2011-03-09ASoC: AM3517: Update codec name after multi-component updateAbhilash K V
The i2c client device name (".2-001a" in this case, including the separator period) for the AIC23 codec on the TI AM3517-EVM was appended to the codec_name member of am3517evm_dai to resolve the names mismatch happening in soc_bind_dai_link(), due to which the card was not getting registered.

2011-03-08r6040: fix multicast operationsShawn Lin
The original code does not work well when the number of mulitcast address to handle is greater than MCAST_MAX. It only enable promiscous mode instead of multicast hash table mode, so the hash table function will not be activated and all multicast frames will be recieved in this condition. This patch fixes the following issues with the r6040 NIC operating in multicast: 1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC hash table registers to make it process multicast traffic. 2) When the number of multicast address to handle is smaller than MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}. 3) The hashing of the address was not correct, due to an invalid substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an incorrect crc algorithm (ether_crc_le) instead of (ether_crc). 4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast hash table function.

2011-03-08mmc: fix CONFIG_MMC_UNSAFE_RESUME regressionOhad Ben-Cohen
30201e7f3 ("mmc: skip detection of nonremovable cards on rescan") allowed skipping detection of nonremovable cards on mmc_rescan(). The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

2011-03-08unfuck proc_sysctl ->d_compare()Al Viro
a) struct inode is not going to be freed under ->d_compare(); however, the thing PROC_I(inode)->sysctl points to just might. Fortunately, it's enough to make freeing that sucker delayed, provided that we don't step on its ->unregistering, clear the pointer to it in PROC_I(inode) before dropping the reference and check if it's NULL in ->d_compare(). b) I'm not sure that we *can* walk into NULL inode here (we recheck dentry->seq between verifying that it's still hashed / fetching dentry->d_inode and passing it to ->d_compare() and there's no negative hashed dentries in /proc/sys/*), but if we can walk into that, we really should not have ->d_compare() return 0 on it! Said that, I really suspect that this check can be simply killed. Nick? Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-07bonding 802.3ad: Fix the state machine locking v2Nils Carlson
Changes since v1: * Clarify an unclear comment * Move a (possible) name change to a separate patch The ad_rx_machine, ad_periodic_machine and ad_port_selection_logic functions all inspect and alter common fields within the port structure. Previous to this patch, only the ad_rx_machines were mutexed, and the periodic and port_selection could run unmutexed against an ad_rx_machine trigged by an arriving LACPDU. This patch remedies the situation by protecting all the state machines from concurrency. This is accomplished by locking around all the state machines for a given port, which are executed at regular intervals; and the ad_rx_machine when handling an incoming LACPDU.

2011-03-07net: fix multithreaded signal handling in unix recv routinesRainer Weikusat
The unix_dgram_recvmsg and unix_stream_recvmsg routines in net/af_unix.c utilize mutex_lock(&u->readlock) calls in order to serialize read operations of multiple threads on a single socket. This implies that, if all n threads of a process block in an AF_UNIX recv call trying to read data from the same socket, one of these threads will be sleeping in state TASK_INTERRUPTIBLE and all others in state TASK_UNINTERRUPTIBLE. Provided that a particular signal is supposed to be handled by a signal handler defined by the process and that none of this threads is blocking the signal, the complete_signal routine in kernel/signal.c will select the 'first' such thread it happens to encounter when deciding which thread to notify that a signal is supposed to be handled and if this is one of the TASK_UNINTERRUPTIBLE threads, the signal won't be handled until the one thread not blocking on the u->readlock mutex is woken up because some data to process has arrived (if this ever happens). The included patch fixes this by changing mutex_lock to mutex_lock_interruptible and handling possible error returns in the same way interruptions are handled by the actual receive-code.

When copy_from_user is only able to copy some of the bytes we requested, we may end up creating a partially up to date page.

2011-03-07Btrfs: fix regressions in copy_from_user handlingChris Mason
Commit 914ee295af418e936ec20a08c1663eaabe4cd07a fixed deadlocks in btrfs_file_write where we would catch page faults on pages we had locked. But, there were a few problems: 1) The x86-32 iov_iter_copy_from_user_atomic code always fails to copy data when the amount to copy is more than 4K and the offset to start copying from is not page aligned. The result was btrfs_file_write looping forever retrying the iov_iter_copy_from_user_atomic We deal with this by changing btrfs_file_write to drop down to single page copies when iov_iter_copy_from_user_atomic starts returning failure. 2) The btrfs_file_write code was leaking delalloc reservations when iov_iter_copy_from_user_atomic returned zero. The looping above would result in the entire filesystem running out of delalloc reservations and constantly trying to flush things to disk. 3) btrfs_file_write will lock down page cache pages, make sure any writeback is finished, do the copy_from_user and then release them. Before the loop runs we check the first and last pages in the write to see if they are only being partially modified. If the start or end of the write isn't aligned, we make sure the corresponding pages are up to date so that we don't introduce garbage into the file. With the copy_from_user changes, we're allowing the VM to reclaim the pages after a partial update from copy_from_user, but we're not making sure the page cache page is up to date when we loop around to resume the write. We deal with this by pushing the up to date checks down into the page prep code. This fits better with how the rest of file_write works.

2011-03-06virtio: console: Don't access vqs if device was unpluggedAmit Shah
If a virtio-console device gets unplugged while a port is open, a subsequent close() call on the port accesses vqs to free up buffers. This can lead to a crash. The buffers are already freed up as a result of the call to unplug_ports() from virtcons_remove(). The fix is to simply not access vq information if port->portdev is NULL.

2011-03-06drm/i915: Do not overflow the MMADDR write FIFOChris Wilson
Whilst the GT is powered down (rc6), writes to MMADDR are placed in a FIFO by the System Agent. This is a limited resource, only 64 entries, of which 20 are reserved for Display and PCH writes, and so we must take care not to queue up too many writes. To avoid this, there is counter which we can poll to ensure there are sufficient free entries in the fifo. "Issuing a write to a full FIFO is not supported; at worst it could result in corruption or a system hang."

This reverts commit c2e0eb167070a6e9dcb49c84c13c79a30d672431. As it turns out, userspace already depends upon being able to enable tiling on existing bo which it promises to be large enough for its purposes i.e. it will not access beyond the end of the last full-tile row.

2011-03-04mm: use correct numa policy node for transparent hugepagesAndi Kleen
Pass down the correct node for a transparent hugepage allocation. Most callers continue to use the current node, however the hugepaged daemon now uses the previous node of the first to be collapsed page instead. This ensures that khugepaged does not mess up local memory for an existing process which uses local policy. The choice of node is somewhat primitive currently: it just uses the node of the first page in the pmd range. An alternative would be to look at multiple pages and use the most popular node. I used the simplest variant for now which should work well enough for the case of all pages being on the same node.
