Commit 8135cf8b092723dbfcc611fe6fdcb3a36c9951c5 (xen/pciback: Save xen_pci_op commands before processing it) broke enabling MSI-X because it would never copy the resulting vectors into the response. The number of vectors requested was being overwritten by the return value (typically zero for success). Save the number of vectors before processing the op, so the correct number of vectors are copied afterwards.

2016-02-15mmc: omap_hsmmc: Fix PM regression with deferred probe for pm_runtime_reinitTony Lindgren
Commit 5de85b9d57ab ("PM / runtime: Re-init runtime PM states at probe error and driver unbind") introduced pm_runtime_reinit() that is used to reinitialize PM runtime after -EPROBE_DEFER. This allows shutting down the device after a failed probe. However, for drivers using pm_runtime_use_autosuspend() this can cause a state where suspend callback is never called after -EPROBE_DEFER. On the following device driver probe, hardware state is different from the PM runtime state causing omap_device to produce the following error: omap_device_enable() called from invalid state 1 And with omap_device and omap hardware being picky for PM, this will block any deeper idle states in hardware. The solution is to fix the drivers to follow the PM runtime documentation: 1. For sections of code that needs the device disabled, use pm_runtime_put_sync_suspend() if pm_runtime_set_autosuspend() has been set. 2. For driver exit code, use pm_runtime_dont_use_autosuspend() before pm_runtime_put_sync() if pm_runtime_use_autosuspend() has been set.

2016-02-15iommu/vt-d: Clear PPR bit to ensure we get more page request interruptsDavid Woodhouse
According to the VT-d specification we need to clear the PPR bit in the Page Request Status register when handling page requests, or the hardware won't generate any more interrupts. This wasn't actually necessary on SKL/KBL (which may well be the subject of a hardware erratum, although it's harmless enough). But other implementations do appear to get it right, and we only ever get one interrupt unless we clear the PPR bit.

2016-02-15iwlwifi: pcie: fix RF-Kill vs. firmware load raceEmmanuel Grumbach
When we load the firmware, we hold trans_pcie->mutex to avoid nested flows. We also rely on the ISR to wake up the thread when the DMA has finished copying a chunk. During this flow, we enable the RF-Kill interrupt. The problem is that the RF-Kill interrupt handler can take the mutex and bring the device down. This means that if we load the firmware while the RF-Kill switch is enabled (which will happen when we load the INIT firmware to read the device's capabilities and register to mac80211), we may get an RF-Kill interrupt immediately and the ISR will be waiting for the mutex held by the thread that is currently loading the firmware. At this stage, the ISR won't be able to service the DMA's interrupt needed to wake up the thread that load the firmware. We are in a deadlock situation which ends when the thread that loads the firmware fails on timeout and releases the mutex. To fix this, take the mutex later in the flow, disable the interrupts and synchronize_irq() to give a chance to the RF-Kill interrupt to run and complete. After that, mask all the interrupts besides the DMA interrupt and proceed with firmware load. Make sure to check that there was no RF-Kill interrupt when the interrupts were disabled.

2016-02-15powerpc/mm: Fix Multi hit ERAT cause by recent THP updateAneesh Kumar K.V
With ppc64 we use the deposited pgtable_t to store the hash pte slot information. We should not withdraw the deposited pgtable_t without marking the pmd none. This ensure that low level hash fault handling will skip this huge pte and we will handle them at upper levels. Recent change to pmd splitting changed the above in order to handle the race between pmd split and exit_mmap. The race is explained below. Consider following race: CPU0 CPU1 shrink_page_list() add_to_swap() split_huge_page_to_list() __split_huge_pmd_locked() pmdp_huge_clear_flush_notify() // pmd_none() == true exit_mmap() unmap_vmas() zap_pmd_range() // no action on pmd since pmd_none() == true pmd_populate() As result the THP will not be freed. The leak is detected by check_mm(): BUG: Bad rss-counter state mm:ffff880058d2e580 idx:1 val:512 The above required us to not mark pmd none during a pmd split. The fix for ppc is to clear the huge pte of _PAGE_USER, so that low level fault handling code skip this pte. At higher level we do take ptl lock. That should serialze us against the pmd split. Once the lock is acquired we do check the pmd again using pmd_same. That should always return false for us and hence we should retry the access. We do the pmd_same check in all case after taking plt with THP (do_huge_pmd_wp_page, do_huge_pmd_numa_page and huge_pmd_set_accessed) Also make sure we wait for irq disable section in other cpus to finish before flipping a huge pte entry with a regular pmd entry. Code paths like find_linux_pte_or_hugepte depend on irq disable to get a stable pte_t pointer. A parallel thp split need to make sure we don't convert a pmd pte to a regular pmd entry without waiting for the irq disable section to finish.

2016-02-15powerpc/powernv: Fix stale PE primary busGavin Shan
When PCI bus is unplugged during full hotplug for EEH recovery, the platform PE instance (struct pnv_ioda_pe) isn't released and it dereferences the stale PCI bus that has been released. It leads to kernel crash when referring to the stale PCI bus. This fixes the issue by correcting the PE's primary bus when it's oneline at plugging time, in pnv_pci_dma_bus_setup() which is to be called by pcibios_fixup_bus().

2016-02-15powerpc/eeh: Fix stale cached primary busGavin Shan
When PE is created, its primary bus is cached to pe->bus. At later point, the cached primary bus is returned from eeh_pe_bus_get(). However, we could get stale cached primary bus and run into kernel crash in one case: full hotplug as part of fenced PHB error recovery releases all PCI busses under the PHB at unplugging time and recreate them at plugging time. pe->bus is still dereferencing the PCI bus that was released. This adds another PE flag (EEH_PE_PRI_BUS) to represent the validity of pe->bus. pe->bus is updated when its first child EEH device is online and the flag is set. Before unplugging in full hotplug for error recovery, the flag is cleared.

Update the mailing list used for development of support for ARM64 Renesas SoCs. This is a follow-up for a similar change for other Renesas SoCs and drivers uses by Renesas SoCs. The ARM64 SoC entry was not updated in that patch as it was not yet present in mainline. The motivation for the mailing list update is that Renesas SoCs are now much wider than the SH architecture and there is some desire from some for the linux-sh list to refocus on discussion of the work on the SH architecture.

2016-02-14usb: retry reset if a device times outOliver Neukum
Some devices I got show an inability to operate right after power on if they are already connected. They are beyond recovery if the descriptors are requested multiple times. So in case of a timeout we rather bail early and reset again. But it must be done only on the first loop lest we get into a reset/time out spiral that can be overcome with a retry.

2016-02-14USB: Add support for usbfs zerocopy.Steinar H. Gunderson
Add a new interface for userspace to preallocate memory that can be used with usbfs. This gives two primary benefits: - Zerocopy; data no longer needs to be copied between the userspace and the kernel, but can instead be read directly by the driver from userspace's buffers. This works for all kinds of transfers (even if nonsensical for control and interrupt transfers); isochronous also no longer need to memset() the buffer to zero to avoid leaking kernel data. - Once the buffers are allocated, USB transfers can no longer fail due to memory fragmentation; previously, long-running programs could run into problems finding a large enough contiguous memory chunk, especially on embedded systems or at high rates. Memory is allocated by using mmap() against the usbfs file descriptor, and similarly deallocated by munmap(). Once memory has been allocated, using it as pointers to a bulk or isochronous operation means you will automatically get zerocopy behavior. Note that this also means you cannot modify outgoing data until the transfer is complete. The same holds for data on the same cache lines as incoming data; DMA modifying them at the same time could lead to your changes being overwritten. There's a new capability USBDEVFS_CAP_MMAP that userspace can query to see if the running kernel supports this functionality, if just trying mmap() is not acceptable.

2016-02-14usb: host: ohci-pxa27x: propagate the irq error codeRobert Jarzmik
In several drivers in the pxa architecture, it was found that the platform_get_irq() was not propagated. This breaks the the device-tree probe deferral path, if -EPROBE_DEFER is returned. Unfortunately, the error return in this case is transformed into -ENXIO, breaking the deferral mechanism. Even if in this specific case the driver was not broken, because the interrupt controller is always probed before drivers, propagate the proper return code.

2016-02-14xhci: Support extended burst isoc TRB structure used by xhci 1.1 for USB 3.1Mathias Nyman
The transfer burst count (TBC) field in the Isoc TRB does not fit the new larger burst count available for USB 3.1 SSP Isoc tranfers. xhci 1.1 solved this by reusing the TD size field for transfer burst count. The Mult field was outgrown as well. xhci 1.1 controllers can calculate Mult itself and is not set if the new layout is used. xhci 1.1 controllers that support the new Isoc TRB format expose a Extended TBC Capability (ETC). To take the new format into use the xhci host controller driver needs to set a Extended TBC Enable (ETE) bit.

2016-02-14xhci: Add SuperSpeedPlus high bandwidth isoc support to xhci endpointsMathias Nyman
SuperSpeedPlus doubled the number of transactions per service interval the isoc endpoints supports. To support this, xhci 1.1 added Large ESIT Capability (LEC), which takes into use new bits in the endpoint context to fit the parameters. If xhci supports LEC, and the device has a SuperSpeedPlus Isoc companion descriptor then take into use the high bits of max esit payload, and skip calculating the Mult field as it wouldn't fit. LEC capable host will calculate the Mult based on other paramenters. Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

USB 3.1 devices can return a new SuperSpeedPlus isoc endpoint companion descriptor for a isochronous endpoint that requires more than 48K bytes per Service Interval. The new descriptor immediately follows the old USB 3.0 SuperSpeed Endpoint Companion and will provide a new BytesPerInterval value. It is parsed and stored in struct usb_host_endpoint with the other endpoint related descriptors, and should be used by USB3.1 capable hosts to reserve bus time in the schedule.

It contains number of bytes per service interval which is needed when reserving bus time in the schedule for transfers over 48K bytes per service interval.
