2013-01-22ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructuresBarry Song
this patch adds tick timer, smp entries and generic DT machine for SiRFmarco dual-core SMP chips. with the added marco, we change the defconfig, using the same defconfig, we get a zImage which can work on both prima2 and marco.

2013-01-22ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for MarcoBarry Song
in Marco, we will use GIC. this patch prepares the handle_irq for prima2 to avoid the compiling errors since we want only one defconfig and zImage for both prima2 and marco that means we will need handle_irq for both. Signed-off-by: Baohua Song <Baohua.Song@csr.com>

2013-01-22ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marcoBarry Song
Marco timer has different timer IP with prima2, so rename the current timer to timer-prima2 so that we can add timer-marco. at the same time, if we don't find prima2 timer node in dt, don't panic the system as we will make prima2 and marco use same kernel image.

2013-01-22mfd: tc3589x: Use simple irqdomainLinus Walleij
This fixes a regression in the TC3589x driver introduced in commit 15e27b1088245a2de3b7d09d39cd209212eb16af "mfd: Provide the tc3589x with its own IRQ domain" If a system with a TC3589x expander is booted and a base IRQ is passed from platform data, a legacy domain will be used. However, since the Ux500 is now switched to use SPARSE_IRQ, no descriptors get allocated on-the-fly, and we get a crash. Fix this by switching to using the simple irqdomain that will handle this uniformly and also allocates descriptors explicitly. Also fix two small whitespace errors in the vicinity while we're at it.

2013-01-22f2fs: avoid issuing small bios due to several dirty node pagesJaegeuk Kim
If some small bios of dirty node pages are supposed to be issued during the sequential data writes, there-in well-produced consecutive data bios are able to be split by the small node bios, resulting in performance degradation. So, let's collect a number of dirty node pages until reaching a threshold. And, by default, I set the threshold as 2MB, a segment size. This improves sequential write performance on i5, 512GB SSD (830 w/ SATA2) as follows.

2013-01-22mfd: db8500-prcmu: Fix irqdomain usageLinus Walleij
This fixes two issues with the DB8500 PRCMU irqdomain: - You have to state the irq base 0 to get a linear domain for the DT case from irq_domain_add_simple() - The irqdomain was not used to translate the initial irq request using irq_create_mapping() making the linear case fail as it was lacking a proper descriptor.

2013-01-21net: cdc_mbim: send ZLP after max sized NTBsBjørn Mork
We normally avoid sending ZLPs by padding NTBs with a zero byte if the NTB is shorter than dwNtbOutMaxSize, resulting in a short USB packet instead of a ZLP. But in the case where the NTB length is exactly dwNtbOutMaxSize and this is an exact multiplum of wMaxPacketSize, then we must send a ZLP. This fixes an issue seen on a Sierra Wireless MC7710 device where the transmission would fail whenever we ended up padding the NTBs to max size.

2013-01-21net: cdc_ncm: workaround for missing CDC UnionBjørn Mork
Adding support for the MBIM mode in some Sierra Wireless devices. Some Sierra Wireless firmwares support CDC MBIM but have no CDC Union funtional descriptor. This violates the MBIM specification, but we can easily work around the bug by looking at the Interface Association Descriptor instead. This is most likely what Windows uses too, which explains how the firmware bug has gone unnoticed until now. This change will not affect any currently supported device conforming to the NCM or MBIM specifications, as they must have the CDC Union descriptor.
