Three conflicts, one of which, for marvell10g.c is non-trivial and requires some follow-up from Heiner or someone else. The issue is that Heiner converted the marvell10g driver over to use the generic c45 code as much as possible. However, in 'net' a bug fix appeared which makes sure that a new local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0 is cleared. Signed-off-by: David S. Miller <davem@davemloft.net>

2019-02-24i2c: Allow recovery of the initial IRQ by an I2C client device.Jim Broadus
A previous change allowed I2C client devices to discover new IRQs upon reprobe by clearing the IRQ in i2c_device_remove. However, if an IRQ was assigned in i2c_new_device, that information is lost. For example, the touchscreen and trackpad devices on a Dell Inspiron laptop are I2C devices whose IRQs are defined by ACPI extended IRQ types. The client device structures are initialized during an ACPI walk. After removing the i2c_hid device, modprobe fails. This change caches the initial IRQ value in i2c_new_device and then resets the client device IRQ to the initial value in i2c_device_remove.

2019-02-23net: phy: realtek: Dummy IRQ calls for RTL8366RBLinus Walleij
This fixes a regression introduced by commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7 "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

2019-02-22net/mlx5e: Fix GRE key by controlling port tunnel entropy calculationEli Britstein
Flow entropy is calculated on the inner packet headers and used for flow distribution in processing, routing etc. For GRE-type encapsulations the entropy value is placed in the eight LSB of the key field in the GRE header as defined in NVGRE RFC 7637. For UDP based encapsulations the entropy value is placed in the source port of the UDP header. The hardware may support entropy calculation specifically for GRE and for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add GRE protocol offloading") GRE is offloaded, but the hardware is configured by default to calculate flow entropy so packets transmitted on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN), GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the hardware behaviour must be controlled by the driver. Ensure port entropy calculation is enabled for offloaded VXLAN tunnels and disable port entropy calculation in the presence of offloaded GRE tunnels by monitoring the presence of entropy enabling tunnels (i.e VXLAN) and entropy disabing tunnels (i.e GRE).

2019-02-22net/mlx5: Introduce tunnel entropy control in PCMR registerEli Britstein
When using the device packet encapsulation offload, the device calculates an entropy value, representing the inner packet headers. The entropy field is placed inside the outer packet headers. For UDP-type encapsulations, the entropy is placed in the source port field of the UDP header. For GRE-type encapsulations, the entropy is placed in the 8 LSB of the key field in the GRE header. If the device does not recognize the encapsulation type, the entropy is not placed in the packet. Entropy setting can be controlled using PCMR register. if encapsulation offload is not used force_entropy_cap should be set to 0x0. Entropy setting is enabled/disabled using entropy_calc, and could be additionally enabled/disabled for GRE encapsulation by entropy_gre_calc. As a pre-step to automatically control the tunnel entropy, introduce the entropy fields in the PCMR register with no functional change.

2019-02-22net: Don't set transport offset to invalid valueMaxim Mikityanskiy
If the socket was created with socket(AF_PACKET, SOCK_RAW, 0), skb->protocol will be unset, __skb_flow_dissect() will fail, and skb_probe_transport_header() will fall back to the offset_hint, making the resulting skb_transport_offset incorrect. If, however, there is no transport header in the packet, transport_header shouldn't be set to an arbitrary value. Fix it by leaving the transport offset unset if it couldn't be found, to be explicit rather than to fill it with some wrong value. It changes the behavior, but if some code relied on the old behavior, it would be broken anyway, as the old one is incorrect.

2019-02-22perf, pt, coresight: Fix address filters for vmas with non-zero offsetAlexander Shishkin
Currently, the address range calculation for file-based filters works as long as the vma that maps the matching part of the object file starts from offset zero into the file (vm_pgoff==0). Otherwise, the resulting filter range would be off by vm_pgoff pages. Another related problem is that in case of a partially matching vma, that is, a vma that matches part of a filter region, the filter range size wouldn't be adjusted. Fix the arithmetics around address filter range calculations, taking into account vma offset, so that the entire calculation is done before the filter configuration is passed to the PMU drivers instead of having those drivers do the final bit of arithmetics.

2019-02-22clk: fractional-divider: check parent rate only if flag is setKatsuhiro Suzuki
Custom approximation of fractional-divider may not need parent clock rate checking. For example Rockchip SoCs work fine using grand parent clock rate even if target rate is greater than parent. This patch checks parent clock rate only if CLK_SET_RATE_PARENT flag is set. For detailed example, clock tree of Rockchip I2S audio hardware. - Clock rate of CPLL is 1.2GHz, GPLL is 491.52MHz. - i2s1_div is integer divider can divide N (N is 1~128). Input clock is CPLL or GPLL. Initial divider value is N = 1. Ex) PLL = CPLL, N = 10, i2s1_div output rate is CPLL / 10 = 1.2GHz / 10 = 120MHz - i2s1_frac is fractional divider can divide input to x/y, x and y are 16bit integer. CPLL --> | selector | ---> i2s1_div -+--> | selector | --> I2S1 MCLK GPLL --> | | ,--------------' | | `--> i2s1_frac ---> | | Clock mux system try to choose suitable one from i2s1_div and i2s1_frac for master clock (MCLK) of I2S1. Bad scenario as follows: - Try to set MCLK to 8.192MHz (32kHz audio replay) Candidate setting is - i2s1_div: GPLL / 60 = 8.192MHz i2s1_div candidate is exactly same as target clock rate, so mux choose this clock source. i2s1_div output rate is changed 491.52MHz -> 8.192MHz - After that try to set to 11.2896MHz (44.1kHz audio replay) Candidate settings are - i2s1_div : CPLL / 107 = 11.214945MHz - i2s1_frac: i2s1_div = 8.192MHz This is because clk_fd_round_rate() thinks target rate (11.2896MHz) is higher than parent rate (i2s1_div = 8.192MHz) and returns parent clock rate. Above is current upstreamed behavior. Clock mux system choose i2s1_div, but this clock rate is not acceptable for I2S driver, so users cannot replay audio. Expected behavior is: - Try to set master clock to 11.2896MHz (44.1kHz audio replay) Candidate settings are - i2s1_div : CPLL / 107 = 11.214945MHz - i2s1_frac: i2s1_div * 147/6400 = 11.2896MHz Change i2s1_div to GPLL / 1 = 491.52MHz at same time. If apply this commit, clk_fd_round_rate() calls custom approximate function of Rockchip even if target rate is higher than parent. Custom function changes both grand parent (i2s1_div) and parent (i2s_frac) settings at same time. Clock mux system can choose i2s1_frac and audio works fine.

This commit exports the wilco_ec_mailbox() function so that other modules can use it to communicate with the EC.

2019-02-21drivers: provide devm_platform_ioremap_resource()Bartosz Golaszewski
There are currently 1200+ instances of using platform_get_resource() and devm_ioremap_resource() together in the kernel tree. This patch wraps these two calls in a single helper. Thanks to that we don't have to declare a local variable for struct resource * and can omit the redundant argument for resource type. We also have one function call less.

2019-02-21irqdomain: Allow the default irq domain to be retrievedMarc Zyngier
The default irq domain allows legacy code to create irqdomain mappings without having to track the domain it is allocating from. Setting the default domain is a one shot, fire and forget operation, and no effort was made to be able to retrieve this information at a later point in time. Newer irqdomain APIs (the hierarchical stuff) relies on both the irqchip code to track the irqdomain it is allocating from, as well as some form of firmware abstraction to easily identify which piece of HW maps to which irq domain (DT, ACPI). For systems without such firmware (or legacy platform that are getting dragged into the 21st century), things are a bit harder. For these cases (and these cases only!), let's provide a way to retrieve the default domain, allowing the use of the v2 API without having to resort to platform-specific hacks.

2019-02-20remoteproc: fix recovery procedureLoic Pallardy
Commit 7e83cab824a87e83cab824a8 ("remoteproc: Modify recovery path to use rproc_{start,stop}()") replaces rproc_{shutdown,boot}() with rproc_{stop,start}(), which skips destroy the virtio device at stop but re-initializes it again at start. Issue is that struct virtio_dev is not correctly reinitialized like done at initial allocation thanks to kzalloc() and kobject is considered as already initialized by kernel. That is due to the fact struct virtio_dev is allocated and released at vdev resource handling level managed and virtio device is registered and unregistered at rproc subdevices level. Moreover kernel documentation mentions that device struct must be zero initialized before calling device_initialize(). This patch disentangles struct virtio_dev from struct rproc_vdev as the two struct don't have the same life-cycle. struct virtio_dev is now allocated on rproc_start() and released on rproc_stop(). This patch applies on top of patch remoteproc: create vdev subdevice with specific dma memory pool [1] [1]: https://patchwork.kernel.org/patch/10755781/ Fixes: 7e83cab824a8 ("remoteproc: Modify recovery path to use rproc_{start,stop}()") Reported-by: Xiang Xiao <xiaoxiang781216@gmail.com> Signed-off-by: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2019-02-20XArray: Fix xa_release in allocating arraysMatthew Wilcox
xa_cmpxchg() was a little too magic in turning ZERO entries into NULL, and would leave the entry set to the ZERO entry instead of releasing it for future use.

Add several tests to the test-suite to make sure this problem doesn't come back. Reported-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Matthew Wilcox <willy@infradead.org>
2019-02-20KVM: Expose the initial start value in grow_halt_poll_ns() as a module parameterNir Weiner
The hard-coded value 10000 in grow_halt_poll_ns() stands for the initial start value when raising up vcpu->halt_poll_ns. It actually sets the first timeout to the first polling session. This value has significant effect on how tolerant we are to outliers. On the standard case, higher value is better - we will spend more time in the polling busyloop, handle events/interrupts faster and result in better performance. But on outliers it puts us in a busy loop that does nothing. Even if the shrink factor is zero, we will still waste time on the first iteration. The optimal value changes between different workloads. It depends on outliers rate and polling sessions length. As this value has significant effect on the dynamic halt-polling algorithm, it should be configurable and exposed.

2019-02-20KVM: Move the memslot update in-progress flag to bit 63Sean Christopherson
...now that KVM won't explode by moving it out of bit 0. Using bit 63 eliminates the need to jump over bit 0, e.g. when calculating a new memslots generation or when propagating the memslots generation to an MMIO spte.

2019-02-20KVM: Explicitly define the "memslot update in-progress" bitSean Christopherson
KVM uses bit 0 of the memslots generation as an "update in-progress" flag, which is used by x86 to prevent caching MMIO access while the memslots are changing. Although the intended behavior is flag-like, e.g. MMIO sptes intentionally drop the in-progress bit so as to avoid caching data from in-flux memslots, the implementation oftentimes treats the bit as part of the generation number itself, e.g. incrementing the generation increments twice, once to set the flag and once to clear it. Prior to commit 4bd518f1598d ("KVM: use separate generations for each address space"), incorporating the "update in-progress" bit into the generation number largely made sense, e.g. "real" generations are even, "bogus" generations are odd, most code doesn't need to be aware of the bit, etc... Now that unique memslots generation numbers are assigned to each address space, stealthing the in-progress status into the generation number results in a wide variety of subtle code, e.g. kvm_create_vm() jumps over bit 0 when initializing the memslots generation without any hint as to why. Explicitly define the flag and convert as much code as possible (which isn't much) to actually treat it like a flag. This paves the way for eventually using a different bit for "update in-progress" so that it can be a flag in truth instead of a awkward extension to the generation number.
