2007-05-31[ALSA] hda-intel: fix ASUS M2V detectionDaniel Drake
Commit f32610edab47f36946d23b883aeae91e15986121 added ALC660VD support, but this caused a 2.6.21 regression for some users. The ASUS M2V device is now detected as ALC660VD rather than ALC660/861 but the PCI quirk was not carried over. This patch allows affected users to use audio again. http://bugzilla.kernel.org/show_bug.cgi?id=8273 https://bugs.gentoo.org/show_bug.cgi?id=178243 Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2007-05-30NFS: Fix a refcount leakage in O_DIRECTTrond Myklebust
The current code is leaking a reference to dreq->kref when the calls to nfs_direct_read_schedule() and nfs_direct_write_schedule() return an error. This patch moves the call to kref_put() from nfs_direct_wait() back into nfs_direct_read() and nfs_direct_write() (which are the functions that actually took the reference in the first place) fixing the leak.

2007-05-30e1000: restore netif_poll_enable call but make sure IRQs are offHerbert Xu
This restores the previously removed netif_poll_enable call in e1000_open. It's needed on all but the first call to e1000_open for a NIC as e1000_close always calls netif_poll_disable. netif_poll_enable can only be called safely if no polls have been scheduled. This should be the case as long as we don't enter our IRQ handler. In order to guarantee this we explicitly disable IRQs as early as possible when we're probing the NIC.

2007-05-29NOHZ: prevent multiplication overflow - stop timer for huge timeoutsThomas Gleixner
get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case there is no timer pending. On 64 bit machines this results in a multiplication overflow in tick_nohz_stop_sched_tick(). Reported by: Dave Miller <davem@davemloft.net> Make the return value a constant and limit the return value to a 32 bit value. When the max timeout value is returned, we can safely stop the tick timer device. The max jiffies delta results in a 12 days timeout for HZ=1000. In the long term the get_next_timer_interrupt() code needs to be reworked to return ktime instead of jiffies, but we have to wait until the last users of the original NO_IDLE_HZ code are converted.

2007-05-29IB/cm: Fix stale connection detectionSean Hefty
The ib_cm can incorrectly detect a stale connection (a new connection request for a QPN that is already connected) as a duplicate connection request. Separate the handling of potential duplicate REQs from stale connections. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-05-29IPoIB/cm: Fix performance regression on MellanoxMichael S. Tsirkin
commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe performance regression on Mellanox cards, because keeping a QP in the error state for extended periods of time moves hardware to the slow path (until the QP is destroyed). For example, MPI latency goes from ~3 usecs to ~7 usecs. Fix this by posting a send WR on one of the QPs that are being flushed, instead of using a separate drain QP that is kept in the error state. This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>, reported and bisected by Scott Weitzenkamp at Cisco and debugged by Sasha Mikheev at Voltaire. Signed-off-by: Michael S.

2007-05-29IB/mthca: Fix handling of send CQE with error for QPs connected to SRQMichael S. Tsirkin
mthca_free_err_wqe() currently treats both send and receive CQEs identically if a QP is using an SRQ. But for Tavor hardware, send CQEs with error can be chained together even if the RQ is part of SRQ, so we may miss some CQEs. Fix by following the WQE chain for all send CQEs even for non-SRQ QPs. This fixes crashes in IPoIB CM: <https://bugs.openfabrics.org//show_bug.cgi?id=604> Signed-off-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
