2017-09-04irqchip: mips-gic: Let the core set struct irq_common_data affinityPaul Burton1-2/+1
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 Burton1-6/+6
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 Burton1-7/+7
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 Burton1-21/+31
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.

The __gic_init() function is only called from gic_of_init() now that the non-DT path has been removed. In order to simplify the code & aid readability, fold __gic_init() into gic_of_init(). This provides us with the ability to return an error code, which __gic_init() was previously unable to do.

2017-09-03net: qualcomm: rmnet: Fix memory corruption if mux_id is greater than 32Subash Abhinov Kasiviswanathan3-4/+2
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 Kicinski1-2/+4
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.

2017-09-03nfp: build the flower offload by defaultJakub Kicinski1-0/+1
It's reasonable to assume that if user selects to build the NFP driver all offload capabilities will be enabled by default. Change the CONFIG_NFP_APP_FLOWER to default to enabled.

2017-09-03nfp: move the start/stop app callbacks backJakub Kicinski1-15/+11
Since representors are now created with a separate callback start/stop app callbacks can be moved again to their original location. They are intended to app-specific init/clean up over the control channel. Signed-off-by: Jakub Kicinski <[email protected]> Reviewed-by: Simon Horman <[email protected]> Signed-off-by: David S.
