2006-08-02usb-storage: Add US_FL_IGNORE_DEVICE flag; ignore ZyXEL G220FDaniel Drake
This patch adds a new unusual_devs flag for when usb-storage needs to ignore a device that it would otherwise claim. We need to ignore the ZyXEL G220F as it is a virtual CDROM drive which includes the windows driver for this USB-WLAN adapter. After the windows driver is installed on a windows system, it converts it into a WLAN adapter (by ejecting the virtual disc). The virtual CDROM is of no interest to Linux users. The zd1211rw driver will automatically perform the eject operation, we just need to ensure that usb-storage does not claim the device.

2006-07-31[PATCH] powermac: More powermac backlight fixesMichael Hanselmann
This patch fixes several problems: - The legacy backlight value might be set at interrupt time. Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.

2006-07-31[PATCH] fbdev: statically link the framebuffer notification functionsAntonino A. Daplas
The backlight and lcd subsystems can be notified by the framebuffer layer of blanking events. However, these subsystems, as a whole, can function independently from the framebuffer layer. But in order to enable to the lcd and backlight subsystems, the framebuffer has to be compiled also, effectively sucking in a huge amount of unneeded code. To prevent dependency problems, separate out the framebuffer notification mechanism from the framebuffer layer and permanently link it to the kernel.

2006-07-31[PATCH] delay accounting: temporarily enable by defaultShailabh Nagar
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.

2006-07-31[PATCH] genirq: {en,dis}able_irq_wake() need refcounting tooDavid Brownell
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.

2006-07-31[PATCH] Process Events: Fix biarch compatibility issue. use __u64 timestampChandra Seetharaman
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.

2006-07-31[PATCH] ext3: avoid triggering ext3_error on bad NFS file handleNeil Brown
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.

2006-07-29[PATCH] x86_64: Calgary IOMMU - Multi-Node NULL pointer dereference fixJon Mason
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.

2006-07-28[PATCH] pi-futex: robust-futex exitIngo Molnar
Fix robust PI-futexes to be properly unlocked on unexpected exit. For this to work the kernel has to know whether a futex is a PI or a non-PI one, because the semantics are different. Since the space in relevant glibc data structures is extremely scarce, the best solution is to encode the 'PI' information in bit 0 of the robust list pointer. Existing (non-PI) glibc robust futexes have this bit always zero, so the ABI is kept. New glibc with PI-robust-futexes will set this bit.

2006-07-28[PATCH] x86_64: Enlarge debug stack for nested kprobesbibo mao
In x86_64 platform, INT1 and INT3 trap stack is IST stack called DEBUG_STACK, when INT1/INT3 trap happens, system will switch to DEBUG_STACK by hardware. Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested, it will destroy other vector's IST stack. This patch modifies this, it sets DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap. Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed by other kprobes. Thanks jbeulich for pointing out error in the first patch. [AK: nested kprobes are pretty dubious. Hopefully one nest will be enough.

2006-07-26[PATCH] Reorganize the cpufreq cpu hotplug locking to not be totally bizareArjan van de Ven
The patch below moves the cpu hotplugging higher up in the cpufreq layering; this is needed to avoid recursive taking of the cpu hotplug lock and to otherwise detangle the mess. The new rules are: 1. you must do lock_cpu_hotplug() around the following functions: __cpufreq_driver_target __cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only) __cpufreq_set_policy 2. governer methods (.governer) must NOT take the lock_cpu_hotplug() lock in any way; they are called with the lock taken already 3. if your governer spawns a thread that does things, like calling __cpufreq_driver_target, your thread must honor rule #1. 4. the policy lock and other cpufreq internal locks nest within the lock_cpu_hotplug() lock. I'm not entirely happy about how the __cpufreq_governor rule ended up (conditional locking rule depending on the argument) but basically all callers pass this as a constant so it's not too horrible. The patch also removes the cpufreq_governor() function since during the locking audit it turned out to be entirely unused (so no need to fix it) The patch works on my testbox, but it could use more testing (otoh... it can't be much worse than the current code) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-23cpu hotplug: simplify and hopefully fix lockingLinus Torvalds
The CPU hotplug locking was quite messy, with a recursive lock to handle the fact that both the actual up/down sequence wanted to protect itself from being re-entered, but the callbacks that it called also tended to want to protect themselves from CPU events. This splits the lock into two (one to serialize the whole hotplug sequence, the other to protect against the CPU present bitmaps changing). The latter still allows recursive usage because some subsystems (ondemand policy for cpufreq at least) had already gotten too used to the lax locking, but the locking mistakes are hopefully now less fundamental, and we now warn about recursive lock usage when we see it, in the hope that it can be fixed.

2006-07-21[SPARC64]: Fix more of_device layer IRQ bugs, and correct PROMREG_MAX.David S. Miller
Sabre and Psycho PCI controllers can have partial interrupt-map properties, meaning that on-board devices don't match up to any entries. Instead, they are fully specified from the beginning and we should pass them directly to the IRQ translator as-is. Also, fill in the necessary translator slots for the "graphics" and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS. Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices. Finally, prevent accidentally writing past the end of the of_device struct resource[] and irqs[] arrays. Spit out a log message when we ignore some entries because there are too many of them.

2006-07-19[PATCH] libata: improve EH action and EHI flag handlingTejun Heo
Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and EHI flag handling. * There are two types of EHI flags - one which expires on successful EH and the other which expires on a successful reset. Make this distinction clear. * Unlike other EH actions, reset actions are represented by two EH action masks and a EHI modifier. Implement correct about_to_do/done semantics for resets. That is, prior to reset, related EH info is sucked in from ehi and cleared, and after reset is complete, related EH info in ehc is cleared. These changes improve consistency and remove unnecessary EH actions caused by stale EH action masks and EHI flags.

2006-07-14[PATCH] remove set_wmb - arch removalSteven Rostedt
set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
