2018-08-23drivers/gpu/drm/gma500/: change return type to vm_fault_tSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_{pfn,mixed} returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_{pfn,mixed} will replace this inefficiency by returning VM_FAULT_* type. vmf_error() is the newly introduce inline function in 4.17-rc6.

2018-08-23ice: Set VLAN flags correctlyBrett Creeley
In the struct ice_aqc_vsi_props the field port_vlan_flags is an overloaded term because it is used for both port VLANs (PVLANs) and regular VLANs. This is an issue and is very confusing especially when dealing with VFs because normal VLANs and port VLANs are not the same. To fix this the field was renamed to vlan_flags and all of the #define's labeled *_PVLAN_* were renamed to *_VLAN_* if they are not specific to port VLANs. Also in ice_vsi_manage_vlan_stripping, set the ICE_AQ_VSI_VLAN_MODE_ALL bit to allow the driver to add a VLAN tag to all packets it sends.

2018-08-23ice: Use order_base_2 to calculate higher power of 2Jacob Keller
Currently, we use a combination of ilog2 and is_power_of_2() to calculate the next power of 2 for the qcount. This appears to be causing a warning on some combinations of GCC and the Linux kernel: MODPOST 1 modules WARNING: "____ilog2_NaN" [ice.ko] undefined! This appears to because because GCC realizes that qcount could be zero in some circumstances and thus attempts to link against the intentionally undefined ___ilog2_NaN function. The order_base_2 function is intentionally defined to return 0 when passed 0 as an argument, and thus will be safe to use here. This not only fixes the warning but makes the resulting code slightly cleaner, and is really what we should have used originally. Also update the comment to make it more clear that we are rounding up, not just incrementing the ilog2 of qcount unconditionally.

The bits PFINT_FW_CTL, PFINT_MBX_CTL and PFINT_SB_CTL are not set when an interrupt arrives, which means that clearing them again can be omitted. 2) Get an accurate value in "pending" by re-reading the control queue head register from the hardware. 3) Fix a corner case involving lost control queue messages by checking for new control messages (using ice_ctrlq_pending) before exiting the cleanup routine.

2018-08-23ice: Report stats for allocated queues via ethtool statsJacob Keller
It is not safe to have the string table for statistics change order or size over the lifetime of a given netdevice. This is because of the nature of the 3-step process for obtaining stats. First, user space performs a request for the size of the strings table. Second it performs a separate request for the strings themselves, after allocating space for the table. Third, it requests the stats themselves, also allocating space for the table. If the size decreased, there is potential to see garbage data or stats values. In the worst case, we could potentially see stats values become mis-aligned with their strings, so that it looks like a statistic is being reported differently than it actually is. Even worse, if the size increased, there is potential that the strings table or stats table was not allocated large enough and the stats code could access and write to memory it should not, potentially resulting in undefined behavior and system crashes. It isn't even safe if the size always changes under the RTNL lock. This is because the calls take place over multiple user space commands, so it is not possible to hold the RTNL lock for the entire duration of obtaining strings and stats. Further, not all consumers of the ethtool API are the user space ethtool program, and it is possible that one assumes the strings will not change (valid under the current contract), and thus only requests the stats values when requesting stats in a loop. Finally, it's not possible in the general case to detect when the size changes, because it is quite possible that one value which could impact the stat size increased, while another decreased. This would result in the same total number of stats, but reordering them so that stats no longer line up with the strings they belong to. Since only size changes aren't enough, we would need some sort of hash or token to determine when the strings no longer match. This would require extending the ethtool stats commands, but there is no more space in the relevant structures. The real solution to resolve this would be to add a completely new API for stats, probably over netlink. In the ice driver, the only thing impacting the stats that is not constant is the number of queues. Instead of reporting stats for each used queue, report stats for each allocated queue. We do not change the number of queues allocated for a given netdevice, as we pass this into the alloc_etherdev_mq() function to set the num_tx_queues and num_rx_queues.

2018-08-23ice: Fix multiple static analyser warningsAnirudh Venkataramanan
This patch fixes the following smatch errors: 1) Fix "odd binop '0x0 & 0xc'" when performing the bitwise-and with a constant value of zero (ICE_AQC_GSET_RSS_LUT_TABLE_SIZE_128_FLAG). Remove a similar bitwise-and with 0 in ice_add_marker_act() and use the right mask ICE_LG_ACT_GENERIC_OFFSET_M in the expression. 2) Fix a similar issue "odd binop '0x0 & 0x1800' in ice_req_irq_msix_misc. 3) Fix "odd binop '0x380000 & 0x7fff8'" in ice_add_marker_act(). Also, use a new define ICE_LG_ACT_GENERIC_OFF_RX_DESC_PROF_IDX instead of magic number '7'. 4) Fix warn: odd binop '0x0 & 0x18' in ice_set_dflt_vsi_ctx() by removing unnecessary logic to explicitly unset bits 3 and 4 in port_vlan_bits. These bits are unset already by the memset on ctxt->info.

2018-08-23ACPI: fix menuconfig presentation of ACPI submenuArnd Bergmann
My fix for a recursive Kconfig dependency caused another issue where the ACPI specific options end up in the top-level menu in 'menuconfig'. This was an unintended side-effect of having a silent option between 'menuconfig ACPI' and 'if ACPI'. Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that problem and restores the previous presentation.

2018-08-22include/linux/compiler*.h: make compiler-*.h mutually exclusiveNick Desaulniers
Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6") recently exposed a brittle part of the build for supporting non-gcc compilers. Both Clang and ICC define __GNUC__, __GNUC_MINOR__, and __GNUC_PATCHLEVEL__ for quick compatibility with code bases that haven't added compiler specific checks for __clang__ or __INTEL_COMPILER. This is brittle, as they happened to get compatibility by posing as a certain version of GCC. This broke when upgrading the minimal version of GCC required to build the kernel, to a version above what ICC and Clang claim to be. Rather than always including compiler-gcc.h then undefining or redefining macros in compiler-intel.h or compiler-clang.h, let's separate out the compiler specific macro definitions into mutually exclusive headers, do more proper compiler detection, and keep shared definitions in compiler_types.h.

The driver notifies user on hotplug device signal receiving. - ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. - ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. - Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. * tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits) platform/x86: acer-wmi: Silence "unsupported" message a bit platform/x86: intel_punit_ipc: fix build errors platform/x86: ideapad: Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360 platform/x86: acer-wmi: refactor function has_cap platform/x86: thinkpad_acpi: Fix multi-battery bug platform/x86: thinkpad_acpi: extend battery quirk coverage platform/x86: touchscreen_dmi: Add info for the Cube KNote i1101 tablet platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init() platform/x86: mlx-platform: Remove unused define platform/x86: mlx-platform: Change mlxreg-io configuration for MSN274x systems Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Allow mlxreg-io driver activation for more systems platform/x86: mlx-platform: Add ASIC hotplug device configuration platform/mellanox: mlxreg-hotplug: Add hotplug hwmon uevent notification platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery platform/x86: mlx-platform: Add mlxreg-fan platform driver activation platform/x86: dell-laptop: Fix backlight detection platform/x86: toshiba_acpi: Fix defined but not used build warnings platform/x86: thinkpad_acpi: Support battery quirk ...
