2008-10-16cpuidle: use last_state which can reflect the actual state enteredVenkatesh Pallipadi
cpuidle accounts the idle time for the C-state it was trying to enter and not to the actual state that the driver eventually entered. The driver may select a different state than the one chosen by cpuidle due to constraints like bus-mastering, etc. Change the time acounting code to look at the dev->last_state after returning from target_state->enter(). Driver can modify dev->last_state internally, inside the enter routine to reflect the actual C-state entered.

2008-10-09Don't allow splice() to files opened with O_APPENDLinus Torvalds
This is debatable, but while we're debating it, let's disallow the combination of splice and an O_APPEND destination. It's not entirely clear what the semantics of O_APPEND should be, and POSIX apparently expects pwrite() to ignore O_APPEND, for example. So we could make up any semantics we want, including the old ones. But Miklos convinced me that we should at least give it some thought, and that accepting writes at arbitrary offsets is wrong at least for IS_APPEND() files (which always have O_APPEND set, even if the reverse isn't true: you can obviously have O_APPEND set on a regular file). So disallow O_APPEND entirely for now. I doubt anybody cares, and this way we have one less gray area to worry about.

This fixes the previous fix, which was completely wrong on closer inspection. This version has been manually tested with a user-space test harness and generates sane values.

2008-10-07net: Fix netdev_run_todo dead-lockHerbert Xu
Benjamin Thery tracked down a bug that explains many instances of the error unregister_netdevice: waiting for %s to become free. Usage count = %d It turns out that netdev_run_todo can dead-lock with itself if a second instance of it is run in a thread that will then free a reference to the device waited on by the first instance. The problem is really quite silly. We were trying to create parallelism where none was required. As netdev_run_todo always follows a RTNL section, and that todo tasks can only be added with the RTNL held, by definition you should only need to wait for the very ones that you've added and be done with it. There is no need for a second mutex or spinlock. This is exactly what the following patch does. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2008-10-07tcp: Fix possible double-ack w/ user dmaAli Saidi
From: Ali Saidi <saidi@engin.umich.edu> When TCP receive copy offload is enabled it's possible that tcp_rcv_established() will cause two acks to be sent for a single packet. In the case that a tcp_dma_early_copy() is successful, copied_early is set to true which causes tcp_cleanup_rbuf() to be called early which can send an ack. Further along in tcp_rcv_established(), __tcp_ack_snd_check() is called and will schedule a delayed ACK. If no packets are processed before the delayed ack timer expires the packet will be acked twice. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-07net: only invoke dev->change_rx_flags when device is UPPatrick McHardy
Jesper Dangaard Brouer <hawk@comx.dk> reported a bug when setting a VLAN device down that is in promiscous mode: When the VLAN device is set down, the promiscous count on the real device is decremented by one by vlan_dev_stop(). When removing the promiscous flag from the VLAN device afterwards, the promiscous count on the real device is decremented a second time by the vlan_change_rx_flags() callback. The root cause for this is that the ->change_rx_flags() callback is invoked while the device is down. The synchronization is meant to mirror the behaviour of the ->set_rx_mode callbacks, meaning the ->open function is responsible for doing a full sync on open, the ->close() function is responsible for doing full cleanup on ->stop() and ->change_rx_flags() is meant to do incremental changes while the device is UP. Only invoke ->change_rx_flags() while the device is UP to provide the intended behaviour.

2008-10-06atmel-mci: Initialize BLKR before sending data transfer commandHaavard Skinnemoen
The atmel-mci driver sometimes fails data transfers like this: mmcblk0: error -5 transferring data end_request: I/O error, dev mmcblk0, sector 2749769 end_request: I/O error, dev mmcblk0, sector 2749777 It turns out that this might be caused by the BLKR register (which contains the block size and the number of blocks being transfered) being initialized too late. This patch moves the initialization of BLKR so that it contains the correct value before the block transfer command is sent. This error is difficult to reproduce, but if you insert a long delay (mdelay(10) or thereabouts) between the calls to atmci_start_command() and atmci_submit_data(), all transfers seem to fail without this patch, while I haven't seen any failures with this patch.

2008-10-06x86 ACPI: Blacklist two HP machines with buggy BIOSesRafael J. Wysocki
There is a bug in the BIOSes of some HP boxes with AMD Turions which connects IO-APIC pins with ACPI thermal trip points in such a way that if the state of the IO-APIC is not as expected by the (buggy) BIOS, the thermal trip points are set to insanely low values (usually all of them become 16 degrees Celsius). As a result, thermal throttling kicks in and knock the system down to its shoes. Unfortunately some of the recent IO-APIC changes made the bug show up. To prevent this from happening, blacklist machines that are known to be affected (nx6115 and 6715b in this particular case). This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as a regression from 2.6.26. On my box it was caused by: commit 691874fa96d6349a8b60f8ea9c2bae52ece79941 Author: Maciej W.
