Merge tag 'v3.2-rc7' into staging/for_v3.3
Linux 3.2-rc7 * tag 'v3.2-rc7': (1304 commits) Linux 3.2-rc7 netfilter: xt_connbytes: handle negation correctly Btrfs: call d_instantiate after all ops are setup Btrfs: fix worker lock misuse in find_worker net: relax rcvbuf limits rps: fix insufficient bounds checking in store_rps_dev_flow_table_cnt() net: introduce DST_NOPEER dst flag mqprio: Avoid panic if no options are provided bridge: provide a mtu() method for fake_dst_ops md/bitmap: It is OK to clear bits during recovery. md: don't give up looking for spares on first failure-to-add md/raid5: ensure correct assessment of drives during degraded reshape. md/linear: fix hot-add of devices to linear arrays. sparc64: Fix MSIQ HV call ordering in pci_sun4v_msiq_build_irq(). pata_of_platform: Add missing CONFIG_OF_IRQ dependency. ipv4: using prefetch requires including prefetch.h VFS: Fix race between CPU hotplug and lglocks vfs: __read_cache_page should use gfp argument rather than GFP_KERNEL USB: Fix usb/isp1760 build on sparc net: Add a flow_cache_flush_deferred function ...
