* [PATCH] don't freeze firewire on suspend.Dave Jones2006-01-061-2/+2
| | | | | | | | | | | | | We had a report from one loony user who tried out suspend to disk using a swap partition on a firewire drive. As the firewire thread was put to sleep it didn't work out too well.

* [PATCH] x86: Fixed pnp bios limitsZachary Amsden2006-01-061-11/+4
| | | | | | | | | | | | | | | | PnP BIOS data, code, and 32-bit entry segments all have fixed limits as well; set them in the GDT rather than adding more code. It would be nice to add these fixups to the boot GDT rather than setting the GDT for each CPU; perhaps I can wiggle this in later, but getting it in before the subsys init looks tricky. Also, make some progress on deprecating the ugly Q_SET_SEL macros.

* [PATCH] x86: Pnp byte granularityZachary Amsden2006-01-061-1/+4
| | | | | | | | | | | | | | | | | | | | | | | The one remaining caller of set_limit, the PnP BIOS code, calls into the PnP BIOS, passing kernel parameters in and out. These parameteres may be passed from arbitrary kernel virtual memory, so they deserve strict protection to stop a bad BIOS from smashing beyond the object size. Unfortunately, the use of set_limit was badly botching this by setting the limit in terms of pages, when it really should have byte granularity. When doing this, I discovered my BIOS had the buggy code during the "get system device node" call: mov ax, es:[bx] Which is harmless, but has a trivial workaround.

* [PATCH] x86: GDT alignment fixZachary Amsden2006-01-061-9/+13
| | | | | | | | | | | | | | | | Make GDT page aligned and page padded to support running inside of a hypervisor. This prevents false sharing of the GDT page with other hot data, which is not allowed in Xen, and causes performance problems in VMware. Rather than go back to the old method of statically allocating the GDT (which wastes unneded space for non-present CPUs), the GDT for APs is allocated dynamically.

* [PATCH] nbd: fix TX/RX race conditionHerbert Xu2006-01-061-62/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Janos Haar of First NetCenter Bt. reported numerous crashes involving the NBD driver. With his help, this was tracked down to bogus bio vectors which in turn was the result of a race condition between the receive/transmit routines in the NBD driver. The bug manifests itself like this: CPU0 CPU1 do_nbd_request add req to queuelist nbd_send_request send req head for each bio kmap send nbd_read_stat nbd_find_request nbd_end_request kunmap When CPU1 finishes nbd_end_request, the request and all its associated bio's are freed. So when CPU0 calls kunmap whose argument is derived from the last bio, it may crash. Under normal circumstances, the race occurs only on the last bio. However, if an error is encountered on the remote NBD server (such as an incorrect magic number in the request), or if there were a bug in the server, it is possible for the nbd_end_request to occur any time after the request's addition to the queuelist. The following patch fixes this problem by making sure that requests are not added to the queuelist until after they have been completed transmission. In order for the receiving side to be ready for responses involving requests still being transmitted, the patch introduces the concept of the active request. When a response matches the current active request, its processing is delayed until after the tranmission has come to a stop. This has been tested by Janos and it has been successful in curing this race condition. From: Herbert Xu <herbert@gondor.apana.org.au> Here is an updated patch which removes the active_req wait in nbd_clear_queue and the associated memory barrier. I've also clarified this in the comment.

| * [PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATEZach Brown2006-01-032-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | readpage(), prepare_write(), and commit_write() callers are updated to understand the special return code AOP_TRUNCATED_PAGE in the style of writepage() and WRITEPAGE_ACTIVATE. AOP_TRUNCATED_PAGE tells the caller that the callee has unlocked the page and that the operation should be tried again with a new page. OCFS2 uses this to detect and work around a lock inversion in its aop methods. There should be no change in behaviour for methods that don't return AOP_TRUNCATED_PAGE. WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are made enums so that kerneldoc can be used to document their semantics. Signed-off-by: Zach Brown <zach.brown@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCMCIA sockets have statically mapped memory windows, but dynamically mapped IO windows. Using the "nonstatic" socket library is inpractical for them, as they do neither need a resource database (as we can trust the kernel resource database on m68k and ppc) nor lots of other features of that library.

As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility.

With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

Some of the problems I ran into were distorted video when the console was active (missing first character, skipped dots) and when running X windows (colored snow, stripes, missing pixels). A quick examination of the 2.6 versus 2.4 source for the ATY driver revealed alot of changes. A closer look at the code/data for the 64GR/XL chip revealed two minor "typos" that the rewriter(s) of the code made. The first is a incorrect clock value (230 .vs. 235) and the second is a missing flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have fixed my problem. I tend to think the 235 value is the correct one, as there is a 29.4 Mhz clock crystal close to the video chip and 235.2 (29.4*8) is too close to 235 to make it a coincidence. The flag for M64F_SDRAM_MAGIC_PLL was dropped during the changes made by adaplas in file revision 1.72 on the old bitkeeper repository. The change relating to the clock rate has been there forever, at least in the 2.6 tree. I'm not sure where to look for the old 2.5 tree or if anyone cares when it happened. On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL properly for the DRAM. Signed-off-by: Luis F. Ortiz <lfo@Polyad.Org> Signed-off-by: David S.

It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and ide-tape, to autoload these modules depending on the probed media type of the IDE device. It is used by udev and replaces the former agent shell script of the hotplug package, which was required to lookup the media type in the proc filesystem. Using proc was racy, cause the media file is created after the hotplug event is sent out. The module autoloading does not take any effect, until something like the following udev rule is configured: SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}" The module ide-scsi will not be autoloaded, cause it requires manual configuration. It can't be, and never was supported for automatic setup in the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported media types, would just lead to a default blacklist entry anyway. $ modinfo ide-disk filename: /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko description: ATA DISK Driver alias: ide:*m-disk* license: GPL ... $ modprobe -vn ide:m-disk insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko $ cat /sys/bus/ide/devices/0.0/modalias ide:m-disk It also adds attributes to the IDE device: $ tree /sys/bus/ide/devices/0.0/ /sys/bus/ide/devices/0.0/ |-- bus -> ../../../../../../../bus/ide |-- drivename |-- media |-- modalias |-- power | |-- state | `-- wakeup `-- uevent $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media} ide:m-disk hda disk Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| | * | [PATCH] Allow overlapping resources for platform devicesKumar Gala2006-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * | [PATCH] Hold the device's parent's lock during probe and removeAlan Stern2006-01-042-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The other three files changed are blind changes of all remaining bus_type.hotplug references I could find to bus_type.uevent.
