* [PATCH] acpiphp: turn off slot power at error caseMUNEDA Takahiro2006-06-19
| | | | | | | | | | | | When acpiphp_enable_slot() is failed, acpiphp does not change the slot->flags. Therefore, when user tries to read power status, acpiphp_get_power_status() returns the enable status whether the slot is not really enabled. This patch fixes this BUG.

* [PATCH] acpiphp: hotplug slot hotplugMUNEDA Takahiro2006-06-19
| | | | | | | | | | | | | | | | | | | | | | o hotplug slots add When the hot-added PCI device is p2p bridge, acpiphp calls find_p2p_bridge() to add hotplug slots. o hotplug slots remove When the hot-removing PCI device is p2p bridge, acpiphp calls cleanup_p2p_bridge() to remove hotplug slots. o notify handler exchange When the p2p bridge is added, acpiphp changes the notify hanlder. If no bridge device is inserted into the hotpluggable PCI slot, acpiphp installs the notify handler for function. After the p2p bridge hot-add, acpiphp has to install the notify handler for bridge. Because, the role of the handlers are not same. The hot-remove case is ditto. Signed-off-by: MUNEDA Takahiro <muneda.takahiro@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] arm_timer: remove a racy and obsolete PF_EXITING checkOleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state) in run_posix_cpu_timers(). However, for some reason it does so only for CPUCLOCK_PERTHREAD case (which is imho wrong). Also, this check is not reliable, PF_EXITING could be set on another cpu without any locks/barriers just after the check, so it can't prevent from attaching the timer to the exiting task. The previous patch makes this check unneeded. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] run_posix_cpu_timers: remove a bogus BUG_ON()Oleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | do_exit() clears ->it_##clock##_expires, but nothing prevents another cpu to attach the timer to exiting process after that. arm_timer() tries to protect against this race, but the check is racy. After exit_notify() does 'write_unlock_irq(&tasklist_lock)' and before do_exit() calls 'schedule() local timer interrupt can find tsk->exit_state != 0. If that state was EXIT_DEAD (or another cpu does sys_wait4) interrupted task has ->signal == NULL. At this moment exiting task has no pending cpu timers, they were cleanuped in __exit_signal()->posix_cpu_timers_exit{,_group}(), so we can just return from irq.

* [PATCH] check_process_timers: fix possible lockupOleg Nesterov2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | If the local timer interrupt happens just after do_exit() sets PF_EXITING (and before it clears ->it_xxx_expires) run_posix_cpu_timers() will call check_process_timers() with tasklist_lock + ->siglock held and check_process_timers: t = tsk; do { .... do { t = next_thread(t); } while (unlikely(t->flags & PF_EXITING)); } while (t != tsk); the outer loop will never stop. Actually, the window is bigger. Another process can attach the timer after ->it_xxx_expires was cleared (see the next commit) and the 'if (PF_EXITING)' check in arm_timer() is racy (see the one after that).

* [PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger2006-06-17
| | | | | | | | | | | | | A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

* [PATCH] fix cdrom openJens Axboe2006-06-17
| | | | | | | | | | | | | | | | Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

* [PATCH] tmpfs: time granularity fix for [acm]time going backwardsRobin H. Johnson2006-06-12
| | | | | | | | | | | | | | | | | | | | | | | | I noticed a strange behavior in a tmpfs file system the other day, while building packages - occasionally, and seemingly at random, make decided to rebuild a target. However, only on tmpfs. A file would be created, and if checked, it had a sub-second timestamp. However, after an utimes related call where sub-seconds should be set, they were zeroed instead. In the case that a file was created, and utimes(...,NULL) was used on it in the same second, the timestamp on the file moved backwards. After some digging, I found that this was being caused by tmpfs not having a time granularity set, thus inheriting the default 1 second granularity. Hugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11. Unfortunately, the granularity of CURRENT_TIME, often used in filesystems, does not match the default granularity set by alloc_super. A few more such discrepancies have been found, but this is the most important to fix now. Signed-off-by: Robin H.

The documentation states that a 1 should be written to the relevant bit to acknowledge a GPIO interrupt, but that is not what the code does. The problem is that the |= writes back 1s for all the *other* interrupts represented in the register, so interrupts could get lost. For example, if interrupts are pending for GPIO B10 and B12, ISR_B would have the value 0x00001400. Then when the interrupt code handles GPIO B10, it eventually calls imx_gpio_ack_irq(IRQ_GPIOB(10)), which effectively does this: ISR_B |= 1 << 10; with the result that (0x00001400 | 0x00000400) is written, clearing the interrupt status bits for *both* GPIO B10 and B12. The fix is to write 1s only for the interrupts we want to clear. The same problem seems to be occurring in the DMA code; this patch does not address those issues.

I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently don't handle errors properly when resuming a PCI device: * In pci_default_resume() we capture the error code returned by pci_enable_device() but don't pass it up to the caller. Introduced by commit 95a629657dbe28e44a312c47815b3dc3f1ce0970 * In pci_resume_device(), the errors possibly returned by the driver's .resume method or by the generic pci_default_resume() function are ignored. This patch fixes both issues. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* | [SPARC]: Migration cost tune up in sparc smp.Krzysztof Helt2006-06-11
| | | | | | | | | | | | | | | | | | This patch sets the max_cache_size value required to tune up scheduler in SMP systems. Otherwise, the calculated migration_cost is too high and task scheduling may lock up. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing PCI config space accesses to non-present PCI slots can result in fatal JBUS errors if the PCI config access hypervisor call is performed on cpus other than the boot cpu. PCI config space accesses to present PCI slots works just fine. Recursively traverse the OBP device tree under the PCI controller node and record all present device IDs into a small hash table. Avoid the hypervisor call for any PCI config space access attempt for a device not recorded in the hash table. Signed-off-by: David S. Miller <davem@davemloft.net>
