* [WATCHDOG] Pre-Timeout flagsCorey Minyard2006-06-20
| | | | | | | | | | | | | Some watchdog timers support the concept of a "pretimeout" which occurs some time before the real timeout. The pretimeout can be delivered via an interrupt or NMI and can be used to panic the system when it occurs (so you get useful information instead of a blind reboot).

* [PATCH] powerpc: Fix 64k pages on non-partitioned machinesArnd Bergmann2006-06-17
| | | | | | | | | | | | | The page size encoding passed to tlbie is incorrect for new-style large pages. This fixes it. This doesn't affect anything on older machines because mmu_psize_defs[psize].penc (the page size encoding) is 0 for 4k and 16M pages (the two are distinguished by a separate "is a large page" bit).

* [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.

Under the ARM IRQ code, this would not have been a visible problem because the "simple" IRQ handling had no re-entrancy protection.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of all the SUN_570X logic and instead: 1) Make sure MEMARB_ENABLE is set when we probe the SRAM for config information. If that is off we will get timeouts. 2) Always try to sync with the firmware, if there is no firmware running do not treat it as an error and instead just report it the first time we notice this condition. 3) If there is no valid SRAM signature, assume the device is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT. Update driver version and release date. With help from Michael Chan and Fabio Massimo Di Nitto. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | [PATCH] powerpc: console_initcall ordering issuesMilton Miller2006-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Milton Miller <miltonm@bga.com> The add_preferred_console call in rtas_console.c was not causing the console to be selected. It turns out that the add_preferred_console was being called after the hvc_console driver was registered. It only works when it is called before the console driver is registered. Reorder hvc_console.o after the hvc_console drivers to allow the selection during console_initcall processing.
