2017-04-28misc: Add host side PCI driver for PCI test function deviceKishon Vijay Abraham I2-0/+20
Add PCI endpoint test driver that can verify base address register, legacy interrupt/MSI interrupt and read/write/copy buffers between host and device. The corresponding pci-epf-test function driver should be used on the EP side. Signed-off-by: Kishon Vijay Abraham I <[email protected]> Signed-off-by: Bjorn Helgaas <[email protected]>

2017-04-28blk-mq: unify hctx delay_work and run_workJens Axboe1-2/+1
The only difference between ->run_work and ->delay_work, is that the latter is used to defer running a queue. This is done by marking the queue stopped, and scheduling ->delay_work to run sometime in the future. While the queue is stopped, direct runs or runs through ->run_work will not run the queue. If we combine the handlers, then we need to handle two things: 1) If a delayed/stopped run is scheduled, then we should not run the queue before that has been completed. 2) If a queue is delayed/stopped, the handler needs to restart the queue. Normally a run of a queue with the stopped bit set would be a no-op. Case 1 is handled by modifying a currently pending queue run to the deadline set by the caller of blk_mq_delay_queue(). Subsequent attempts to queue a queue run will find the work item already pending, and direct runs will see a stopped queue as before. Case 2 is handled by adding a new bit, BLK_MQ_S_START_ON_RUN, that tells the work handler that it should clear a stopped queue and run the handler.

2017-04-27bridge: add per-port broadcast flood flagMike Manning2-0/+2
Support for l2 multicast flood control was added in commit b6cb5ac8331b ("net: bridge: add per-port multicast flood flag"). It allows broadcast as it was introduced specifically for unknown multicast flood control. But as broadcast is a special case of multicast, this may also need to be disabled. For this purpose, introduce a flag to disable the flooding of received l2 broadcasts. This approach is backwards compatible and provides flexibility in filtering for the desired packet types.

2017-04-27rhashtable: Cap total number of entries to 2^31Herbert Xu1-2/+3
When max_size is not set or if it set to a sufficiently large value, the nelems counter can overflow. This would cause havoc with the automatic shrinking as it would then attempt to fit a huge number of entries into a tiny hash table. This patch fixes this by adding max_elems to struct rhashtable to cap the number of elements. This is set to 2^31 as nelems is not a precise count. This is sufficiently smaller than UINT_MAX that it should be safe. When max_size is set max_elems will be lowered to at most twice max_size as is the status quo.

kvm_vcpu_kick() must issue a general memory barrier prior to reading vcpu->mode in order to ensure correctness of the mutual-exclusion memory barrier pattern used with vcpu->requests. While the cmpxchg called from kvm_vcpu_kick(): kvm_vcpu_kick kvm_arch_vcpu_should_kick kvm_vcpu_exiting_guest_mode cmpxchg implies general memory barriers before and after the operation, that implication is only valid when cmpxchg succeeds. We need an explicit barrier for when it fails, otherwise a VCPU thread on its entry path that reads zero for vcpu->requests does not exclude the possibility the requesting thread sees !IN_GUEST_MODE when it reads vcpu->mode. kvm_make_all_cpus_request already had a barrier, so we remove it, as now it would be redundant.

Some operations must ensure that the guest is not running with stale data, but if the guest is halted, then the update can wait until another event happens. kvm_make_all_requests() currently doesn't wake up, so we can mark all requests used with it. First 8 bits were arbitrarily reserved for request numbers. Most uses of requests have the request type as a constant, so a compiler will optimize the '&'. An alternative would be to have an inline function that would return whether the request needs a wake-up or not, but I like this one better even though it might produce worse assembly.

After this change, no more access to PMU regmap is needed, so remove also the code for handling PMU regmap.

2017-04-27mfd: Add support for DA9061Steve Twiss2-4/+30
MFD support for DA9061 is provided as part of the DA9062 device driver. The registers header file adds two new chip variant IDs defined in DA9061 and DA9062 hardware. The core header file adds new software enumerations for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration for distinguishing between DA9061/62 devices in software. The core source code adds a new .compatible of_device_id entry. This is extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The .data entry now holds a reference to the enumerated device type. A new regmap_irq_chip model is added for DA9061 and this supports the new list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the new sub system components for DA9061. Support is added for a new DA9061 regmap_config which lists the correct readable, writable and volatile ranges for this chip. The probe function uses the device tree compatible string to switch on the da9062_compatible_types and configure the correct mfd cells, irq chip and regmap config. Kconfig is updated to reflect support for DA9061 and DA9062 PMICs. Signed-off-by: Steve Twiss <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2017-04-27mfd: syscon: atmel-smc: Remove unused helpers/macrosBoris Brezillon1-152/+0
All macros prefixed with AT91[SAM9]_SMC have been replaced by equivalent definitions prefixed with ATMEL_SMC, and the at91sam9_smc_xxxx() helpers are no longer used. Drop these definitions before someone starts using them again.

2017-04-27mfd: syscon: atmel-smc: Add new helpers to ease SMC regs manipulationBoris Brezillon1-0/+87
These new helpers + macro definitions are meant to replace the old ones which are unpractical to use. Note that the macros and function prefixes have been intentionally changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that this IP is also embedded in avr32 SoCs (and not only in at91 ones).

2017-04-27mfd: axp20x: Correct name of temperature data ADC registersQuentin Schulz1-2/+2
The registers 0x56 and 0x57 of AXP22X PMIC store the value of the internal temperature of the PMIC. This patch modifies the name of these registers from AXP22X_PMIC_ADC_H/L to AXP22X_PMIC_TEMP_H/L so their purpose is clearer.

2017-04-27mfd: Add TI LMU driverMilo Kim2-0/+367
TI LMU (Lighting Management Unit) driver supports lighting devices below. LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697. LMU devices have common features. - I2C interface for accessing device registers - Hardware enable pin control - Backlight brightness control - Notifier for hardware fault monitoring - Regulators for LCD display bias It contains fault monitor, backlight, LED and regulator driver. LMU fault monitor ----------------- LM3633 and LM3697 provide hardware monitoring feature. It enables open or short circuit detection. After monitoring is done, each device should be re-initialized. Notifier is used for this case. Separate patch for 'ti-lmu-fault-monitor' will be sent later. Backlight --------- It's handled by TI LMU backlight consolidated driver and chip dependent data. Separate patchset will be sent later. LED indicator ------------- LM3633 has 6 indicator LEDs. Programmable dimming pattern is also supported. Separate patch for 'leds-lm3633' will be sent later. Regulator --------- LM3631 has 5 regulators for the display bias. LM3632 supports 3 regulators. One consolidated driver enables it. The lm363x regulator driver is already upstreamed.

2017-04-26fs: remove _submit_bh()Eric Biggers1-2/+0
_submit_bh() allowed submitting a buffer_head for I/O using custom bio_flags. It used to be used by jbd to set BIO_SNAP_STABLE, introduced by commit 713685111774 ("mm: make snapshotting pages for stable writes a per-bio operation"). However, the code and flag has since been removed and no _submit_bh() users remain. These days, bio_flags are mostly used internally by the block layer to track the state of bio's. As such, it doesn't really make sense for filesystems to use them instead of op_flags when wanting special behavior for block requests. Therefore, remove _submit_bh() and trim the bio_flags argument from submit_bh_wbc(). Cc: Darrick J.

2017-04-26fs: constify tree_descr arrays passed to simple_fill_super()Eric Biggers1-2/+3
simple_fill_super() is passed an array of tree_descr structures which describe the files to create in the filesystem's root directory. Since these arrays are never modified intentionally, they should be 'const' so that they are placed in .rodata and benefit from memory protection. This patch updates the function signature and all users, and also constifies tree_descr.name. Signed-off-by: Eric Biggers <[email protected]> Signed-off-by: Al Viro <[email protected]>
