2018-12-18pinctrl: sh-pfc: r8a77990: Fix MOD_SEL0 SEL_I2C1 field widthGeert Uytterhoeven
The SEL_I2C1 (MOD_SEL0[21:20]) field in Module Select Register 0 has a width of 2 bits, i.e. it allows programming one out of 4 different configurations. However, the MOD_SEL0_21_20 macro contains 8 values instead of 4, overflowing into the subsequent fields in the register, and thus breaking the configuration of the latter. Fix this by dropping the bogus last 4 values, including the non-existent SEL_I2C1_4 configuration.

2018-12-18ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idleRafael J. Wysocki
There are systems in which non-wakeup GPEs fire during the "noirq" suspend stage of suspending devices and that effectively prevents the system that tries to suspend to idle from entering any low-power state at all. If the offending GPE fires regularly and often enough, the system appears to be suspended, but in fact it is in a tight loop over "noirq" suspend and "noirq" resume of devices all the time. To prevent that from happening, disable all non-wakeup GPEs except for the EC GPE for suspend-to-idle (the EC GPE is special, because on some systems it has to be enabled for power button wakeup events to be generated as expected).

2018-12-17nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-17net: dccp: initialize (addr,port) listening hashtablePeter Oskolkov
Commit d9fbc7f6431f "net: tcp: prefer listeners bound to an address" removes port-only listener lookups. This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. V2 changes: marked inet_hashinfo2_init as an exported symbol so that DCCP compiles when configured as a module.

2018-12-17bnxt_en: Store the maximum NQs available on the PF.Michael Chan
The PF has a pool of NQs and MSIX vectors assigned to it based on NVRAM configurations. The number of usable MSIX vectors on the PF is the minimum of the NQs and MSIX vectors. Any excess NQs without associated MSIX may be used for the VFs, so we need to store this max_nqs value. max_nqs minus the NQs used by the PF will be the available NQs for the VFs.

2018-12-17MIPS: Remove struct mm_context_t fp_mode_switching fieldPaul Burton
The fp_mode_switching field in struct mm_context_t was left unused by commit 8c8d953c2800 ("MIPS: Schedule on CPUs we need to lose FPU for a mode switch") in v4.19, with nothing modifying its value & nothing waiting on it having any particular value after that commit. Remove the unused field & the one remaining reference to it. Signed-off-by: Paul Burton <paul.burton@mips.com>
2018-12-17fou: Prevent unbounded recursion in GUE error handlerStefano Brivio
Handling exceptions for direct UDP encapsulation in GUE (that is, UDP-in-UDP) leads to unbounded recursion in the GUE exception handler, syzbot reported. While draft-ietf-intarea-gue-06 doesn't explicitly forbid direct encapsulation of UDP in GUE, it probably doesn't make sense to set up GUE this way, and it's currently not even possible to configure this. Skip exception handling if the GUE proto/ctype field is set to the UDP protocol number. Should we need to handle exceptions for UDP-in-GUE one day, we might need to either explicitly set a bound for recursion, or implement a special iterative handling for these cases.

2018-12-17blk-mq: enable IO poll if .nr_queues of type poll > 0Ming Lei
The queue mapping of type poll only exists when set->map[HCTX_TYPE_POLL].nr_queues is bigger than zero, so enhance the constraint by checking .nr_queues of type poll before enabling IO poll. Otherwise IO race & timeout can be observed when running block/007.

2018-12-17blk-mq: change blk_mq_queue_busy() to blk_mq_queue_inflight()Jens Axboe
There's a single user of this function, dm, and dm just wants to check if IO is inflight, not that it's just allocated. This fixes a hang with srp/002 in blktests with dm, where it tries to suspend but waits for inflight IO to finish first. As it checks for just allocated requests, this fails.
