2012-04-04ARM: OMAP: clock: fix race in disable all clocksNishanth Menon
clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y. Since clk_disable_unused is called as lateinitcall, there can be more than a few workqueues executing off secondary CPU(s). The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused. We ensure instead that the entire list traversal is protected by the lock allowing for parent child clock traversal which could be potentially be done by runtime operations to be safe as well.

2012-04-04Revert "nouveau/bios: Fix tracking of BIOS image data"Linus Torvalds
This reverts commit d06221c0617ab6d0bc41c4980cefdd9c8cc9a1c1. It turns out to trigger the "BUG_ON(!PageCompound(page))" in kfree(), apparently because the code ends up trying to free somethng that was never kmalloced in the first place. BenH points out that the patch was untested and wasn't meant to go into the upstream kernel that quickly in the first place.

2012-04-05sh: fix clock-sh7757 for the latest sh_mobile_sdhi driverShimoda, Yoshihiro
The commit 996bc8aebd2cd5b6d4c5d85085f171fa2447f364 (mmc: sh_mobile_sdhi: do not manage PM clocks manually) modified the sh_mobile_sdhi driver to remove the clk_enable/clk_disable. So, we need to change the "CLKDEV_CON_ID" to "CLKDEV_DEV_ID".

2012-04-04ARM: OMAP3xxx: HSMMC: avoid erratum workaround when transceiver is attachedGrazvydas Ignotas
If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems 2.1.1.128 erratum doesn't apply and there is no data corruption, probably because of different signal timing. The workaround for this erratum disables multiblock reads, which causes dramatic loss of performance (over 75% slower), so avoid it when transceiver is present.

2012-04-03ixgbe: driver fix for link flapMultanen, Eric W
Fix up code so that changes in DCB settings are detected only when ixgbe_dcbnl_set_all is called. Previously, a series of 'change' commands followed by a call to ixgbe_dcbnl_set_all() would always be handled as a HW change - even if the net change was zero. This patch checks for this case of no actual change and skips going through the HW set process. Without this fix, the link could reset and result in a link flap. The core change in this patch is to check for changes in the ixgbe_copy_dcb_cfg() routine - and return a bitmask of detected changes. The other places where changes were detected previously can be removed.

First modify the asm load helper functions to handle: - know positive offsets - know negative offsets - any offset then the compiler can be modified to explicitly use these helper when appropriate.

2012-04-03tcp: allow splice() to build full TSO packetsEric Dumazet
vmsplice()/splice(pipe, socket) call do_tcp_sendpages() one page at a time, adding at most 4096 bytes to an skb. (assuming PAGE_SIZE=4096) The call to tcp_push() at the end of do_tcp_sendpages() forces an immediate xmit when pipe is not already filled, and tso_fragment() try to split these skb to MSS multiples. 4096 bytes are usually split in a skb with 2 MSS, and a remaining sub-mss skb (assuming MTU=1500) This makes slow start suboptimal because many small frames are sent to qdisc/driver layers instead of big ones (constrained by cwnd and packets in flight of course) In fact, applications using sendmsg() (adding an additional memory copy) instead of vmsplice()/splice()/sendfile() are a bit faster because of this anomaly, especially if serving small files in environments with large initial [c]wnd. Call tcp_push() only if MSG_MORE is not set in the flags parameter. This bit is automatically provided by splice() internals but for the last page, or on all pages if user specified SPLICE_F_MORE splice() flag. In some workloads, this can reduce number of sent logical packets by an order of magnitude, making zero-copy TCP actually faster than one-copy :) Reported-by: Tom Herbert <therbert@google.com> Cc: Nandita Dukkipati <nanditad@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Tom Herbert <therbert@google.com> Cc: Yuchung Cheng <ycheng@google.com> Cc: H.K.

2012-04-03ppp: Don't stop and restart queue on every TX packetDavid Woodhouse
For every transmitted packet, ppp_start_xmit() will stop the netdev queue and then, if appropriate, restart it. This causes the TX softirq to run, entirely gratuitously. This is "only" a waste of CPU time in the normal case, but it's actively harmful when the PPP device is a TEQL slave — the wakeup will cause the offending device to receive the next TX packet from the TEQL queue, when it *should* have gone to the next slave in the list. We end up seeing large bursts of packets on just *one* slave device, rather than using the full available bandwidth over all slaves. This patch fixes the problem by *not* unconditionally stopping the queue in ppp_start_xmit(). It adds a return value from ppp_xmit_process() which indicates whether the queue should be stopped or not. It *doesn't* remove the call to netif_wake_queue() from ppp_xmit_process(), because other code paths (especially from ppp_output_wakeup()) need it there and it's messy to push it out to the other callers to do it based on the return value. So we leave it in place — it's a no-op in the case where the queue wasn't stopped, so it's harmless in the TX path. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: David S.

2012-04-03net: fix /proc/net/dev regressionEric Dumazet
Commit f04565ddf52 (dev: use name hash for dev_seq_ops) added a second regression, as some devices are missing from /proc/net/dev if many devices are defined. When seq_file buffer is filled, the last ->next/show() method is canceled (pos value is reverted to value prior ->next() call) Problem is after above commit, we dont restart the lookup at right position in ->start() method. Fix this by removing the internal 'pos' pointer added in commit, since we need to use the 'loff_t *pos' provided by seq_file layer. This also reverts commit 5cac98dd0 (net: Fix corruption in /proc/*/net/dev_mcast), since its not needed anymore.

2012-04-03Input: sentelic - filter taps in absolute modeOskari Saarenmaa
Taps in absolute positioning single-finger mode are currently reported as physical clicks by the driver. This should be handled by userspace, not the kernel. When a tap occurs, the FSP_PB0_LBTN bit is set, but the FSP_PB0_PHY_BTN is not. We use this to filter out physical clicks from taps.

2012-04-03lsm_audit: don't specify the audit pre/post callbacks in 'struct ↵Linus Torvalds
common_audit_data' It just bloats the audit data structure for no good reason, since the only time those fields are filled are just before calling the common_lsm_audit() function, which is also the only user of those fields. So just make them be the arguments to common_lsm_audit(), rather than bloating that structure that is passed around everywhere, and is initialized in hot paths.
