The macb driver only handle PHY description through platform_data (macb_platform_data). Thus, when using dt you cannot define phy properties like phy address or phy irq pin. This patch makes use of the of_mdiobus_register to add support for phy device definition using dt. A fallback to the autoscan procedure is added in case there is no phy devices defined in dt.

Fix the issue with improper counting number of flying bio requests for BIO_EOPNOTSUPP error detection case. The sb_nbio must be incremented exactly the same number of times as complete() function was called (or will be called) because nilfs_segbuf_wait() will call wail_for_completion() for the number of times set to sb_nbio: do { wait_for_completion(&segbuf->sb_bio_event); } while (--segbuf->sb_nbio > 0); Two functions complete() and wait_for_completion() must be called the same number of times for the same sb_bio_event.

2013-08-23drivers/platform/olpc/olpc-ec.c: initialise earlierDaniel Drake1-1/+1
Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake <dsd@laptop.org> Cc: Andres Salomon <dilinger@queued.net> Cc: Paul Fox <pgf@laptop.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-08-22tcp: increase throughput when reordering is highYuchung Cheng1-12/+20
The stack currently detects reordering and avoid spurious retransmission very well. However the throughput is sub-optimal under high reordering because cwnd is increased only if the data is deliverd in order. I.e., FLAG_DATA_ACKED check in tcp_ack(). The more packet are reordered the worse the throughput is. Therefore when reordering is proven high, cwnd should advance whenever the data is delivered regardless of its ordering. If reordering is low, conservatively advance cwnd only on ordered deliveries in Open state, and retain cwnd in Disordered state (RFC5681). Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms to 55ms (for reordering effect). This change increases TCP throughput by 20 - 25% to near bottleneck BW. A special case is the stretched ACK with new SACK and/or ECE mark. For example, a receiver may receive an out of order or ECN packet with unacked data buffered because of LRO or delayed ACK. The principle on such an ACK is to advance cwnd on the cummulative acked part first, then reduce cwnd in tcp_fastretrans_alert().

This reverts commit df54d6fa54275ce59660453e29d1228c2b45a826. The commit isn't necessarily wrong, but because it recalculates the random mmap_base every time, it seems to confuse user memory allocators that expect contiguous mmap allocations even when the mmap address isn't specified. In particular, the MATLAB Java runtime seems to be unhappy. See https://bugzilla.kernel.org/show_bug.cgi?id=60774 So we'll want to apply the random offset only once, and Radu has a patch for that.

2013-08-22igb: Expose RSS indirection table for ethtoolLaura Mihaela Vasilescu3-21/+97
This patch adds the ethtool callbacks necessary to change the RETA indirection table from userspace. In order to achieve this, we add the indirection table field (rss_indir_tbl) in the board specific data structure (struct igb_adapter) to preserve the values across hardware resets. The indirection table must be initialized with default values in the following cases: * at module init time * when the number of RX queues changes. For this reason we add a new field (rss_indir_tbl_init) in igb_adapter that keeps track of the number of RX queues. Whenever the number of RX queues changes, the rss_indir_tbl is modified and initialized with default values. The rss_indir_tbl_init is updated accordingly.
