    This fixes an erroneous use of LSB first in the U300 machine, the
    PL022 used in U300 is a standard ARM core that doesn't support this
    bit so it should never have been set.

    dwmw2 authored Jean Delvare committed
    It's poor form to keep driver state in global variables rather than
    per-instance. It never really mattered in practice when there was only
    one controller on the chipset, but the latest chipsets do have more
    than one controller, so now we care.

    locks: let the caller free file_lock on ->setlease failure

    Christoph Hellwig authored torvalds committed
    The caller allocated it, the caller should free it.
    
    The only issue so far is that we could change the flp pointer even on an
    error return if the fl_change callback failed.  But we can simply move
    the flp assignment after the fl_change invocation, as the callers don't
    care about the flp return value if the setlease call failed.

        Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)
    
    As pointed out by Kerstin Jonsson <kerstin.jonsson@ericsson.com>, this
    is due to CONFIG_32BIT not being defined, so the initramfs size field is
    done as a 64-bit quad.  On little-endian (like x86) this doesn matter,
    but on a big-endian machine the 32-bit reads will see the (zero) high
    bits.
    
    Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
    all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
    which should be defined on all 64-bit arches.

    nfsd4: initialize delegation pointer to lease

    J. Bruce Fields authored torvalds committed
    The NFSv4 server was initializing the dp->dl_flock pointer by the
    somewhat ridiculous method of a locks_copy_lock callback.
    
    Now that setlease uses the passed-in lock instead of doing a copy,
    dl_flock no longer gets set, resulting in the lock leaking on delegation
    release, and later possible hangs (among other problems).
    
    So, initialize dl_flock and get rid of the callback.

    locks: prevent ENOMEM on lease unlock

    J. Bruce Fields authored torvalds committed
    Removing a lock shouldn't require any allocations; a failure due to
    ENOMEM leaves the caller with a choice between retrying or giving up and
    leaking an unused lease.
    
    Next we should split the other lease calls into add and delete cases.
    I wanted to start with just the bugfix.

    RDS: Let rds_message_alloc_sgs() return NULL

    Andy Grover authored davem330 committed
    Even with the previous fix, we still are reading the iovecs once
    to determine SGs needed, and then again later on. Preallocating
    space for sg lists as part of rds_message seemed like a good idea
    but it might be better to not do this. While working to redo that
    code, this patch attempts to protect against userspace rewriting
    the rds_iovec array between the first and second accesses.
    
    The consequences of this would be either a too-small or too-large
    sg list array. Too large is not an issue. This patch changes all
    callers of message_alloc_sgs to handle running out of preallocated
    sgs, and fail gracefully.

    RDS: Copy rds_iovecs into kernel memory instead of rereading from use…

    Andy Grover authored davem330 committed
    …rspace
    
    Change rds_rdma_pages to take a passed-in rds_iovec array instead
    of doing copy_from_user itself.
    
    Change rds_cmsg_rdma_args to copy rds_iovec array once only. This
    eliminates the possibility of userspace changing it after our
    sanity checks.
    
    Implement stack-based storage for small numbers of iovecs, based
    on net/socket.c, to save an alloc in the extremely common case.
    
    Although this patch reduces iovec copies in cmsg_rdma_args to 1,
    we still do another one in rds_rdma_extra_size. Getting rid of
    that one will be trickier, so it'll be a separate patch.

    net: fix rds_iovec page count overflow

    torvalds authored davem330 committed
    As reported by Thomas Pollet, the rdma page counting can overflow.  We
    get the rdma sizes in 64-bit unsigned entities, but then limit it to
    UINT_MAX bytes and shift them down to pages (so with a possible "+1" for
    an unaligned address).
    
    So each individual page count fits comfortably in an 'unsigned int' (not
    even close to overflowing into signed), but as they are added up, they
    might end up resulting in a signed return value. Which would be wrong.
    
    Catch the case of tot_pages turning negative, and return the appropriate
    error code.
