2019-02-19RDMA/device: Provide APIs from the core code to help unregistrationJason Gunthorpe
These APIs are intended to support drivers that exist outside the usual driver core probe()/remove() callbacks. Normally the driver core will prevent remove() from running concurrently with probe(), once this safety is lost drivers need more support to get the locking and lifetimes right. ib_unregister_driver() is intended to be used during module_exit of a driver using these APIs. It unregisters all the associated ib_devices. ib_unregister_device_and_put() is to be used by a driver-specific removal function (ie removal by name, removal from a netdev notifier, removal from netlink) ib_unregister_queued() is to be used from netdev notifier chains where RTNL is held. The locking is tricky here since once things become async it is possible to race unregister with registration. This is largely solved by relying on the registration refcount, unregistration will only ever work on something that has a positive registration refcount - and then an unregistration mutex serializes all competing unregistrations of the same device.

2019-02-19RDMA/device: Add ib_device_get_by_netdev()Jason Gunthorpe
Several drivers need to find the ib_device from a given netdev. rxe needs this at speed in an unsleepable context, so choose to implement the translation using a RCU safe hash table. The hash table can have a many to one mapping. This is intended to support some future case where multiple IB drivers (ie iWarp and RoCE) connect to the same netdevs. driver_ids will need to be different to support this. In the process this makes the struct ib_device and ib_port_data RCU safe by deferring their kfrees. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2019-02-19RDMA/device: Add ib_device_set_netdev() as an alternative to get_netdevJason Gunthorpe
The associated netdev should not actually be very dynamic, so for most drivers there is no reason for a callback like this. Provide an API to inform the core code about the net dev affiliation and use a core maintained data structure instead. This allows the core code to be more aware of the ndev relationship which will allow some new APIs based around this. This also uses locking that makes some kind of sense, many drivers had a confusing RCU lock, or missing locking which isn't right. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

2019-02-19scsi: fcoe: make use of fip_mode enum completeSedat Dilek
commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate enum for the fip_mode that shall be used during initialisation handling until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That change was incomplete and gcc quietly converted in various places between the fip_mode and the fip_state enum values with implicit enum conversions, which fortunately cannot cause any issues in the actual code's execution. clang however warns about these implicit enum conversions in the scsi drivers. This commit consolidates the use of the two enums, guided by clang's enum-conversion warnings. This commit now completes the use of the fip_mode: It expects and uses fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to indicate these two enums are distinct.

2019-02-19KVM: arm/arm64: Rework the timer code to use a timer_mapChristoffer Dall
We are currently emulating two timers in two different ways. When we add support for nested virtualization in the future, we are going to be emulating either two timers in two diffferent ways, or four timers in a single way. We need a unified data structure to keep track of how we map virtual state to physical state and we need to cleanup some of the timer code to operate more independently on a struct arch_timer_context instead of trying to consider the global state of the VCPU and recomputing all state.

Actually they are quite similar, and we rely on kvm_arm_timer_[gs]et_reg() for the actual emulation anyways, so let's just merge all of those handlers into one function, which just marshalls the arguments and then hands off to a set of common accessors.

2019-02-19KVM: arm/arm64: Simplify bg_timer programmingChristoffer Dall
Instead of calling into kvm_timer_[un]schedule from the main kvm blocking path, test if the VCPU is on the wait queue from the load/put path and perform the background timer setup/cancel in this path. This has the distinct advantage that we no longer race between load/put and schedule/unschedule and programming and canceling of the bg_timer always happens when the timer state is not loaded. Note that we must now remove the checks in kvm_timer_blocking that do not schedule a background timer if one of the timers can fire, because we no longer have a guarantee that kvm_vcpu_check_block() will be called before kvm_timer_blocking.

2019-02-19clocksource/arm_arch_timer: Store physical timer IRQ number for KVM on VHEAndre Przywara
A host running in VHE mode gets the EL2 physical timer as its time source (accessed using the EL1 sysreg accessors, which get re-directed to the EL2 sysregs by VHE). The EL1 physical timer remains unused by the host kernel, allowing us to pass that on directly to a KVM guest and saves us from emulating this timer for the guest on VHE systems. Store the EL1 Physical Timer's IRQ number in struct arch_timer_kvm_info on VHE systems to allow KVM to use it.

2019-02-19asm-generic: Make time32 syscall numbers optionalArnd Bergmann
We don't want new architectures to even provide the old 32-bit time_t based system calls any more, or define the syscall number macros. Add a new __ARCH_WANT_TIME32_SYSCALLS macro that gets enabled for all existing 32-bit architectures using the generic system call table, so we don't change any current behavior. Since this symbol is evaluated in user space as well, we cannot use a Kconfig CONFIG_* macro but have to define it in uapi/asm/unistd.h. On 64-bit architectures, the same system call numbers mostly refer to the system calls we want to keep, as they already pass 64-bit time_t. As new architectures no longer provide these, we need new exceptions in checksyscalls.sh. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2019-02-19PM / core: Add support to skip power management in device/driver modelSudeep Holla
All device objects in the driver model contain fields that control the handling of various power management activities. However, it's not always useful. There are few instances where pseudo devices are added to the model just to take advantage of many other features like kobjects, udev events, and so on. One such example is cpu devices and their caches. The sysfs for the cpu caches are managed by adding devices with cpu as the parent in cpu_device_create() when secondary cpu is brought online. Generally when the secondary CPUs are hotplugged back in as part of resume from suspend-to-ram, we call cpu_device_create() from the cpu hotplug state machine while the cpu device associated with that CPU is not yet ready to be resumed as the device_resume() call happens bit later. It's not really needed to set the flag is_prepared for cpu devices as they are mostly pseudo device and hotplug framework deals with state machine and not managed through the cpu device. This often results in annoying warning when resuming: Enabling non-boot CPUs ... CPU1: Booted secondary processor cache: parent cpu1 should not be sleeping CPU1 is up CPU2: Booted secondary processor cache: parent cpu2 should not be sleeping CPU2 is up .... and so on. So in order to fix these kind of errors, we could just completely avoid doing any power management related initialisations and operations if they are not used by these devices. Add no_pm flags to indicate that the device doesn't require any sort of PM activities and all of them can be completely skipped. We can use the same flag to also avoid adding not used *power* sysfs entries for these devices. For now, lets use this for cpu cache devices.

2019-02-1932-bit userspace ABI: introduce ARCH_32BIT_OFF_T config optionYury Norov
All new 32-bit architectures should have 64-bit userspace off_t type, but existing architectures has 32-bit ones. To enforce the rule, new config option is added to arch/Kconfig that defaults ARCH_32BIT_OFF_T to be disabled for new 32-bit architectures. All existing 32-bit architectures enable it explicitly. New option affects force_o_largefile() behaviour. Namely, if userspace off_t is 64-bits long, we have no reason to reject user to open big files. Note that even if architectures has only 64-bit off_t in the kernel (arc, c6x, h8300, hexagon, nios2, openrisc, and unicore32), a libc may use 32-bit off_t, and therefore want to limit the file size to 4GB unless specified differently in the open flags.

In every case, the actual return type is a struct vb2_v4l2_buffer pointer. Change the return type of the listed functions, so type checking can be properly used.

2019-02-18media: vb2: keep track of timestamp statusHans Verkuil
If a stream is stopped, or if a USERPTR/DMABUF buffer is queued backed by a different user address or dmabuf fd, then the timestamp should be skipped by vb2_find_timestamp since the memory it refers to is no longer valid. So keep track of a 'copied_timestamp' state: it is set when the timestamp is copied from an output to a capture buffer, and is cleared when it is no longer valid.

2019-02-18media: v4l: Add 32-bit packed YUV formatsVivek Kasireddy
The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.

2019-02-18drm/audio: declaration of struct deviceRamalingam C
Header has used the references to struct device without it definition or declaration. Hence resulting in compilation warning such as "'struct device' declared inside parameter list..." This changes adds a declaration to struct device in the header to avoid any such warnings.

2019-02-18media: v4l2-subdev.h: v4l2_subdev_call: use temp __sd variableHans Verkuil
The sd argument of this macro can be a more complex expression. Since it is used 5 times in the macro it can be evaluated that many times as well. So assign it to a temp variable in the beginning and use that instead. This also avoids any potential side-effects of evaluating sd.

2019-02-18compat ABI: use non-compat openat and open_by_handle_at variantsYury Norov
The only difference between native and compat openat and open_by_handle_at is that non-compat version forces O_LARGEFILE, and it should be the default behaviour for all architectures, as we are going to drop the support of 32-bit userspace off_t.
