We had two major issues when unregistering networking devices.
1) Even trying to run hotplug asynchronously could deadlock
if keventd was currently trying to get the RTNL semaphore
in order to process linkwatch events.
2) Unregister needs to wait for the last reference to go away
before the finalization of the unregister can execute. This
cannot occur under the RTNL semaphore as this is deadlock
prone as well.
The solution is to do all of this stuff after dropping the
RTNL semaphore. rtnl_lock, if it is about to protect a region
of code that could unregister network devices, registers a list
to which unregistered netdevs are attached. At rtnl_unlock time
this list is processed to wait for refcounts to drop to zero and
then finalize the unregister.

From: Russell Miller <rmiller@duskglow.com>
A BUG or an oops will often leave a machine in a useless state. There is no
way to remotely recover the machine from that state.
The patch adds a /proc/sys/kernel/panic_on_oops sysctl which, when set, will
cause the x86 kernel to call panic() at the end of the oops handler. If the
user has also set /proc/sys/kernel/panic then a reboot will occur.
The implementation will try to sleep for a while before panicing so the oops
info has a chance of hitting the logs.
The implementation is designed so that other architectures can easily do this
in their oops handlers.

This patch moves BUG() and PAGE_BUG() from asm/page.h into asm/bug.h.
We also fix up linux/dcache.h, which included asm/page.h for the sole
purpose of getting the BUG() definition.
Since linux/kernel.h and linux/smp.h make use of BUG(), asm/bug.h is
included there as well.
In addition, linux/jbd.h did not contain a clear path with which to
obtain the archtecture BUG() definition, but did contain its own
definition.

Various archs (i386, m68k, s390, s390x, m68k, parisc, um, x86_64)
implement kernel_text_address. Put this in kernel/extable.c, and the
module iteration inside module.c.
Other than cleanliness, this finally allows the module list and lock
to be static to kernel/module.c (you didn't think I actually cared
about those archs did you?)
It also drops the module->init_size to zero when it's discarded, so
bounds checking is simplified (and the /proc/modules size statistic
will be more accurate, too).

This implements EXPORT_SYMBOL_GPL and MODULE_LICENSE properly (so
restrictions are enforced). Also fixes "proprietory" spelling.

ALIGN() currently has global scope in <linux/cache.h>. This causes a
compilation error in the defxx driver.
Move ALIGN() to <linux/kernel.h> and change the defxx driver to use the
generic macro in place of its own.

This patch is a rewrite of the insmod and boot parameter handling,
to unify them.
The new format is fairly simple: built on top of __module_param_call there
are several helpers, eg "module_param(foo, int, 000)". The final argument
is the permissions bits, for exposing parameters in sysfs (if
non-zero) at a later stage.

Moves console_loglevel & friends to an array, as sysctl expects.

|
This makes the sleep-under-spinlock-held check a CONFIG_ option.
|
|
This is the logical counterpoint to the code which marks modules
"[unsafe]" when obsolete (racy) interfaces are used. Allows "just
remove the damn thing" rmmod -f, and taints the kernel.
Mark it dangerous and experimental in the config file to make this
doubly clear.

kill the machine.
Damn I hate people who kill the machine for no good reason.

[This has four scalps already. Thomas Molina has agreed
to track things as they are identified ]
Infrastructure to detect sleep-inside-spinlock bugs. Really only
useful if compiled with CONFIG_PREEMPT=y. It prints out a whiny
message and a stack backtrace if someone calls a function which might
sleep from within an atomic region.
This patch generates a storm of output at boot, due to
drivers/ide/ide-probe.c:init_irq() calling lots of things which it
shouldn't under ide_lock.
It'll find other bugs too.

From Christoph Hellwig, also present in 2.4.
Create an arch-independent `dump_stack()' function. So we don't need to do
#ifdef CONFIG_X86
show_stack(0); /* No prototype in scope! */
#endif
any more.
The whole dump_stack() implementation is delegated to the architecture.
If it doesn't provide one, there is a default do-nothing library
function.

some more pasters..

Define container_of which cast from member to struct with some type checking.
This is much like list_entry but is cearly for things other than lists.
List_entry now uses container_of.
|
|
Newer Athlons have means of checking if they are SMP capable or not.
This code adds checks that printk a warning on systems not intended
for SMP, and set the taint flag that modutils is already aware of.
The taint code is also improved to use defines instead of magic numbers.
