2008-05-05kgdb: 1000 loops for the single step test in kgdbtsJason Wessel
The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.

2008-05-04Make forced module loading optionalLinus Torvalds
The kernel module loader used to be much too happy to allow loading of modules for the wrong kernel version by default. For example, if you had MODVERSIONS enabled, but tried to load a module with no version info, it would happily load it and taint the kernel - whether it was likely to actually work or not! Generally, such forced module loading should be considered a really really bad idea, so make it conditional on a new config option (MODULE_FORCE_LOAD), and make it default to off. If somebody really wants to force module loads, that's their problem, but we should not encourage it. Especially as it happened to me by mistake (ie regular unversioned Fedora modules getting loaded) causing lots of strange behavior. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-04x86: remove dell reboot dmi quirk board name matchBen
http://bugzilla.kernel.org/show_bug.cgi?id=10547 Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'. A patch for some versions of the OptiPlex was proposed here -- http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and later kernels, according to http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However, the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest adding another clause to reboot.c, similar to the one in the original patch, but matching a DMI_BOARD_NAME of "0RF703". On further inspection, it seems that there are other DMI_BOARD_NAMEs for this same machine. They seem to change from time to time, which means that the current code is fragile. Moreover, using bios reboot should not break non-SFF OptiPlex 745s, and so a reasonable fix is to simply drop the match on DMI_BOARD_NAME.

2008-05-04modpost: i2c aliases need no trailing wildcardJean Delvare
Not all device types need a wildcard at the end of their module aliases. In particular, for i2c module aliases, the trailing wildcard is not only unneeded, it could also cause the wrong driver to be loaded. As I2C devices have no IDs, i2c module aliases are simple, arbitrary device names. For example: $ /sbin/modinfo lm90 filename: /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko author: Jean Delvare <khali@linux-fr.org> description: LM90/ADM1032 driver license: GPL vermagic: 2.6.25-git18 mod_unload depends: hwmon alias: i2c:lm90* alias: i2c:adm1032* alias: i2c:lm99* alias: i2c:lm86* alias: i2c:max6657* alias: i2c:adt7461* alias: i2c:max6680* $ This would cause trouble if one I2C chip name matches the beginning of another I2C chip name and both chips are supported by different drivers. For example, an i2c device named lm9042 would cause the lm90 driver to be loaded, while it doesn't support that device. This case has yet to be seen in practice, but still, I'd like to fix it now. The cleanest fix is to remove the trailing wildcard from i2c module aliases. Here's a patch doing this. Not all device type aliases need a trailing wildcard, in particular the i2c aliases don't. Don't add a wildcard by default in do_table(), instead let each device type handler add it if needed. I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci, pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of, vio, parisc, sdio and virtio) are untested.

2008-05-03tiny mq_open optimizationUlrich Drepper
A very small cleanup for mq_open. We do not have to call set_close_on_exit if we create the file descriptor right away with the flag set. We have a function for this now. The resulting code is smaller and a tiny bit faster. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-05-03unified (weak) sys_pipe implementationUlrich Drepper
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
