd, set_pud() functions gain an ISB for architecture compliance when block mappings are created. Signed-off-by:

commit d8d28c8f upstream. The scheduler uses policy == -1 to preserve the current policy state to implement sched_setparam(). But, as (int) -1 is equals to 0xffffffff, it's matching the if (policy & SCHED_RESET_ON_FORK) on _sched_setscheduler(). This match changes the policy value to an invalid value, breaking the sched_setparam() syscall. This patch checks policy == -1 before check the SCHED_RESET_ON_FORK flag. The following program shows the bug: int main(void) { struct sched_param param = { .sched_priority = 5, }; sched_setscheduler(0, SCHED_FIFO, ¶m); param.sched_priority = 1; sched_setparam(0, ¶m); param.sched_priority = 0; sched_getparam(0, ¶m); if (param.sched_priority != 1) printf("failed priority setting (found %d instead of 1)\n", param.sched_priority); else printf("priority setting fine\n"); } Signed-off-by:

commit 8f873c1f upstream. Streams on the EJ168 do not work as they should. I've spend 2 days trying to get them to work, but without success. The first problem is that when ever you ring the stream-ring doorbell, the controller starts executing trbs at the beginning of the first ring segment, event if it ended somewhere else previously. This can be worked around by allowing enqueing only one td (not a problem with how streams are typically used) and then resetting our copies of the enqueueing en dequeueing pointers on a td completion to match what the controller seems to be doing. This way things seem to start working with uas and instead of being able to complete only the very first scsi command, the scsi core can probe the disk. But then things break later on when td-s get enqueued with more then one trb. The controller does seem to increase its dequeue pointer while executing a stream-ring (data transfer events I inserted for debugging do trigger). However execution seems to stop at the final normal trb of a multi trb td, even if there is a data transfer event inserted after the final trb. The first problem alone is a serious deviation from the spec, and esp. dealing with cancellation would have been very tricky if not outright impossible, but the second problem simply is a deal breaker altogether, so this patch simply disables streams. Note this will cause the usb-storage + uas driver pair to automatically switch to using usb-storage instead of uas on these devices, essentially reverting to the 3.14 and earlier behavior when uas was marked CONFIG_BROKEN. https://bugzilla.redhat.com/show_bug.cgi?id=1121288 https://bugzilla.kernel.org/show_bug.cgi?id=80101Signed-off-by:

commit d5d83f8a upstream. Calling pm_schedule_suspend from the runtime pm idle callback may reschedule existing timer, thus in case of frequent runtime rpm idle call the suspend maybe starved. Instead we call pm_runtime_autosuspend which is checking if the timer is already charged. An example is monitoring device pci config space. Pci config sysfs handlers calls pci_config_pm_runtime_put/get helpers which in turns calls to device idle callback Signed-off-by:

commit f3ee07d8 upstream. ALC269 & co have many vendor-specific setups with COEF verbs. However, some verbs seem specific to some codec versions and they result in the codec stalling. Typically, such a case can be avoided by checking the return value from reading a COEF. If the return value is -1, it implies that the COEF is invalid, thus it shouldn't be written. This patch adds the invalid COEF checks in appropriate places accessing ALC269 and its variants. The patch actually fixes the resume problem on Acer AO725 laptop.

commit f475371a upstream. On some HP laptops, the mute led is controlled by codec gpio. When some machine resume from s3/s4, the codec gpio data will be cleared to 0 by BIOS: Before suspend: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0 After resume: IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0 To skip the AFG node to enter D3 can't fix this problem. A workaround is to restore the gpio data when the system resume back from s3/s4. It is safe even on the machines without this problem. BugLink: https://bugs.launchpad.net/bugs/1358116Tested-by:

commit e24aa0a4 upstream. CA0132 driver tries to reload the firmware at resume. Usually this works since the firmware loader core caches the firmware contents by itself. However, if the driver failed to load the firmwares (e.g. missing files), reloading the firmware at resume goes through the actual file loading code path, and triggers a kernel WARNING like: WARNING: CPU: 10 PID:11371 at drivers/base/firmware_class.c:1105 _request_firmware+0x9ab/0x9d0() For avoiding this situation, this patch makes CA0132 skipping the f/w loading at resume when it failed at probe time.

commit a40178b2 upstream. Problem Summary: Problem has been observed generally with PM states where VBUS goes off during suspend. There are some SS USB devices which take longer time for link training compared to many others. Such devices fail to reconnect with same old address which was associated with it before suspend. When system resumes, at some point of time (dpm_run_callback-> usb_dev_resume->usb_resume->usb_resume_both->usb_resume_device-> usb_port_resume) SW reads hub status. If device is present, then it finishes port resume and re-enumerates device with same address. If device is not present then, SW thinks that device was removed during suspend and therefore does logical disconnection and removes all the resource allocated for this device. Now, if I put sufficient delay just before root hub status read in usb_resume_device then, SW sees always that device is present. In normal course(without any delay) SW sees that no device is present and then SW removes all resource associated with the device at this port. In the latter case, after sometime, device says that hey I am here, now host enumerates it, but with new address. Problem had been reproduced when I connect verbatim USB3.0 hard disc with my STiH407 XHCI host running with 3.10 kernel. I see that similar problem has been reported here. https://bugzilla.kernel.org/show_bug.cgi?id=53211 Reading above it seems that bug was not in 3.6.6 and was present in 3.8 and again it was not present for some in 3.12.6, while it was present for few others. I tested with 3.13-FC19 running at i686 desktop, problem was still there. However, I was failed to reproduce it with 3.16-RC4 running at same i686 machine. I would say it is just a random observation. Problem for few devices is always there, as I am unable to find a proper fix for the issue. So, now question is what should be the amount of delay so that host is always able to recognize suspended device after resume. XHCI specs 4.19.4 says that when Link training is successful, port sets CSC bit to 1. So if SW reads port status before successful link training, then it will not find device to be present. USB Analyzer log with such buggy devices show that in some cases device switch on the RX termination after long delay of host enabling the VBUS. In few other cases it has been seen that device fails to negotiate link training in first attempt. It has been reported till now that few devices take as long as 2000 ms to train the link after host enabling its VBUS and RX termination. This patch implements a 2000 ms timeout for CSC bit to set ie for link training. If in a case link trains before timeout, loop will exit earlier. This patch implements above delay, but only for SS device and when persist is enabled. So, for the good device overhead is almost none. While for the bad devices penalty could be the time which it take for link training. But, If a device was connected before suspend, and was removed while system was asleep, then the penalty would be the timeout ie 2000 ms. Results: Verbatim USB SS hard disk connected with STiH407 USB host running 3.10 Kernel resumes in 461 msecs without this patch, but hard disk is assigned a new device address. Same system resumes in 790 msecs with this patch, but with old device address. Signed-off-by:

commit 6e693739 upstream. The EHCI packet buffer in/out threshold is programmable for Intel Quark X1000 USB host controller, and the default value is 0x20 dwords. The in/out threshold can be programmed to 0x80 dwords (512 Bytes) to maximize the perfomrance, but only when isochronous/interrupt transactions are not initiated by the USB host controller. This patch is to reconfigure the packet buffer in/out threshold as maximal as possible to maximize the performance, and 0x7F dwords (508 Bytes) should be used because the USB host controller initiates isochronous/interrupt transactions.

commit 977dcfdc upstream. This patch fixes a bug in ohci-hcd. When an URB is unlinked, the corresponding Endpoint Descriptor is added to the ed_rm_list and taken off the hardware schedule. Once the ED is no longer visible to the hardware, finish_unlinks() handles the URBs that were unlinked or have completed. If any URBs remain attached to the ED, the ED is added back to the hardware schedule -- but only if the controller is running. This fails when a controller dies. A non-empty ED does not get added back to the hardware schedule and does not remain on the ed_rm_list; ohci-hcd loses track of it. The remaining URBs cannot be unlinked, which causes the USB stack to hang. The patch changes finish_unlinks() so that non-empty EDs remain on the ed_rm_list if the controller isn't running. This requires moving some of the existing code around, to avoid modifying the ED's hardware fields more than once. Signed-off-by:

commit 410dd3cf upstream. We did not check relocated directory in any way when processing Rock Ridge 'CL' tag. Thus a corrupted isofs image can possibly have a CL entry pointing to another CL entry leading to possibly unbounded recursion in kernel code and thus stack overflow or deadlocks (if there is a loop created from CL entries). Fix the problem by not allowing CL entry to point to a directory entry with CL entry (such use makes no good sense anyway) and by checking whether CL entry doesn't point to itself. Reported-by:
