    Pull driver core updates from Greg Kroah-Hartman:
    "Here's the driver core, and other driver subsystems, pull request for
    the 3.5-rc1 merge window.

    Outside of a few minor driver core changes, we ended up with the
    following different subsystem and core changes as well, due to
    interdependancies on the driver core:
    - hyperv driver updates
    - drivers/memory being created and some drivers moved into it
    - extcon driver subsystem created out of the old Android staging
    switch driver code
    - dynamic debug updates
    - printk rework, and /dev/kmsg changes

    All of this has been tested in the linux-next releases for a few weeks
    with no reported problems.

    Fix up conflicts in drivers/extcon/extcon-max8997.c where git noticed
    that a patch to the deleted drivers/misc/max8997-muic.c driver needs to
    be applied to this one.

    This function returns negative error codes, but because the type is u16
    they get truncated into positive numbers. It doesn't look like the
    callers care, but we should fix it anyway as a cleanup.

  • 33be96e47   net/hyperv: Add flow control based on hi/low watermark ... Browse Code »

    In the existing code, we only stop queue when the ringbuffer is full,
    so the current packet has to be dropped or retried from upper layer.

    This patch stops the tx queue when available ringbuffer is below
    the low watermark. So the ringbuffer still has small amount of space
    available for the current packet. This will reduce the overhead of
    retries on sending.

  • 14c1bf8a8   drivers: hv: Increase the number of VCPUs supported in the guest ... Browse Code »

    The current code arbirarily limited the number of CPUs the guest could have.
    Change that so that we can support the maximum number of CPUs the guest can
    support. While we use NR_CPUS to size the per-cpu state all we are allocating
    based on NR_CPUS are the pointers to per-cpu state that will be allocatted in
    the context of the initializing CPU. This patch triggers a checkpatch warning
    for the usage of NR_CPU and since all we are allocating a couple of pointers
    per CPU, it should be ok.

  • 8f257a142   Drivers:hv: Fix a bug in vmbus_driver_unregister() ... Browse Code »

    The function vmbus_exists() was introduced recently to deal with cases where
    the vmbus driver failed to initialize and yet other Hyper-V drivers attempted
    to register with the vmbus bus driver. This patch introduced a bug where
    vmbus_driver_unregister() would fail to unregister the driver. This patch
    fixes the problem.

  • cf6a2eacb   drivers: hv: Don't OOPS when you cannot init vmbus ... Browse Code »

    The hv vmbus driver was causing an OOPS since it was trying to register drivers
    on top of the bus even if initialization of the bus has failed for some
    reason (such as the odd chance someone would run a hv enabled kernel in a
    non-hv environment).

  • 0720a06a7   NLS: improve UTF8 -> UTF16 string conversion routine ... Browse Code »

    The utf8s_to_utf16s conversion routine needs to be improved. Unlike
    its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
    the maximum length of the output buffer or the endianness of its
    16-bit output.

    This patch (as1501) adds the two missing arguments, and adjusts the
    only two places in the kernel where the function is called. A
    follow-on patch will add a third caller that does utilize the new
    capabilities.

    The two conversion routines are still annoyingly inconsistent in the
    way they handle invalid byte combinations. But that's a subject for a
    different patch.
