    initramfs: Fix initramfs size for 32-bit arches

    Commit ffe8018c3424 ("initramfs: fix initramfs size calculation") broke
    32-bit big-endian arches like (on ARAnyM):

        VFS: Cannot open root device "hda1" or unknown-block(3,1)
        Please append a correct "root=" boot option; here are the available partitions:
        fe80         1059408 nfhd8  (driver?)
          fe81          921600 nfhd8p1 00000000-0000-0000-0000-000000000nfhd8p1
          fe82          137807 nfhd8p2 00000000-0000-0000-0000-000000000nfhd8p2
        0200            3280 fd0  (driver?)
        0201            3280 fd1  (driver?)
        0300         1059408 hda  driver: ide-gd
          0301          921600 hda1 00000000-0000-0000-0000-000000000hda1
          0302          137807 hda2 00000000-0000-0000-0000-000000000hda2
        Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)

    As pointed out by Kerstin Jonsson <kerstin.jonsson <at> 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.

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

    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.

    [SCSI] zfcp: Fix adapter activation on link down

    If an exchange config is executed while the local link is down, the
    request succeeds but the returned data is incomplete.  Proceeding with
    the adapter activation is leading to an unpredictable behaviour (e.g.
    kernel panic) caused by invalid values.  In such a scenario the
    recommended ERP is to retry the action and wait for a link up event.
    If the issue persists the activation has to fail.
