There are cases in which a device's memory mapped registers overlap with another device's memory mapped registers. On several PowerPC devices this occurs for the MDIO bus, whose registers tended to overlap with one of the ethernet controllers. By switching from request_resource to insert_resource we can register the MDIO bus as a proper platform device and not hack around how we handle its memory mapped registers.

The klist reference counting in the find functions that use klist_iter_init_node is broken. If the function (for example driver_find_device) is called with a NULL start object then everything is fine, the first call to next_device()/klist_next increases the ref-count of the first node on the list and does nothing for the start object which is NULL. If they are called with a valid start object then klist_next will decrement the ref-count for the start object but nobody has incremented it. Logical place to fix this would be klist_iter_init_node because the function puts a reference of the object into the klist_iter struct.

This patch (as604) makes the driver core hold a device's parent's lock as well as the device's lock during calls to the probe and remove methods in a driver. This facility is needed by USB device drivers, owing to the peculiar way USB devices work: A device provides multiple interfaces, and drivers are bound to interfaces rather than to devices; Nevertheless a reset, reset-configuration, suspend, or resume affects the entire device and requires the caller to hold the lock for the device, not just a lock for one of the interfaces. Since a USB driver's probe method is always called with the interface lock held, the locking order rules (always lock parent before child) prevent these methods from acquiring the device lock. The solution provided here is to call all probe and remove methods, for all devices (not just USB), with the parent lock already acquired. Although currently only the USB subsystem requires these changes, people have mentioned in prior discussion that the overhead of acquiring an extra semaphore in all the prove/remove sequences is not overly large. Up to now, the USB core has been using its own set of private semaphores. A followup patch will remove them, relying entirely on the device semaphores provided by the driver core. The code paths affected by this patch are: device_add and device_del: The USB core already holds the parent lock, so no actual change is needed. driver_register and driver_unregister: The driver core will now lock both the parent and the device before probing or removing. driver_bind and driver_unbind (in sysfs): These routines will now lock both the parent and the device before binding or unbinding. bus_rescan_devices: The helper routine will lock the parent before probing a device. I have not tested this patch for conflicts with other subsystems. As far as I can see, the only possibility of conflict would lie in the bus_rescan_devices pathway, and it seems pretty remote. Nevertheless, it would be good for this to get a lot of testing in -mm. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The distinction between hotplug and uevent does not make sense these days, netlink events are the default. udev depends entirely on netlink uevents. Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now. Signed-off-by: NKay Sievers <kay.sievers@suse.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The names of these events have been confusing from the beginning on, as they have been more like claim/release events. We needed these events for noticing HAL if storage devices have been mounted. Thanks to Al, we have the proper solution now and can poll() /proc/mounts instead to get notfied about mount tree changes.

This deprecates the /proc/sys/kernel/hotplug file, as all this stuff should be in /sys some day, right? :) In /sys/kernel/ we have now uevent_seqnum and uevent_helper. The seqnum is no longer used by udev, as the version for this kernel depends on netlink which events will never get out-of-order. Recent udev versions disable the /sbin/hotplug helper with an init script, cause it leads to OOM on big boxes by running hundreds of shells in parallel. It should be done now by: echo "" > /sys/kernel/uevent_helper (Note that "-n" does not work, cause neighter proc nor sysfs support truncate().)

These days we use udev to manage all kernel events. /proc/sys/kernel/hotplug will usually be disabled by an init-script. pnpnbios is not integrated with the driver core and should stay away from the now disabled /sbin/hotplug. Set the helper to /sbin/phpbios, even when there is probably no current user of this faciliy. If it's needed, it should definitely get proper driver core integration instead of forking binaries from the kernel.

In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64 <asm/param.h> was changed to include <linux/config.h> for the configurable timer frequency. However, asm/param.h is sometimes used in userland (it is included indirectly from <sys/param.h>), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros. This greatly confuses software packages (such as BusyBox) which use CONFIG_FOO macros themselves to control the inclusion of optional features.

Some G5s still occasionally experience shutdowns due to overtemp conditions despite the recent fix. After analyzing logs from such machines, it appears that the overtemp code is a bit too quick at shutting the machine down when reaching the critical temperature (tmax + 8) and doesn't leave the fan enough time to actually cool it down. This happens if the temperature of a CPU suddenly rises too high in a very short period of time, or occasionally on boot (that is the CPUs are already overtemp by the time the driver loads). This patches makes the code a bit more relaxed, leaving a few seconds to the fans to do their job before kicking the machine shutown.

This is a slightly more complete fix for the previous minimal sysctl string fix. It always terminates the returned string with a NUL, even if the full result wouldn't fit in the user-supplied buffer. The returned length is the full untruncated length, so that you can tell when truncation has occurred. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

For the sysctl syscall, if the user wants to get the old value of a sysctl entry and set a new value for it in the same syscall, the old value is always overwritten by the new value if the sysctl entry is of string type and if the user sets its strategy to sysctl_string. This issue lies in the strategy being run twice if the strategy is set to sysctl_string, the general strategy sysctl_string always returns 0 if success. Such strategy routines as sysctl_jiffies and sysctl_jiffies_ms return 1 because they do read and write for the sysctl entry. The strategy routine sysctl_string return 0 although it actually read and write the sysctl entry. According to my analysis, if a strategy routine do read and write, it should return 1, if it just does some necessary check but not read and write, it should return 0, for example sysctl_intvec.

The old /proc interfaces were never updated to use loff_t, and are just generally broken. Now, we should be using the seq_file interface for all of the proc files, but converting the legacy functions is more work than most people care for and has little upside.. But at least we can make the non-LFS rules explicit, rather than just insanely wrapping the offset or something. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This reverts the series of commits 67dbb4ea 281ab031 47807ce3 that changed the GART VM start offset. It fixed some machines, but seems to continually interact badly with some X versions. Quoth Ben Herrenschmidt: "So I think at this point, the best is that we keep the old bogus code that at least is consistent with the bug in the server. I'm working on a big patch to X that reworks the memory map stuff completely and fixes those issues on the server side, I'll do a DRM patch matching this X fix as well so that the memory map is only ever set in one place and with what I hope is a correct algorithm..."

Don't use printk() where "current_thread_info()" is crap. Until when we switch to running on init_stack, current_thread_info() evaluates to crap. Printk uses "current" at times (in detail, ¤t is evaluated with CONFIG_DEBUG_SPINLOCK to check the spinlock owner task). And this leads to random segmentation faults. Exactly, what happens is that ¤t = *(current_thread_info()), i.e. round down $esp and dereference the value. I.e. access the stack below $esp, which causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).
