* [PATCH] fix kernel-api doc for kernel/resource.cRandy Dunlap2006-07-311-1/+1
| | | | | | | | | | insert_resource() was unexported, so kernel-doc needs to be told to search kernel/resource.c for internal functions instead of exported functions so that it won't report an error.

* [PATCH] fix cond_resched() fixJim Houston2006-07-311-5/+5
| | | | | | | | | | | | | | In cond_resched_lock() it calls __resched_legal() before dropping the spin lock. __resched_legal() will always finds the preempt_count non-zero and will prevent the call to __cond_resched(). The attached patch adds a parameter to __resched_legal() with the expected preempt_count value.

* [PATCH] fix bad macro param in timer.cSteven Rostedt2006-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have #define INDEX(N) (base->timer_jiffies >> (TVR_BITS + N * TVN_BITS)) & TVN_MASK and it's used via list = varray[i + 1]->vec + (INDEX(i + 1)); So, due to underparenthesisation, this INDEX(i+1) is now a ... (TVR_BITS + i + 1 * TVN_BITS)) ... So this bugfix changes behaviour. It worked before by sheer luck: "If i was anything but 0, it was broken. But this was only used by s390 and arm. Since it was for the next interrupt, could that next interrupt be a problem (going into the second cascade)? But it was probably seldom wrong. That is, this would fail if the next interrupt was in the second cascade, and was wrapped. Which may never of happened. Also if it did happen, it would have just missed the interrupt. If an interrupt was missed, and no one was there to miss it, was it really missed :-)" Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] cpu hotplug: replace __devinit* with __cpuinit* for cpu notificationsChandra Seetharaman2006-07-317-13/+13
| | | | | | | | | | | | | | | | Few of the callback functions and notifier blocks that are associated with cpu notifications incorrectly have __devinit and __devinitdata. They should be __cpuinit and __cpuinitdata instead. It makes no functional difference but wastes text area when CONFIG_HOTPLUG is enabled and CONFIG_HOTPLUG_CPU is not.

* [PATCH] panic_on_oops: remove ssleep()Horms2006-07-316-28/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of an effort to unify the panic_on_oops behaviour across all architectures that implement it. It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

| | | | | | | | | | | | | | | | | | A recent commit (7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1) moved the call to nfsd_setuser out of the 'find a dentry for a filehandle' branch of fh_verify so that it would always be called. This had the unfortunately side-effect of moving *after* the call to decode_fh, so the prober fsuid was not set when nfsd_acceptable was called, the 'permission' check did the wrong thing.

* [PATCH] delay accounting: temporarily enable by defaultShailabh Nagar2006-07-314-12/+14
| | | | | | | | | | | | | | | | Enable delay accounting by default so that feature gets coverage testing without requiring special measures. Earlier, it was off by default and had to be enabled via a boot time param. This patch reverses the default behaviour to improve coverage testing. It can be removed late in the kernel development cycle if its believed users shouldn't have to incur any cost if they don't want delay accounting. Or it can be retained forever if the utility of the stats is deemed common enough to warrant keeping the feature on.

* [PATCH] genirq: {en,dis}able_irq_wake() need refcounting tooDavid Brownell2006-07-312-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | IRQs need refcounting and a state flag to track whether the the IRQ should be enabled or disabled as a "normal IRQ" source after a series of calls to {en,dis}able_irq(). For shared IRQs, the IRQ must be enabled so long as at least one driver needs it active. Likewise, IRQs need the same support to track whether the IRQ should be enabled or disabled as a "wakeup event" source after a series of calls to {en,dis}able_irq_wake(). For shared IRQs, the IRQ must be enabled as a wakeup source during sleep so long as at least one driver needs it. But right now they _don't have_ that refcounting ... which means sharing a wakeup-capable IRQ can't work correctly in some configurations. This patch adds the refcount and flag mechanisms to set_irq_wake() -- which is what {en,dis}able_irq_wake() call -- and minimal documentation of what the irq wake mechanism does. Drivers relying on the older (broken) "toggle" semantics will trigger a warning; that'll be a handful of drivers on ARM systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | Events sent by Process Events Connector from a 64-bit kernel are not binary compatible with a 32-bit userspace program because the "timestamp" field (struct timespec) is not arch independent. This affects the fields that follow "timestamp" as they will be be off by 8 bytes. This is a problem for 32-bit userspace programs running with 64-bit kernels on ppc64, s390, x86-64.. any "biarch" system. Matt had submitted a different solution to lkml as an RFC earlier. We have since switched to a solution recommended by Evgeniy Polyakov. This patch fixes the problem by changing the timestamp to be a __u64, which stores the number of nanoseconds. Tested on a x86_64 system with both 32 bit application and 64 bit application and on a i386 system.

* [PATCH] ext3: avoid triggering ext3_error on bad NFS file handleNeil Brown2006-07-313-8/+29
| | | | | | | | | | | | | | | | | | | | | The inode number out of an NFS file handle gets passed eventually to ext3_get_inode_block() without any checking. If ext3_get_inode_block() allows it to trigger an error, then bad filehandles can have unpleasant effect - ext3_error() will usually cause a forced read-only remount, or a panic if `errors=panic' was used. So remove the call to ext3_error there and put a matching check in ext3/namei.c where inode numbers are read off storage.

* | [PATCH] x86_64: Calgary IOMMU - Multi-Node NULL pointer dereference fixJon Mason2006-07-303-40/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calgary hits a NULL pointer dereference when booting in a multi-chassis NUMA system. See Redhat bugzilla number 198498, found by Konrad Rzeszutek (konradr@redhat.com). There are many issues that had to be resolved to fix this problem. Firstly when I originally wrote the code to handle NUMA systems, I had a large misunderstanding that was not corrected until now. That was that I thought the "number of nodes online" referred to number of physical systems connected. So that if NUMA was disabled, there would only be 1 node and it would only show that node's PCI bus. In reality if NUMA is disabled, the system displays all of the connected chassis as one node but is only ignorant of the delays in accessing main memory. Therefore, references to num_online_nodes() and MAX_NUMNODES are incorrect and need to be set to the maximum number of nodes that can be accessed (which are 8). I created a variable, MAX_NUM_CHASSIS, and set it to 8 to fix this. Secondly, when walking the PCI in detect_calgary, the code only checked the first "slot" when looking to see if a device is present. This will work for most cases, but unfortunately it isn't always the case. In the NUMA MXE drawers, there are USB devices present on the 3rd slot (with slot 1 being empty). So, to work around this, all slots (up to 8) are scanned to see if there are any devices present. Lastly, the bus is being enumerated on large systems in a different way the we originally thought. This throws the ugly logic we had out the window. To more elegantly handle this, I reorganized the kva array to be sparse (which removed the need to have any bus number to kva slot logic in tce.c) and created a secondary space array to contain the bus number to phb mapping. With these changes Calgary boots on an x460 with 4 nodes with and without NUMA enabled.
