2012-02-08nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments()Xi Wang
nsegs is read from userspace. Limit its value and avoid overflowing nsegs * sizeof(__u64) in the subsequent call to memdup_user().

2012-02-08gro: more generic L2 header checkEric Dumazet
Shlomo Pongratz reported GRO L2 header check was suited for Ethernet only, and failed on IB/ipoib traffic. He provided a patch faking a zeroed header to let GRO aggregates frames. Roland Dreier, Herbert Xu, and others suggested we change GRO L2 header check to be more generic, ie not assuming L2 header is 14 bytes, but taking into account hard_header_len. __napi_gro_receive() has special handling for the common case (Ethernet) to avoid a memcmp() call and use an inline optimized function instead.

2012-02-08IPoIB: Stop lying about hard_header_len and use skb->cb to stash LL addressesRoland Dreier
Commit a0417fa3a18a ("net: Make qdisc_skb_cb upper size bound explicit.") made it possible for a netdev driver to use skb->cb between its header_ops.create method and its .ndo_start_xmit method. Use this in ipoib_hard_header() to stash away the LL address (GID + QPN), instead of the "ipoib_pseudoheader" hack. This allows IPoIB to stop lying about its hard_header_len, which will let us fix the L2 check for GRO. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: David S.

Commit 9bef3d4197379a995fa80f81950bbbf8d32e9e8b "serial: group all the 8250 related code together" inadvertently swept up the m32r driver in the move, because it had comments mentioning 8250 registers within it.

2012-02-08zcache: Set SWIZ_BITS to 8 to reduce tmem bucket lock contention.Dan Magenheimer
SWIZ_BITS > 8 results in a much larger number of "tmem_obj" allocations, likely one per page-placed-in-frontswap. The tmem_obj is not huge (roughly 100 bytes), but it is large enough to add a not-insignificant memory overhead to zcache. The SWIZ_BITS=8 will get roughly the same lock contention without the space wastage. The effect of SWIZ_BITS can be thought of as "2^SWIZ_BITS is the number of unique oids that be generated" (This concept is limited to frontswap's use of tmem).

Add support in framebuffer objects for other color formats and multi- planar YUV (NV12). Since this requires changing the API between the plane and fb for getting scanout information (paddr, etc), take advantage of the opportunity and put in place a way to allow fb's to be unpinned when they are not being scanned out. Now, before start of scanout the plane calls omap_framebuffer_pin() which takes care to pin all the backing bo's, then omap_framebuffer_update_scanout() however many times to update the scanout address(es), etc, and then when finished omap_framebuffer_unpin().

2012-02-08bio: don't overflow in bio_get_nr_vecs()Kent Overstreet
There were two places bio_get_nr_vecs() could overflow: First, it did a left shift to convert from sectors to bytes immediately before dividing by PAGE_SIZE. If PAGE_SIZE ever was less than 512 a great many things would break, so dividing by PAGE_SIZE >> 9 is safe and will generate smaller code too. The nastier overflow was in the DIV_ROUND_UP() (that's what the code was effectively doing, anyways). If n + d overflowed, the whole thing would return 0 which breaks things rather effectively. bio_get_nr_vecs() doesn't claim to give an exact value anyways, so the DIV_ROUND_UP() is silly; we could do a straight divide except if a device's queue_max_sectors was less than PAGE_SIZE we'd return 0. So we just add 1; this should always be safe - things will break badly if bio_get_nr_vecs() returns > BIO_MAX_PAGES (bio_alloc() will suddenly start failing) but it's queue_max_segments that must guard against this, if queue_max_sectors is preventing this from happen things are going to explode on architectures with different PAGE_SIZE.

2012-02-08bsg: fix sysfs link remove warningStanislaw Gruszka
We create "bsg" link if q->kobj.sd is not NULL, so remove it only when the same condition is true.

2012-02-08ALSA: oxygen, virtuoso: fix exchanged L/R volumes of aux and CD inputsClemens Ladisch
The driver accidentally exchanged the left/right fields for stereo AC'97 mixer registers. This affected only the aux and CD inputs because the line input bypasses the AC'97 codec and the mic input is mono; cards without AC'97 (Xonar DS/DG/HDAV Slim, HG2PCI, HiFier) were not affected.
