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] 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.

2006-07-26[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.

2006-07-19[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.

2006-07-15[PATCH] per-task delay accounting taskstats interface: control exit data ↵Shailabh Nagar
through cpumasks On systems with a large number of cpus, with even a modest rate of tasks exiting per cpu, the volume of taskstats data sent on thread exit can overflow a userspace listener's buffers. One approach to avoiding overflow is to allow listeners to get data for a limited and specific set of cpus. By scaling the number of listeners and/or the cpus they monitor, userspace can handle the statistical data overload more gracefully. In this patch, each listener registers to listen to a specific set of cpus by specifying a cpumask. The interest is recorded per-cpu. When a task exits on a cpu, its taskstats data is unicast to each listener interested in that cpu. Thanks to Andrew Morton for pointing out the various scalability and general concerns of previous attempts and for suggesting this design.

2006-07-15[PATCH] per-task delay accounting: avoid send without listenersShailabh Nagar
Don't send taskstats (per-pid or per-tgid) on thread exit when no one is listening for such data. Currently the taskstats interface allocates a structure, fills it in and calls netlink to send out per-pid and per-tgid stats regardless of whether a userspace listener for the data exists (netlink layer would check for that and avoid the multicast). As a result of this patch, the check for the no-listener case is performed early, avoiding the redundant allocation and filling up of the taskstats structures.

2006-07-15[PATCH] delay accounting taskstats interface send tgid onceShailabh Nagar
Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP.

2006-07-15[PATCH] gpio: drop vtable members .gpio_set_high .gpio_set_low gpio_set is ↵Jim Cromie
enough drops gpio_set_high, gpio_set_low from the nsc_gpio_ops vtable. While we can't drop them from scx200_gpio (or can we?), we dont need them for new users of the exported vtable; gpio_set(1), gpio_set(0) work fine.

2006-07-15[PATCH] null-terminate over-long /proc/kallsyms symbolsAndreas Gruenbacher
Got a customer bug report (https://bugzilla.novell.com/190296) about kernel symbols longer than 127 characters which end up in a string buffer that is not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy prevents this from happening, even though such symbols still won't come out right. A better fix would be to not use a fixed-size buffer, but it's probably not worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

2006-07-15[PATCH] mm: fix oom roll-back of __vmalloc_area_nodeJan Kiszka
__vunmap must not rely on area->nr_pages when picking the release methode for area->pages. It may be too small when __vmalloc_area_node failed early due to lacking memory. Instead, use a flag in vmstruct to differentiate. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-14[VLAN]: __vlan_hwaccel_rx can use the faster ether_compare_addrStephen Hemminger
The inline function compare_ether_addr is faster than memcmp. Also, don't need to drag in proc_fs.h, the only reference to proc_dir_entry is a pointer so the declaration is needed here.

2006-07-13[PATCH] Fix broken kernel headers preventing ARM buildRussell King
As a result of 894673ee6122a3ce1958e1fe096901ba5356a96b, the ARM architecture is more or less unbuildable - only one defconfig appears to build, with all others erroring out with: CC arch/arm/kernel/setup.o In file included from /home/rmk/git/linux-2.6-rmk/arch/arm/kernel/setup.c:22: /home/rmk/git/linux-2.6-rmk/include/linux/root_dev.h:7: warning: implicit declaration of function `MKDEV' ... Essentially, root_dev.h uses MKDEV and dev_t, but does not include any headers which provide either of these definitions. The reason it worked previously is that linux/tty.h just happened to include the required headers for linux/root_dev.h.
