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.

with the following config:

the reason for the build failure is the duplicate definition of the

The duplication was a merge error: it was added via -mm by commit
v2.6.25-7262-g2850699c, "sysfs: sysfs_update_group stub for
CONFIG_SYSFS=n" a day before v2.6.26-rc1, but a day before that the same

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.

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.
