2012-08-07xhci: Increase reset timeout for Renesas 720201 host.Sarah Sharp
The NEC/Renesas 720201 xHCI host controller does not complete its reset within 250 milliseconds. In fact, it takes about 9 seconds to reset the host controller, and 1 second for the host to be ready for doorbell rings. Extend the reset and CNR polling timeout to 10 seconds each. This patch should be backported to kernels as old as 2.6.31, that contain the commit 66d4eadd8d067269ea8fead1a50fe87c2979a80d "USB: xhci: BIOS handoff and HW initialization."

2012-08-07usb: musb: use DMA mode 1 whenever possibleRoger Quadros
Do not rely on any hints from gadget drivers and use DMA mode 1 whenever we expect data of at least the endpoint's packet size and have not yet received a short packet. The last packet if short is always transferred using DMA mode 0. This patch fixes USB throughput issues in mass storage mode for host to device transfers.

2012-08-03usb: dwc3: ep0: move DATA phase away from on-demandFelipe Balbi
We uncovered a limitation of this core WRT to the Link Layer Compliance Suite's TD7.06. On that test, host will start a GetDescriptor(DEVICE) standard request, but it will do so only on the SETUP phase, meaning there will *NOT* be any DATA or STATUS phases. The idea of the test is to verify robustness of the IP WRT framing errors, so the test will send a sequence of different SETUP_DPs each with a different framing error and the Suite expects us to be able to receive all SETUP_DPs with no timeouts. This core, has the ability to tell us which phase the host is expecting before we start it. Whenever we receive a TP or DP when no transfers are cached on the internal IP's caches, the IP will generate a XferNotReady event with status informing us (in case of physical ep0/ep1) if it's related to DATA or STATUS phases - SETUP phase is expected to be prestarted. Because we're always waiting for XferNotReady events for DATA and STATUS phases, we will never be able to know that the Host wants to start another SETUP phase instead, which will render us "not compliant" with TD7.06. In order to "fix" the problem we must not rely on XferNotReady events for the DATA phase and try to always pre-start DATA transfers on physical endpoints 0 and 1. If host goes back to SETUP phase from DATA phase we will receive a XferComplete for that phase with TRB's status set to SETUP_PENDING, which is only useful for printing a debugging log as the core expects us to still go through to the STATUS phase, initiate a CONTROL_STATUS TRB just so it completes right away and, only then, we go back to the pending SETUP phase. SNPS has decided to modify the programming model of the core so that on-demand DATA phases will not be supported anymore. Note that this limitation does not affect 2-stage transfers, meaning that if TD7.06 would start a 2-stage transfer instead of a 3-stage transfer, we would receive a "fake" XferNotReady(STATUS) which would complete right after being initiated with SETUP_PENDING status. Other endpoints are also not affected, so we can still use on-demand transfers on Bulk/Isoc/Interrupt endpoints. Signed-off-by: Felipe Balbi <balbi@ti.com>

2012-07-31netvm: propagate page->pfmemalloc from skb_alloc_page to skbMel Gorman
The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function).

Pull networking changes from David S Miller: 1) Remove the ipv4 routing cache. Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer. Whereas the existing BQL (Byte Queue Limits) limits the pkt_sched --> netdevice queuing levels, this controls the TCP --> pkt_sched queueing levels. From Eric Dumazet. 11) Reduce the number of get_page/put_page ops done on SKB fragments, from Alexander Duyck. 12) Implement protection against blind resets in TCP (RFC 5961), from Eric Dumazet. 13) Support the client side of TCP Fast Open, basically the ability to send data in the SYN exchange, from Yuchung Cheng. Basically, the sender queues up data with a sendmsg() call using MSG_FASTOPEN, then they do the connect() which emits the queued up fastopen data. 14) Avoid all the problems we get into in TCP when timers or PMTU events hit a locked socket. The TCP Small Queues changes added a tcp_release_cb() that allows us to queue work up to the release_sock() caller, and that's what we use here too. From Eric Dumazet. 15) Zero copy on TX support for TUN driver, from Michael S.
