2018-07-30s390/mm: Add huge page gmap linking supportJanosch Frank
Let's allow huge pmd linking when enabled through the KVM_CAP_S390_HPAGE_1M capability. Also we can now restrict gmap invalidation and notification to the cases where the capability has been activated and save some cycles when that's not the case.

2018-07-30s390/mm: hugetlb pages within a gmap can not be freedDominik Dingel
Guests backed by huge pages could theoretically free unused pages via the diagnose 10 instruction. We currently don't allow that, so we don't have to refault it once it's needed again.

2018-07-30media: em28xx: disable null packet filter for WinTVdualHDRobert Schlabbach
This patch disables the null packet filter for the Hauppauge WinTV-dualHD. There are applications which require the unfiltered transport stream (e.g. DOCSIS segment load analyzers). Tests showed that the device is capable of delivering two unfiltered EuroDOCSIS 3.0 transport streams simultaneously, i.e. over 100 Mbit/s worth of data, without any losses.

2018-07-30media: ddbridge/mci: split MaxSX8 specific code off to ddbridge-sx8.cDaniel Scheller
Split off all code specific to the MaxSX8 cards to a separate ddbridge-sx8 module and hook it up in the Makefile. This also adds evaluation of the mci_type to allow for using different attach handling for different cards. As different cards can implement things differently (ie. support differing frontend_ops, and have different base structs being put ontop of the common mci_base struct), this introduces the mci_cfg struct which is initially used to hold a few specifics to the -sx8 submodule. While at it, the handling of the i/q mode is adjusted slightly. Besides this and handling mci_base and sx8_base struct pointers where needed, all code is copied unmodified from ddbridge-mci.c.

In preparation for splitting all MaxSX8 related code parts from the common MCI code, prefix both mci_cmd() and mci_config() functions with ddb_, remove the static marking and add matching function prototypes to ddbridge-mci.h so these functions can be reused from other files within the ddbridge driver. As this requires the mci-related structs to be defined in ddbridge-mci.h, move struct mci and struct mci_base there and clean them up. Picked up from the upstream dddvb GIT.

2018-07-30media: ddbridge: probe for LNBH25 chips before attachingDaniel Scheller
In demod_attach_stv0910(), the LNBH25 IC is being blindly attached and, if the result is bad, blindly attached on another possible I2C address. The LNBH25 uses it's set_voltage function to test for the IC and will print an error to the kernel log on failure. Prevent this by probing the possible I2C address and use this (and only this) to attach the LNBH25 I2C driver. This also allows the stv0910 attach function to be a bit cleaner.

2018-07-30debugobjects: Make stack check warning more informativeJoel Fernandes (Google)
While debugging an issue debugobject tracking warned about an annotation issue of an object on stack. It turned out that the issue was due to the object in concern being on a different stack which was due to another issue. Thomas suggested to print the pointers and the location of the stack for the currently running task. This helped to figure out that the object was on the wrong stack. As this is general useful information for debugging similar issues, make the error message more informative by printing the pointers.

2018-07-30hv_netvsc: Add per-cpu ethtool stats for netvscYidong Ren
This patch implements following ethtool stats fields for netvsc: cpu<n>_tx/rx_packets/bytes cpu<n>_vf_tx/rx_packets/bytes Corresponding per-cpu counters already exist in current code. Exposing these counters will help troubleshooting performance issues. for_each_present_cpu() was used instead of for_each_possible_cpu(). for_each_possible_cpu() would create very long and useless output. It is still being used for internal buffer, but not for ethtool output. There could be an overflow if cpu was added between ethtool call netvsc_get_sset_count() and netvsc_get_ethtool_stats() and netvsc_get_strings(). (still safe if cpu was removed) ethtool makes these three function calls separately. As long as we use ethtool, I can't see any clean solution. Currently and in foreseeable short term, Hyper-V doesn't support cpu hot-plug. Plus, ethtool is for admin use. Unlikely the admin would perform such combo operations. Changes in v2: - Remove cpp style comment - Resubmit after freeze Changes in v3: - Reimplemented with kvmalloc instead of alloc_percpu Changes in v4: - Fixed inconsistent array size - Use kvmalloc_array instead of kvmalloc Signed-off-by: Yidong Ren <yidren@microsoft.com> Reviewed-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S.

2018-07-30ath10k: add debugfs file warm_hw_resetMaharaja Kennadyrajan
Debugfs support to do hardware warm reset with WMI command WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi service is enabled in the firmware for backward compatibility). This change is purely for debugging purpose when hardware hangs/mutes. This hardware reset won't affect the connectivity but there will be small pause in data traffic. Here we are doing BB/MAC level reset and hence whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset. So the target will be in the active state. Below command used to warm reset the hardware. echo 1 > /sys/kernel/debug/ieee80211/phyX/ath10k/warm_hw_reset Tested in QCA988X with firmware ver 10.2.4.70.45 Tested in QCA4019 with firmware ver 10.4-3.2.1.1-00011 Signed-off-by: Maharaja Kennadyrajan <mkenna@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-07-30ath10k: handle mgmt tx completion eventRakesh Pillai
WCN3990 transmits management frames via WMI with reference. Currently, with the management tx completion not being handled, these frames are not getting freed even after the transmission status is returned by the firmware. The transmitted management frames should be freed when the firmware sends the over-the-air tx status of the corresponding management frames. Handle the wmi mgmt tx completion event and free the corresponding management frame.

2018-07-30ath10k: disable bundle mgmt tx completion event supportSurabhi Vishnoi
The tx completion of multiple mgmt frames can be bundled in a single event and sent by the firmware to host, if this capability is not disabled explicitly by the host. If the host cannot handle the bundled mgmt tx completion, this capability support needs to be disabled in the wmi init cmd, sent to the firmware. Add the host capability indication flag in the wmi ready command, to let firmware know the features supported by the host driver. This field is ignored if it is not supported by firmware. Set the host capability indication flag(i.e. host_capab) to zero, for disabling the support of bundle mgmt tx completion. This will indicate the firmware to send completion event for every mgmt tx completion, instead of bundling them together and sending in a single event.
