2010-01-06x86, irq: Check move_in_progress before freeing the vector mappingSuresh Siddha
With the recent irq migration fixes (post 2.6.32), Gary Hade has noticed "No IRQ handler for vector" messages during the 2.6.33-rc1 kernel boot on IBM AMD platforms and root caused the issue to this commit: > commit 23359a88e7eca3c4f402562b102f23014db3c2aa > Author: Suresh Siddha <suresh.b.siddha@intel.com> > Date: Mon Oct 26 14:24:33 2009 -0800 > > x86: Remove move_cleanup_count from irq_cfg As part of this patch, we have removed the move_cleanup_count check in smp_irq_move_cleanup_interrupt(). With this change, we can run into a situation where an irq cleanup interrupt on a cpu can cleanup the vector mappings associated with multiple irqs, of which one of the irq's migration might be still in progress. As such when that irq hits the old cpu, we get the "No IRQ handler" messages. Fix this by checking for the irq_cfg's move_in_progress and if the move is still in progress delay the vector cleanup to another irq cleanup interrupt request (which will happen when the irq starts arriving at the new cpu destination).

2010-01-06drm/i915: Add DP dpll limit on ironlake and use existing DPLL search functionZhao Yakui
For some clocks, the old Ironlake DPLL calculator wold give m/n/p combinations that didn't match the spreadsheet of what HW validation tests. Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

There is nothing special to be done for interrupts which can wakeup the device from sleep on CP-INTC, but not having a set_wake implemented prevents use of common drivers which expect this function to be implemented for all wakeup interrupt sources. This patch fixes the issue encountered when using the omap-rtc driver on DA850. On DA850 the RTC alarm interrupt is used to wake up the SoC from deep sleep mode. Without this patch, the disable_irq_wake throws an unbalanced wake disable warning while resuming because the previous enable call fails for lack of set_wake implementation.

2010-01-06Input: evdev - be less aggressive about sending SIGIO notifiesAdam Jackson
When using realtime signals, we'll enqueue one signal for every event. This is unfortunate, because (for example) keyboard presses are three events: key, msc scancode, and syn. They'll be enqueued fast enough in kernel space that all three events will be ready to read by the time userspace runs, so the first invocation of the signal handler will read all three events, but then the second two invocations still have to run to do no work. Instead, only send the SIGIO notification on syn events. This is a slight abuse of SIGIO semantics, in principle it ought to fire as soon as any events are readable. But it matches evdev semantics, which is more important since SIGIO is rather vaguely defined to begin with.

2010-01-06Input: serio - fix potential deadlock when unbinding driversEric W. Biederman
sysfs_remove_group() waits for sysfs attributes to be removed, therefore we do not need to worry about driver-specific attributes being accessed after driver has been detached from the device. In fact, attempts to take serio->drv_mutex in attribute methods may lead to the following deadlock: sysfs_read_file() fill_read_buffer() sysfs_get_active_two() psmouse_attr_show_helper() serio_pin_driver() serio_disconnect_driver() mutex_lock(&serio->drv_mutex); <--------> mutex_lock(&serio_drv_mutex); psmouse_disconnect() sysfs_remove_group(... psmouse_attr_group); .... sysfs_deactivate(); wait_for_completion(); Fix this by removing calls to serio_[un]pin_driver() and functions themselves and using driver-private mutexes to serialize access to attribute's set() methods that may change device state.

2010-01-05mac80211: fix skb buffering issueJohannes Berg
Since I removed the master netdev, we've been keeping internal queues only, and even before that we never told the networking stack above the virtual interfaces about congestion. This means that packets are queued in mac80211 and the upper layers never know, possibly leading to memory exhaustion and other problems. This patch makes all interfaces multiqueue and uses ndo_select_queue to put the packets into queues per AC. Additionally, when the driver stops a queue, we now stop all corresponding queues for the virtual interfaces as well. The injection case will use VO by default for non-data frames, and BE for data frames, but downgrade any data frames according to ACM. It needs to be fleshed out in the future to allow chosing the queue/AC in radiotap.

2010-01-05rt2x00: Fix LED configuration setting for rt2800.Gertjan van Wingerde
rt2800_blink_set uses an illegal value to set the LED_CFG_G_LED_MODE field of the LED_CFG register. This field is only 2 bits large, so should be initialized with value that fits. Use default value from the vendor driver. Signed-off-by: Gertjan van Wingerde <gwingerde@gmail.com> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2010-01-05exofs: simple_write_end does not mark_inode_dirtyBoaz Harrosh
exofs uses simple_write_end() for it's .write_end handler. But it is not enough because simple_write_end() does not call mark_inode_dirty() when it extends i_size. So even if we do call mark_inode_dirty at beginning of write out, with a very long IO and a saturated system we might get the .write_inode() called while still extend-writing to file and miss out on the last i_size updates. So override .write_end, call simple_write_end(), and afterwords if i_size was changed call mark_inode_dirty(). It stands to logic that since simple_write_end() was the one extending i_size it should also call mark_inode_dirty(). But it looks like all users of simple_write_end() are memory-bound pseudo filesystems, who could careless about mark_inode_dirty(). I might submit a warning-comment patch to simple_write_end() in future. CC: Stable <stable@kernel.org> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
