2017-09-04video: fbdev: annotate fb_fix_screeninfo with const and __initconstBhumika Goyal
Make these const as they are only used during a copy operation. Some structures are used as a copy operation inside __init functions, so make them const and replace __initdata with __initconst to avoid section conflict error.

2017-09-04irqchip: mips-gic: Let the core set struct irq_common_data affinityPaul Burton
gic_set_affinity() manually copies the provided cpumask to the struct irq_common_data affinity field, returning IRQ_SET_MASK_OK_NOCOPY in order to prevent the core code from doing that. We can instead simply let the core code do it for us, by returning IRQ_SET_MASK_OK instead of IRQ_SET_MASK_OK_NOCOPY & doing the copy ourselves.

2017-09-04irqchip: mips-gic: Use cpumask_first_and() in gic_set_affinity()Paul Burton
Currently in gic_set_affinity() we calculate a temporary cpumask holding the intersection of the provided cpumask & the CPUs that are online, then we call cpumask_first twice on it to find the first such CPU. Since we don't need the temporary cpumask for anything else & we only care about the first CPU that's both online & in the provided cpumask, we can instead use cpumask_first_and to find that CPU & drop the temporary mask.

2017-09-04irqchip: mips-gic: Clean up mti, reserved-cpu-vectors handlingPaul Burton
When parsing mti,reserved-cpu-vectors we generate a mask of all bits that have been declared reserved, the loop through starting from bit 2 to find one that isn't reserved (ie. is zero). This patch accomplishes the same task more simply by: - Inititialising the reserved mask to 0x3 (ie. the 2 software interrupts). This means we don't need to skip them later as the loop previously has. - Replacing the loop checking for zero bits with find_first_zero_bit, which fits our needs now that the 2 software interrupts are marked reserved. This requires that the type of reserved is changed to unsigned long so that it's suitable for use with bitmap functions. - Replacing the magic number 8 with the hamming weight of the ST0_IM field - ie. the number of bits that a MIPS CPU has for interrupt inputs. This is still a compile-time constant 8, but makes it clearer why it's 8.

2017-09-04irqchip: mips-gic: Use pcpu_masks to avoid reading GIC_SH_MASK*Paul Burton
This patch avoids the need to read the GIC_SH_MASK* registers when decoding shared interrupts by setting & clearing the interrupt's bit in the appropriate CPU's pcpu_masks entry when masking or unmasking the interrupt. This effectively means that whilst an interrupt is masked we clear its bit in all pcpu_masks, which causes gic_handle_shared_int() to ignore it on all CPUs without needing to check GIC_SH_MASK*. In essence, we add a little overhead to masking or unmasking interrupts but in return reduce the overhead of the far more common task of decoding interrupts.

2017-09-03net: qualcomm: rmnet: Refactor the new rmnet dev creationSubash Abhinov Kasiviswanathan
Data format can be directly set from rmnet_newlink() since the rmnet real dev info is already available. Since __rmnet_get_real_dev_info() is no longer used in rmnet_config.c after removal of those functions, move content to rmnet_get_real_dev_info(). __rmnet_set_endpoint_config() is collapsed into rmnet_set_endpoint_config() since only mux_id was being set additionally within it. Remove an unnecessary mux_id check. Set the mux_id for the rmnet_dev within rmnet_vnd_newlink() itself.

rmnet_rtnl_validate() was checking for upto mux_id 254, however the rmnet_devices devices could hold upto 32 entries only. Fix this by increasing the size of the rmnet_devices.

2017-09-03nfp: flower: restore RTNL locking around representor updatesJakub Kicinski
When we moved to updating representors from a workqueue grabbing the RTNL somehow got lost in the process. Restore it, and make sure RCU lock is not held while we are grabbing the RTNL. RCU protects the representor table, so since we will be under RTNL we can drop RCU lock as soon as we find the netdev pointer. RTNL is needed for the dev_set_mtu() call.
