fe480a2675 Modules: only add drivers/ direcory if needed
This changes the module core to only create the drivers/ directory if we
are going to put something in it.

a416aba637 [PATCH] kernelparams: detect if and which parameter parsing enabled irq's
The parsing of some kernel parameters seem to enable irq's at a stage that
irq's are not supposed to be enabled (Particularly the ide kernel parameters).

Having irq's enabled before the irq controller is initialized might lead to a
kernel panic.  This patch only detects this behaviour and warns about wich
parameter caused it.

d10be6d1bd [PATCH] module_subsys: initialize earlier
Initialize module_subsys earlier (or at least earlier than devices) since
it could be used very early in the boot process if kmod loads a module
before the device initcalls.  Otherwise, kmod will crash in
kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not
initialized yet.

I only noticed this problem because occasionally, kmod loads the modules
for my SCSI and Ethernet adapters very early, during the boot process
itself.  I don't quite understand why it loads them sometimes and doesn't
load them other times.  Or who is telling kmod to do so.  Can someone
explain?

b9e20a9200 [PATCH] Change dash2underscore() return value to char
Since dash2underscore() just operates and returns chars, I guess its safe
to change the return value to a char.  With my .config, this reduces its
size by 5 bytes.

03e88ae1b1 [PATCH] fix module sysfs files reference counting
The module files, refcnt, version, and srcversion did not properly
increment the owner's module reference count, allowing the modules to
be removed while the files were open, causing oopses.

This patch fixes this, and also fixes the problem that the version and
srcversion files were not showing up, unless CONFIG_MODULE_UNLOAD was
enabled, which is not correct.

9e28393998 [PATCH] kernel/params.c: fix sysfs access with CONFIG_MODULES=n
All the work was done to setup the file and maintain the file handles but
the access functions were zeroed out due to the #ifdef.  Removing the
#ifdef allows full access to all the parameters when CONFIG_MODULES=n.

akpm: put it back again, but use CONFIG_SYSFS instead.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

31143a1204 [PATCH] kernel/param.c: don't use .max when .num is NULL in param_array_set()
there seems to be a bug, at least for me, in kernel/param.c for arrays with
.num == NULL.  If .num == NULL, the function param_array_set() uses &.max
for the call to param_array(), wich alters the .max value to the number of
arguments.  The result is, you can't set more array arguments as the last
time you set the parameter.

example:

# a module 'example' with
# static int array[10] = { 0, };
# module_param_array(array, int, NULL, 0644);

$ insmod example.ko array=1,2,3
$ cat /sys/module/example/parameters/array
1,2,3
$ echo "4,3,2,1" > /sys/module/example/parameters/array
$ dmesg | tail -n 1
kernel: array: can take only 3 arguments

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
