2012-12-11Merge tag 'char-misc-3.8-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull Char/Misc driver merge from Greg Kroah-Hartman: "Here is the "big" char/misc driver patches for 3.8-rc1.

Note, some MFD drivers got added through this tree, and they are also coming in through the "real" MFD tree as well, due to some major mis-communication between me and the different developers.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg Kroah-Hartman: "Here's the large driver core updates for 3.8-rc1. The biggest thing here is the various __dev* marking removals. This is going to be a pain for the merge with different subsystem trees, I know, but all of the patches included here have been ACKed by their various subsystem maintainers, as they wanted them to go through here. If this is too much of a pain, I can pull all of them out of this tree and just send you one with the other fixes/updates and then, after 3.8-rc1 is out, do the rest of the removals to ensure we catch them all, it's up to you. The merges should all be trivial, and Stephen has been doing them all in linux-next for a few weeks now quite easily. Other than the __dev* marking removals, there's nothing major here, some firmware loading updates and other minor things in the driver core.

2012-12-11drivers: cma: represent physical addresses as phys_addr_tVitaly Andrianov
This commit changes the CMA early initialization code to use phys_addr_t for representing physical addresses instead of unsigned long. Without this change, among other things, dma_declare_contiguous() simply discards any memory regions whose address is not representable as unsigned long. This is a problem on 32-bit PAE machines where unsigned long is 32-bit but physical address space is larger.

2012-12-10clk: introduce optional disable_unused callbackMike Turquette
Some gate clocks have special needs which must be handled during the disable-unused clocks sequence. These needs might be driven by software due to the fact that we're disabling a clock outside of the normal clk_disable path and a clk's enable_count will not be accurate. On the other hand a specific hardware programming sequence might need to be followed for this corner case. This change is needed for the upcoming OMAP port to the common clock framework. Specifically, it is undesirable to treat the disable-unused path identically to the normal clk_disable path since other software layers are involved. In this case OMAP's clockdomain code throws WARNs and bails early due to the clock's enable_count being set to zero. A custom callback mitigates this problem nicely.

2012-12-10Revert "revert "Revert "mm: remove __GFP_NO_KSWAPD""" and associated damageLinus Torvalds
This reverts commits a50915394f1fc02c2861d3b7ce7014788aa5066e and d7c3b937bdf45f0b844400b7bf6fd3ed50bac604. This is a revert of a revert of a revert. In addition, it reverts the even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the original commits in linux-next. It turns out that the original patch really was bogus, and that the original revert was the correct thing to do after all. We thought we had fixed the problem, and then reverted the revert, but the problem really is fundamental: waking up kswapd simply isn't the right thing to do, and direct reclaim sometimes simply _is_ the right thing to do. When certain allocations fail, we simply should try some direct reclaim, and if that fails, fail the allocation. That's the right thing to do for THP allocations, which can easily fail, and the GPU allocations want to do that too. So starting kswapd is sometimes simply wrong, and removing the flag that said "don't start kswapd" was a mistake. Let's hope we never revisit this mistake again - and certainly not this many times ;) Acked-by: Mel Gorman <mgorman@suse.de> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Rik van Riel <riel@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Technologic Systems TS-5500 provides digital I/O lines exposed through pin blocks. On this platform, there are three of them, named DIO1, DIO2 and LCD port, that may be used as a DIO block. The TS-5500 pin blocks are described in the product's wiki: http://wiki.embeddedarm.com/wiki/TS-5500#Digital_I.2FO This driver is not limited to the TS-5500 blocks.

2012-12-07net: gro: fix possible panic in skb_gro_receive()Eric Dumazet
commit 2e71a6f8084e (net: gro: selective flush of packets) added a bug for skbs using frag_list. This part of the GRO stack is rarely used, as it needs skb not using a page fragment for their skb->head. Most drivers do use a page fragment, but some of them use GFP_KERNEL allocations for the initial fill of their RX ring buffer. napi_gro_flush() overwrite skb->prev that was used for these skb to point to the last skb in frag_list. Fix this using a separate field in struct napi_gro_cb to point to the last fragment. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-12-07tcp: bug fix Fast Open client retransmissionYuchung Cheng
If SYN-ACK partially acks SYN-data, the client retransmits the remaining data by tcp_retransmit_skb(). This increments lost recovery state variables like tp->retrans_out in Open state. If loss recovery happens before the retransmission is acked, it triggers the WARN_ON check in tcp_fastretrans_alert(). For example: the client sends SYN-data, gets SYN-ACK acking only ISN, retransmits data, sends another 4 data packets and get 3 dupacks. Since the retransmission is not caused by network drop it should not update the recovery state variables. Further the server may return a smaller MSS than the cached MSS used for SYN-data, so the retranmission needs a loop. Otherwise some data will not be retransmitted until timeout or other loss recovery events.

2012-12-06tmpfs: fix shared mempolicy leakMel Gorman
This fixes a regression in 3.7-rc, which has since gone into stable. Commit 00442ad04a5e ("mempolicy: fix a memory corruption by refcount imbalance in alloc_pages_vma()") changed get_vma_policy() to raise the refcount on a shmem shared mempolicy; whereas shmem_alloc_page() went on expecting alloc_page_vma() to drop the refcount it had acquired. This deserves a rework: but for now fix the leak in shmem_alloc_page(). Hugh: shmem_swapin() did not need a fix, but surely it's clearer to use the same refcounting there as in shmem_alloc_page(), delete its onstack mempolicy, and the strange mpol_cond_copy() and __mpol_cond_copy() - those were invented to let swapin_readahead() make an unknown number of calls to alloc_pages_vma() with one mempolicy; but since 00442ad04a5e, alloc_pages_vma() has kept refcount in balance, so now no problem.

2012-12-06mmc: sdhci: add quirk for lack of 1.8v supportDaniel Drake
The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available. Add a quirk so that systems such as this one can override disable 1.8v support, adding support for UHS-I cards (by running them at 3.3v). This avoids a problem where the system would first try to run the card at 1.8v, fail, and then not be able to fully reset the card to retry at the normal 3.3v voltage. This is more appropriate than using the MISSING_CAPS quirk, which is intended for cases where the SDHCI controller is actually lying about its capabilities, and would force us to somehow override both caps words from another source.

Merge 'block-dev' branch. I was going to just mark everything here for stable and leave it to the 3.8 merge window, but having decided on doing another -rc, I migth as well merge it now. This removes the bd_block_size_semaphore semaphore that was added in this release to fix a race condition between block size changes and block IO, and replaces it with atomicity guaratees in fs/buffer.c instead, along with simplifying fs/block-dev.c. This removes more lines than it adds, makes the code generally simpler, and avoids the latency/rt issues that the block size semaphore introduced for mount. I'm not happy with the timing, but it wouldn't be much better doing this during the merge window and then having some delayed back-port of it into stable. * block-dev: blkdev_max_block: make private to fs/buffer.c direct-io: don't read inode->i_blkbits multiple times blockdev: remove bd_block_size_semaphore again fs/buffer.c: make block-size be per-page and protected by the page lock
