With commit 2d55173e71b0 ("phy: add generic function to support ksetting support"), we lost the ability to report the transceiver type like we used to. Now that we have added back the transceiver type to ethtool_link_settings, we can report it back like we used to and have no loss of information.

2017-09-21net: qcom/emac: add software control for pause frame modeTimur Tabi
The EMAC has the option of sending only a single pause frame when flow control is enabled and the RX queue is full. Although sending only one pause frame has little value, this would allow admins to enable automatic flow control without having to worry about the EMAC flooding nearby switches with pause frames if the kernel hangs. The option is enabled by using the single-pause-mode private flag. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-09-21hv_netvsc: fix send buffer failure on MTU changeAlex Ng
If MTU is changed the host would reject the send buffer change. This problem is result of recent change to allow changing send buffer size. Every time we change the MTU, we store the previous net_device section count before destroying the buffer, but we don’t store the previous section size. When we reinitialize the buffer, its size is calculated by multiplying the previous count and previous size. Since we continuously increase the MTU, the host returns us a decreasing count value while the section size is reinitialized to 1728 bytes every time. This eventually leads to a condition where the calculated buf_size is so small that the host rejects it.

2017-09-20isdn/i4l: fetch the ppp_write buffer in one shotMeng Xu
In isdn_ppp_write(), the header (i.e., protobuf) of the buffer is fetched twice from userspace. The first fetch is used to peek at the protocol of the message and reset the huptimer if necessary; while the second fetch copies in the whole buffer. However, given that buf resides in userspace memory, a user process can race to change its memory content across fetches. By doing so, we can either avoid resetting the huptimer for any type of packets (by first setting proto to PPP_LCP and later change to the actual type) or force resetting the huptimer for LCP packets. This patch changes this double-fetch behavior into two single fetches decided by condition (lp->isdn_device < 0 || lp->isdn_channel <0).

2017-09-20PCI: endpoint: Use correct "end of test" interruptJohn Keeping
pci_epf_test_raise_irq() reads the interrupt to use for the response from reg->command, but this has been cleared at the beginning of the command handler so the value is always zero at this point. Instead, extract the interrupt index before handling the command and then pass the requested interrupt into pci_epf_test_raise_irq(). This allows us to remove the specific code to extract the interrupt for COMMAND_RAISE_MSI_IRQ since it is now handled in common code.

This patch is pretty much a carbon copy of commit 3079c652141f ("caif: Fix napi poll list corruption") with "caif" replaced by "emac". The commit d75b1ade567f ("net: less interrupt masking in NAPI") breaks emac. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers emac tries to do a last-ditch check and if there is more work it will call napi_reschedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in emac.

2017-09-19cpufreq: dt-platdev: Add some missing platforms to the blacklistViresh Kumar
Commit edeec420de24 (cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2) missed adding few platforms to the blacklist which create the cpufreq-dt device from their own drivers, after some dependencies are sorted out. And for those platforms, both the platform specific driver and the cpufreq-dt-platdev driver try to create the cpufreq-dt device now. Fix that by including those platforms in the blacklist. This doesn't include the TI platforms, for which there is a separate patch.

2017-09-19PM: core: Fix device_pm_check_callbacks()Rafael J. Wysocki
The device_pm_check_callbacks() function doesn't check legacy ->suspend and ->resume callback pointers under the device's bus type, class and driver, so in some cases it may set the no_pm_callbacks flag for the device incorrectly and then the callbacks may be skipped during system suspend/resume, which shouldn't happen.

2017-09-19net: phy: Kconfig: Fix PHY infrastructure menu in menuconfigJerome Brunet
Since the integration of PHYLINK, the configuration option which used to be under the PHY infrastructure menu in menuconfig ended up one level up (the network device driver section) By placing PHYLINK option right after PHYLIB entry, it broke the way Kconfig used to build the menu. See kconfig-language.txt, section "Menu structure", 2nd method. This is fixed by placing the PHYLINK option just before PHYLIB.

2017-09-19ACPI / bus: Make ACPI_HANDLE() work for non-GPL code againJohn Hubbard
Due to commit db3e50f3234b (device property: Get rid of struct fwnode_handle type field), ACPI_HANDLE() inadvertently became a GPL-only call. The call path that led to that was: ACPI_HANDLE() ACPI_COMPANION() to_acpi_device_node() is_acpi_device_node() acpi_device_fwnode_ops DECLARE_ACPI_FWNODE_OPS(acpi_device_fwnode_ops); ...and the new DECLARE_ACPI_FWNODE_OPS() includes EXPORT_SYMBOL_GPL, whereas previously it was a static struct. In order to avoid changing any of that, let's instead provide ever so slightly better encapsulation of those struct fwnode_operations instances. Those do not really need to be directly used in inline function calls in header files. Simply moving two small functions (is_acpi_device_node and is_acpi_data_node) out of acpi_bus.h, and into a .c file, does that. That leaves the internals of struct fwnode_operations as GPL-only (which I think was the intent all along), but un-breaks any driver code out there that relies on the ACPI subsystem's being (historically) an EXPORT_SYMBOL-usable system. By that, I mean, ACPI_HANDLE() and other basic ACPI calls were non-GPL-protected. Also, while I'm there, remove a tiny bit of redundancy that was missed in the earlier commit, by having is_acpi_node() use the other two routines, instead of checking fwnode directly.

Commit 7d902c05b480 ("drm: Nuke drm_atomic_helper_connector_dpms") removed drm_atomic_helper_connector_dpms() helper saying that it was a dead code. It was however indirectly used by Exynos DRM driver for implementing suspend/resume support. To fix this regression (after that patch Exynos DRM suspend/resume functions became no-ops and hardware fails to suspend), this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.

2017-09-19drm/exynos: Fix locking in the suspend/resume pathsMarek Szyprowski
Commit 48a92916729b ("drm/exynos: use drm_for_each_connector_iter()") replaced unsafe drm_for_each_connector() with drm_for_each_connector_iter() and removed surrounding drm_modeset_lock calls. However, that lock was there not only to protect unsafe drm_for_each_connector(), but it was also required to be held by the dpms code which was called from the loop body. This patch restores those drm_modeset_lock calls to fix broken suspend and resume of Exynos DRM subsystem in v4.13 kernel.

2017-09-19iommu/vt-d: Fix harmless section mismatch warningArnd Bergmann
Building with gcc-4.6 results in this warning due to dmar_table_print_dmar_entry being inlined as in newer compiler versions: WARNING: vmlinux.o(.text+0x5c8bee): Section mismatch in reference from the function dmar_walk_remapping_entries() to the function .init.text:dmar_table_print_dmar_entry() The function dmar_walk_remapping_entries() references the function __init dmar_table_print_dmar_entry(). This is often because dmar_walk_remapping_entries lacks a __init annotation or the annotation of dmar_table_print_dmar_entry is wrong. This removes the __init annotation to avoid the warning. On compilers that don't show the warning today, this should have no impact since the function gets inlined anyway.
