2013-07-27ARM: Fix sorting of machine- initializersRussell King
So, there's a comment I put at the top of this, which people seem to fail to read. So let's fix it for them instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-07-26serial: arc_uart: Fix module aliasAxel Lin
Platform drivers use "platform:" prefix in module alias. Also use DRIVER_NAME in MODULE_ALIAS to make module autoloading work.

2013-07-26tty_port: Fix refcounting leak in tty_port_tty_hangup()Gianluca Anzolin
The function tty_port_tty_hangup() could leak a reference to the tty_struct: struct tty_struct *tty = tty_port_tty_get(port); if (tty && (!check_clocal || !C_CLOCAL(tty))) { tty_hangup(tty); tty_kref_put(tty); } If tty != NULL and the second condition is false we never call tty_kref_put and the reference is leaked. Fix by always calling tty_kref_put() which accepts a NULL argument. The patch fixes a regression introduced by commit aa27a094.

2013-07-26serial/mxs-auart: increase time to wait for transmitter to become idleUwe Kleine-König
Without this patch the driver waits ~1 ms for the UART to become idle. At 115200n8 this time is (theoretically) enough to transfer 11.5 characters (= 115200 bits/s / (10 Bits/char) * 1ms). As the mxs-auart has a fifo size of 16 characters the clock is gated too early. The problem is worse for lower baud rates. This only happens to really shut down the transmitter in the middle of a transfer if /dev/ttyAPPx isn't opened in userspace (e.g. by a getty) but was at least once (because the bootloader doesn't disable the transmitter). So increase the timeout to 20 ms which should be enough for 9600n8, too. Moreover skip gating the clock if the timeout is elapsed.

2013-07-26serial/mxs-auart: fix race condition in interrupt handlerUwe Kleine-König
The handler needs to ack the pending events before actually handling them. Otherwise a new event might come in after it it considered non-pending or handled and is acked then without being handled. So this event is only noticed when the next interrupt happens. Without this patch an i.MX28 based machine running an rt-patched kernel regularly hangs during boot.

2013-07-26atl1c: Fix misuse of netdev_alloc_skb in refilling rx ringNeil Horman
atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no guarantees about the suitability of the memory for use in DMA. As a result we've gotten reports of atl1c drivers occasionally hanging and needing to be reset: https://bugzilla.kernel.org/show_bug.cgi?id=54021 Fix this by modifying the call to use the internal version __netdev_alloc_skb, where you can set the gfp_mask explicitly to include GFP_DMA.

Pull qxl drm fixes from Dave Airlie: "Okay as I warned, the qxl driver was running a bit free and loose with its ttm object reservations and the new lockdep enabled reservation tracking shone a bright light into it, it also with the new reservations mutexes hits a possible deadlock during boot. The first patch is a real fix to render the console correctly as the driver used to just drop irq renderering as too hard, this also fixes a sleeping while atomic warning. The other two patches are the big ugly ones that redo how the driver allocates objects and reserves them and makes things all work properly, I've tested this in a VM, and compared to the current code which hits a lockdep warning and the sleep while atomic warning before failing.

2013-07-26usbnet: do not pretend to support SG/TSOEric Dumazet
usbnet doesn't support yet SG, so drivers should not advertise SG or TSO capabilities, as they allow TCP stack to build large TSO packets that need to be linearized and might use order-5 pages. This adds an extra copy overhead and possible allocation failures. Current code ignore skb_linearize() return code so crashes are even possible. Best is to not pretend SG/TSO is supported, and add this again when/if usbnet really supports SG for devices who could get a performance gain.

2013-07-26ext4: make sure group number is bumped after a inode allocation raceTheodore Ts'o
When we try to allocate an inode, and there is a race between two CPU's trying to grab the same inode, _and_ this inode is the last free inode in the block group, make sure the group number is bumped before we continue searching the rest of the block groups. Otherwise, we end up searching the current block group twice, and we end up skipping searching the last block group. So in the unlikely situation where almost all of the inodes are allocated, it's possible that we will return ENOSPC even though there might be free inodes in that last block group.

2013-07-26[media] hdpvr: fix iteration over uninitialized lists in hdpvr_probe()Alexey Khoroshilov
free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(), but if something bad happens before that, error handling code calls hdpvr_delete(), which contains iteration over the lists (via hdpvr_free_buffers()). The patch moves the lists initialization to the beginning and by the way fixes goto label in error handling of registering videodev. Found by Linux Driver Verification project (linuxtesting.org).

2013-07-26PCI: Retry allocation of only the resource type that failedYinghai Lu
Ben Herrenschmidt reported the following problem: - The bus has space for all desired MMIO resources, including optional space for SR-IOV devices - We attempt to allocate I/O port space, but it fails because the bus has no I/O space - Because of the I/O allocation failure, we retry MMIO allocation, requesting only the required space, without the optional SR-IOV space This means we don't allocate the optional SR-IOV space, even though we could. This is related to 0c5be0cb0e ("PCI: Retry on IORESOURCE_IO type allocations"). This patch changes how we handle allocation failures. We will now retry allocation of only the resource type that failed. If MMIO allocation fails, we'll retry only MMIO allocation. If I/O port allocation fails, we'll retry only I/O port allocation.
