commit 96908589 upstream. Commit 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVP3502CP Hardware) implemented a workaround for a known issue with Texas Instruments' USB 3.0 redriver IC but it left a condition where any xHCI host would be taken out of reset if port was placed in compliance mode and there was no device connected to the port. That condition would trigger a fake connection to a non-existent device so that usbcore would trigger a warm reset of the port, thus taking the link out of reset. This has the side-effect of preventing any xHCI host connected to a Linux machine from starting and running the USB 3.0 Electrical Compliance Suite because the port will mysteriously taken out of compliance mode and, thus, xHCI won't step through the necessary compliance patterns for link validation. This patch fixes the issue by just adding a missing check for XHCI_COMP_MODE_QUIRK inside xhci_hub_report_usb3_link_state() when PORT_CAS isn't set. This patch should be backported to all kernels containing commit 71c731a2. Fixes: 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVP3502CP Hardware) Cc: Alexis R.

commit 7a98948f upstream. The vblank waits in intel_tv_detect_type() are timing out for some reason. This is a regression caused removing seemingly useless vblank waits from the modeset seqeuence in: commit 56ef52ca Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Thu May 8 19:23:15 2014 +0300 drm/i915: Kill vblank waits after pipe enable on gmch platforms So it turns out they weren't all entirely useless. Apparently the pipe has to go through one full frame before we enable the TV port. Add a vblank wait to intel_enable_tv() to make sure that happens. Another approach was attempted by placing the vblank wait just after enabling the port. The theory behind that attempt was that we need to let the port stay enabled for one full frame before disabling it again during load detection. But that didn't work, and we definitely must have the vblank wait before enabling the port. Cc: Alan Bartlett <ajb@elrepo.org> Tested-by:

commit c4d69da1 upstream. Running igt, I was encountering the invalid TLB bug on my 845g, despite that it was using the CS workaround. Examining the w/a buffer in the error state, showed that the copy from the user batch into the workaround itself was suffering from the invalid TLB bug (the first cacheline was broken with the first two words reversed). Time to try a fresh approach. This extends the workaround to write into each page of our scratch buffer in order to overflow the TLB and evict the invalid entries. This could be refined to only do so after we update the GTT, but for simplicity, we do it before each batch. I suspect this supersedes our current workaround, but for safety keep doing both. v2: The magic number shall be 2. This doesn't conclusively prove that it is the mythical TLB bug we've been trying to workaround for so long, that it requires touching a number of pages to prevent the corruption indicates to me that it is TLB related, but the corruption (the reversed cacheline) is more subtle than a TLB bug, where we would expect it to read the wrong page entirely. Oh well, it prevents a reliable hang for me and so probably for others as well. Signed-off-by:

commit 3d8afe30 upstream. The arm64 interrupt migration code on cpu offline calls irqchip.irq_set_affinity() with the argument force=true. Originally this argument had no effect because it was not used by any interrupt chip driver and there was no semantics defined. This changed with commit 01f8fa4f ("genirq: Allow forcing cpu affinity of interrupts") which made the force argument useful to route interrupts to not yet online cpus without checking the target cpu against the cpu online mask. The following commit ffde1de6 ("irqchip: gic: Support forced affinity setting") implemented this for the GIC interrupt controller. As a consequence the cpu offline irq migration fails if CPU0 is offlined, because CPU0 is still set in the affinity mask and the validation against cpu online mask is skipped to the force argument being true. The following first_cpu(mask) selection always selects CPU0 as the target. Commit 601c9421("arm64: use cpu_online_mask when using forced irq_set_affinity") intended to fix the above mentioned issue but introduced another issue where affinity can be migrated to a wrong CPU due to unconditional copy of cpu_online_mask. As with for arm, solve the issue by calling irq_set_affinity() with force=false from the CPU offline irq migration code so the GIC driver validates the affinity mask against CPU online mask and therefore removes CPU0 from the possible target candidates. Also revert the changes done in the commit 601c9421 as it's no longer needed. Tested on Juno platform. Fixes: 601c9421("arm64: use cpu_online_mask when using forced irq_set_affinity") Signed-off-by:

commit 61a734d3 upstream. Always freeze processes when suspending and thaw processes when resuming to prevent a race noticeable with HVM guests. This prevents a deadlock where the khubd kthread (which is designed to be freezable) acquires a usb device lock and then tries to allocate memory which requires the disk which hasn't been resumed yet. Meanwhile, the xenwatch thread deadlocks waiting for the usb device lock. Freezing processes fixes this because the khubd thread is only thawed after the xenwatch thread finishes resuming all the devices. Signed-off-by:

commit 049255f5 upstream. Sierra Wireless Direct IP devices using the 68A3 product ID can be configured for modes including a CDC ECM class function. The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist. Signed-off-by:

commit 85601b8d upstream. Commit 249751f2 ("usb: phy: twl4030-usb: poll for ID disconnect") added twl4030_id_workaround_work() to deal with lost interrupts after ID pin goes down. Looks like commit f1ddc24c ("usb: phy: twl4030-usb: remove *set_suspend* and *phy_init* ops") changed things around for the generic phy framework, and delayed work no longer got called except initially during boot. The PHY connect and disconnect interrupts for twl4030-usb are not working after disconnecting a USB-A cable from the board, and the deeper idle states for omap are blocked as the USB controller stays busy. The issue can be solved by calling delayed work from twl4030_usb_irq() when ID pin is down and the PHY is not asleep like we already do in twl4030_id_workaround_work(). But as both twl4030_usb_irq() and twl4030_id_workaround_work() already do pretty much the same thing, let's call twl4030_usb_irq() from twl4030_id_workaround_work() instead of adding some more duplicate code. We also must call sysfs_notify() only when we have an interrupt and not from the delayed work as notified by Grazvydas Ignotas <notasas@gmail.com>.

commit a07d3220 upstream. CIFS servers process nlink counts differently for files and directories. In cifs_rename() if we the request fails on the existing target, we try to remove it through cifs_unlink() but this is not what we want to do for directories. As the result the following sequence of commands mkdir {1,2}; mv -T 1 2; rmdir {1,2}; mkdir {1,2}; echo foo > 2/bar and XFS test generic/023 fail with -ENOENT error. That's why the second mkdir reuses the existing inode (target inode of the mv -T command) with S_DEAD flag. Fix this by checking whether the target is directory or not and calling cifs_rmdir() rather than cifs_unlink() for directories. Signed-off-by:

commit 849f5169 upstream. If pcpu_map_pages() fails midway, it unmaps the already mapped pages. Currently, it doesn't flush tlb after the partial unmapping. This may be okay in most cases as the established mapping hasn't been used at that point but it can go wrong and when it goes wrong it'd be extremely difficult to track down. Flush tlb after the partial unmapping. Signed-off-by:

commit f0d27965 upstream. When pcpu_alloc_pages() fails midway, pcpu_free_pages() is invoked to free what has already been allocated. The invocation is across the whole requested range and pcpu_free_pages() will try to free all non-NULL pages; unfortunately, this is incorrect as pcpu_get_pages_and_bitmap(), unlike what its comment suggests, doesn't clear the pages array and thus the array may have entries from the previous invocations making the partial failure path free incorrect pages. Fix it by open-coding the partial freeing of the already allocated pages. Signed-off-by:
