* x86, dumpstack: Fix unused variable warningRakib Mullick2011-01-071-6/+0
| | | | | | | | | | | | | | | In dump_stack function, bp isn't used anymore, which is introduced by commit 9c0729dc8062bed96189bd14ac6d4920f3958743. This patch removes bp completely.

* x86, NMI: Clean-up default_do_nmi()Don Zickus2011-01-071-16/+14
| | | | | | | | | | | | | | Just re-arrange the code a bit to make it easier to follow what is going on. Basically un-negating the if-statement and swapping the code inside the if-statement with code outside. No functional changes.

* x86, NMI: Allow NMI reason io port (0x61) to be processed on any CPUDon Zickus2011-01-071-6/+10
| | | | | | | | | | | | | In original NMI handler, NMI reason io port (0x61) is only processed on BSP. This makes it impossible to hot-remove BSP. To solve the issue, a raw spinlock is used to allow the port to be processed on any CPU.

* x86, NMI: Remove DIE_NMI_IPIDon Zickus2011-01-078-21/+12
| | | | | | | | | | | | | | | | | With priorities in place and no one really understanding the difference between DIE_NMI and DIE_NMI_IPI, just remove DIE_NMI_IPI and convert everyone to DIE_NMI. This also simplifies default_do_nmi() a little bit. Instead of calling the die_notifier in both the if and else part, just pull it out and call it before the if-statement. This has the side benefit of avoiding a call to the ioport to see if there is an external NMI sitting around until after the (more frequent) internal NMIs are dealt with.

* x86, NMI: Add priorities to handlersDon Zickus2011-01-078-6/+29
| | | | | | | | | | | | | | | | | In order to consolidate the NMI die_chain events, we need to setup the priorities for the die notifiers. I started by defining a bunch of common priorities that can be used by the notifier blocks. Then I modified the notifier blocks to use the newly created priorities. Now that the priorities are straightened out, it should be easier to remove the event DIE_NMI_IPI.

* x86: Convert some devices to use DIE_NMIUNKNOWNDon Zickus2011-01-073-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | They are a handful of places in the code that register a die_notifier as a catch all in case no claims the NMI. Unfortunately, they trigger on events like DIE_NMI and DIE_NMI_IPI, which depending on when they registered may collide with other handlers that have the ability to determine if the NMI is theirs or not. The function unknown_nmi_error() makes one last effort to walk the die_chain when no one else has claimed the NMI before spitting out messages that the NMI is unknown. This is a better spot for these devices to execute any code without colliding with the other handlers. The two drivers modified are only compiled on x86 arches I believe, so they shouldn't be affected by other arches that may not have DIE_NMIUNKNOWN defined.

* x86, NMI: Add NMI symbol constants and rename memory parity to PCI SERRHuang Ying2011-01-072-26/+37
| | | | | | | | | | | | | | | | | | Replace the NMI related magic numbers with symbol constants. Memory parity error is only valid for IBM PC-AT, newer machine use bit 7 (0x80) of 0x61 port for PCI SERR. While memory error is usually reported via MCE. So corresponding function name and kernel log string is changed. But on some machines, PCI SERR line is still used to report memory errors. This is used by EDAC, so corresponding EDAC call is reserved.

* perf tools: Fix buffer overflow error when specifying all tracepointsHan Pingtian2011-01-061-31/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | I found when specifying all tracepoints with -e to one of subcommand, such as 'stat', the program will trigger a buffer overflow error, like this: *** buffer overflow detected ***: ./perf terminated ======= Backtrace: ========= /lib64/libc.so.6(__fortify_fail+0x37)[0x382cefb2c7] .... The tracepoints are separated by comma, something like this: $ perf stat -a -e `perf list |grep Tracepoint|awk -F'[' '{gsub(/[[:space:]]+/,"",$1);array[FNR]=$1}END{outputs=array[1];for (i=2;i<=FNR;i++){ outputs=outputs "," array[i];};print outputs}'` The root reason of this problem is that store_event_type() is called for all events, and will overflow the 'filename' at: strncat(filename, orgname, strlen(orgname)); This patch fixes it by calling store_event_type() only when the event name has been found.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the usage of the perf_event.h header file between command modules and the supporting code in util. It is necessary to ensure that ALL files use the SAME perf_event.h header from the kernel source tree. There were a couple of #include <linux/perf_event.h> mixed with #include "../../perf_event.h". This caused issues on some distros because of mismatch in the layout of struct perf_event_attr. That eventually led perf stat to segfault. Cc: David S.

* x86: Avoid calling arch_trigger_all_cpu_backtrace() at the same timeDongdong Deng2011-01-051-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spin_lock_debug/rcu_cpu_stall detector uses trigger_all_cpu_backtrace() to dump cpu backtrace. Therefore it is possible that trigger_all_cpu_backtrace() could be called at the same time on different CPUs, which triggers and 'unknown reason NMI' warning. The following case illustrates the problem: CPU1 CPU2 ... CPU N trigger_all_cpu_backtrace() set "backtrace_mask" to cpu mask | generate NMI interrupts generate NMI interrupts ... \ | / \ | / The "backtrace_mask" will be cleaned by the first NMI interrupt at nmi_watchdog_tick(), then the following NMI interrupts generated by other cpus's arch_trigger_all_cpu_backtrace() will be taken as unknown reason NMI interrupts. This patch uses a test_and_set to avoid the problem, and stop the arch_trigger_all_cpu_backtrace() from calling to avoid dumping a double cpu backtrace info when there is already a trigger_all_cpu_backtrace() in progress.

| | * atl1: fix oops when changing tx/rx ring paramsJ. K. Cliburn2011-01-031-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3f5a2a713aad28480d86b0add00c68484b54febc zeroes out the statistics message block (SMB) and coalescing message block (CMB) when adapter ring resources are freed. This is desirable behavior, but, as a side effect, the commit leads to an oops when atl1_set_ringparam() attempts to alter the number of rx or tx elements in the ring buffer (by using ethtool -G, for example). We don't want SMB or CMB to change during this operation. Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring parameters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed that the preprocessor condition used to find the size of dma_addr_t yielded the wrong result for some architectures and configurations. This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet another case to the condition. However, 64-bit MIPS configurations are not detected reliably either. This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that isn't yet defined everywhere it should be. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S.

This is most likely a bug in that version of IOS, since it is fixed in later versions. As a workaround this patch allows a module parameter to be set to disable compressing the protocol ID. See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979 RFC 1990 allows an implementation to formulate MP fragments as if protocol compression had been negotiated. This allows us to always send compressed protocol IDs. But some implementations don't accept MP fragments with compressed protocol IDs. This parameter allows us to interoperate with them. The default value of the configurable parameter is the same as the current behavior: protocol compression is enabled. If protocol compression is disabled we will not send compressed protocol IDs. This is based on an earlier patch by Bob Gilligan (using a sysctl). Module parameter is writable to allow for enabling even if ppp is already loaded for other uses.

This often causes the sysfs 'carrier' attribute to be '1' even though no signal has actually been found. uea_probe usbatm_usb_probe driver->bind (uea_bind) uea_boot kthread_run(uea_kthread) uea_kthread usbatm_atm_init uea_start_reset atm_dev_register UPDATE_ATM_SIGNAL UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if not, will not update the PHY signal state. Because of the race that does not always happen in time, and the PHY signal state remains ATM_PHY_SIG_FOUND even though no signal exists. To fix the race, just create the kthread during initialization, and only after initialization is complete, start the thread that reboots the device and initializes PHY state.

The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the irqsoff tracer is in use, stop tracing the interrupt disable interval when returning to userspace. Tracing userspace execution time as interrupts disabled time is not helpful for kernel performance analysis purposes. Only do so if the irqsoff tracer is enabled, to avoid overhead for lockdep, which doesn't care.
