2017-06-30lightnvm: pblk: add initialization checkJavier González
Add a sanity check to the pblk initialization sequence in order to ensure that enough LUNs have been allocated to store the line metadata. Signed-off-by: Javier González <javier@cnexlabs.com> Signed-off-by: Matias Bjørling <matias@cnexlabs.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2017-06-30lightnvm: pblk: remove target using async. I/OsJavier González
When removing a pblk instance, pad the current line using asynchronous I/O. This reduces the removal time from ~1 minute in the worst case to a couple of seconds.

2017-06-30lightnvm: pblk: use vmalloc for GC data bufferJavier González
For now, we allocate a per I/O buffer for GC data. Since the potential size of the buffer is 256KB and GC is not in the fast path, do this allocation with vmalloc. This puts lets pressure on the memory allocator at no performance cost.

2017-06-30lightnvm: pblk: schedule if data is not readyJavier González
When user threads place data into the write buffer, they reserve space and do the memory copy out of the lock. As a consequence, when the write thread starts persisting data, there is a chance that it is not copied yet. In this case, avoid polling, and schedule before retrying.

2017-06-30drivers: dma-mapping: allow dma_common_mmap() for NOMMUVladimir Murzin
Currently, internals of dma_common_mmap() is compiled out if build is done for either NOMMU or target which explicitly says it does not have/want coherent DMA mmap. It turned out that dma_common_mmap() can be handy in NOMMU setup (at least for ARM). This patch converts exitent NOMMU targets to use ARCH_NO_COHERENT_DMA_MMAP, thus when CONFIG_MMU is gone from dma_common_mmap() their behaviour stays unchanged. ARM is not converted to ARCH_NO_COHERENT_DMA_MMAP because it 1) already has mmap callback which can handle (at some extent) NOMMU 2) already defines dummy pgprot_noncached() for NOMMU build. c6x and frv stay untouched since they already have ARCH_NO_COHERENT_DMA_MMAP.

2017-06-30pinctrl: samsung: Remove bogus irq_[un]mask from resource managementThomas Gleixner
The irq chip callbacks irq_request/release_resources() have absolutely no business with masking and unmasking the irq. The core code unmasks the interrupt after complete setup and masks it before invoking irq_release_resources(). The unmask is actually harmful as it happens before the interrupt is completely initialized in __setup_irq(). Remove it.

2017-06-29sfc: fix attempt to translate invalid filter IDEdward Cree
When filter insertion fails with no rollback, we were trying to convert EFX_EF10_FILTER_ID_INVALID to an id to store in 'ids' (which is either vlan->uc or vlan->mc). This would WARN_ON_ONCE and then record a bogus filter ID of 0x1fff, neither of which is a good thing.

2017-06-29net/mlx4_en: Do not allocate redundant TX queues when TC is disabledInbar Karmy
Currently the number of TX queues that are allocated doesn't depend on the number of TCs, the module always loads with max num of UP per channel. In order to prevent the allocation of unnecessary memory, the module will load with minimum number of UPs per channel, and the user will be able to control the number of TX queues per channel by changing the number of TC to 8 using the tc command. The variable num_up will hold the information about the current number of UPs. Due to the change, needed to remove the lines that set the value of UP to be different than zero in the func "mlx4_en_select_queue", since now the num of TX queues that are allocated is only one per channel in default. In order not to force the UP to be zero in case of only one TC, added a condition before forcing it in the func "mlx4_en_fill_qp_context". Tested: After the module is loaded with minimum number of UP per channel, to increase num of TCs to 8, use: tc qdisc add dev ens8 root mqprio num_tc 8 In order to decrease the number of TCs to minimum number of UP per channel, use: tc qdisc del dev ens8 root Signed-off-by: Inbar Karmy <inbark@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Cc: Tarick Bedeir <tarick@google.com> Signed-off-by: David S.

2017-06-29net/mlx4_en: Add dynamic variable to hold the number of user priorities (UP)Inbar Karmy
Until this patch, the number of UPs was hard coded for eight. Replace this with a variable in struct "mlx4_en_port_profile". Currently, the variable will hold the maximum number of UP, as before. The patch creates an infrastructure to add an option for dynamic change of the actual number of TCs.

2017-06-29ibmvnic: Fix assignment of RX/TX IRQ'sThomas Falcon
The driver currently creates RX/TX queues during device probe, but assigns IRQ's to them during device open. On reset, however, IRQ's are assigned when resetting the queues. If there is a reset while the device is closed and the device is later opened, the driver will request IRQ's twice, causing the open to fail. This patch assigns the IRQ's in the ibmvnic_init function after the queues are reset or initialized, ensuring IRQ's are only requested once.
