2015-10-04dma: Add support to program MIC x100 status descriptiorsSiva Yerramreddy
The MIC X100 DMA engine has a special status descriptor which writes an 8 byte value to a destination location. This is used to signal completion of all DMA descriptors prior to the status descriptor. This patch add a new DMA engine API which enables updating a destination address with an 8 byte immediate data value.

2015-10-04debugfs: Pass bool pointer to debugfs_create_bool()Viresh Kumar
Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

2015-10-03tcp/dccp: add SLAB_DESTROY_BY_RCU flag for request socketsEric Dumazet
Before letting request sockets being put in TCP/DCCP regular ehash table, we need to add either : - SLAB_DESTROY_BY_RCU flag to their kmem_cache - add RCU grace period before freeing them. Since we carefully respected the SLAB_DESTROY_BY_RCU protocol like ESTABLISH and TIMEWAIT sockets, use it here. req_prot_init() being only used by TCP and DCCP, I did not add a new slab_flags into their rsk_prot, but reuse prot->slab_flags Since all reqsk_alloc() users are correctly dealing with a failure, add the __GFP_NOWARN flag to avoid traces under pressure.

2015-10-03phylib: Add phy_set_max_speed helperSimon Horman
Add a helper to allow ethernet drivers to limit the speed of a phy (that they are attached to). This mainly involves factoring out the business-end of of_set_phy_supported() and exporting a new symbol. This code seems to be open coded in several places, in several different variants. It is is envisaged that this will be used in situations where setting the "max-speed" property in DT is not appropriate, e.g. because the maximum speed is not a property of the phy hardware.

2015-10-03sched, bpf: add helper for retrieving routing realmsDaniel Borkmann
Using routing realms as part of the classifier is quite useful, it can be viewed as a tag for one or multiple routing entries (think of an analogy to net_cls cgroup for processes), set by user space routing daemons or via iproute2 as an indicator for traffic classifiers and later on processed in the eBPF program. Unlike actions, the classifier can inspect device flags and enable netif_keep_dst() if necessary. tc actions don't have that possibility, but in case people know what they are doing, it can be used from there as well (e.g. via devs that must keep dsts by design anyway). If a realm is set, the handler returns the non-zero realm. User space can set the full 32bit realm for the dst.

2015-10-03tcp: attach SYNACK messages to request sockets instead of listenerEric Dumazet
If a listen backlog is very big (to avoid syncookies), then the listener sk->sk_wmem_alloc is the main source of false sharing, as we need to touch it twice per SYNACK re-transmit and TX completion. (One SYN packet takes listener lock once, but up to 6 SYNACK are generated) By attaching the skb to the request socket, we remove this source of contention. Tested: listen(fd, 10485760); // single listener (no SO_REUSEPORT) 16 RX/TX queue NIC Sustain a SYNFLOOD attack of ~320,000 SYN per second, Sending ~1,400,000 SYNACK per second.

2015-10-03tcp/dccp: install syn_recv requests into ehash tableEric Dumazet
In this patch, we insert request sockets into TCP/DCCP regular ehash table (where ESTABLISHED and TIMEWAIT sockets are) instead of using the per listener hash table. ACK packets find SYN_RECV pseudo sockets without having to find and lock the listener. In nominal conditions, this halves pressure on listener lock. Note that this will allow for SO_REUSEPORT refinements, so that we can select a listener using cpu/numa affinities instead of the prior 'consistent hash', since only SYN packets will apply this selection logic. We will shrink listen_sock in the following patch to ease code review.

2015-10-02drivers: firmware: psci: add system suspend supportSudeep Holla
PSCI v1.0 introduces a new API called PSCI_SYSTEM_SUSPEND. This API provides the mechanism by which the calling OS can request entry into the deepest possible system sleep state. It meets all the necessary preconditions for entering suspend to RAM state in Linux. This patch adds support for PSCI_SYSTEM_SUSPEND in psci firmware and registers a psci system suspend operation to implement the suspend-to-RAM(s2r) in a generic way on all the platforms implementing PSCI.
