429722e19d Input: Mac button emulation - allow compiling as a module
Not all systems require Mac-style button emulation, however distributions
enable it by default so it is readily available. Allow compiling it as a
module so it can be loaded only on systems that actually require it.

99b089c3c3 Input: Mac button emulation - implement as an input filter
Current implementation of Mac mouse button emulation plugs into legacy
keyboard driver, converts certain keys into button events on a separate
device, and suppresses the real events from reaching tty. This worked
well enough until user space started using evdev which was completely
unaware of this arrangement and kept sending original key presses to
its users. Change the implementation to use newly added input filter
framework so that original key presses are not transmitted to any
handlers.

As a bonus remove SYSCTL dependencies from the code and use Kconfig
instead; also do not create the emulated mouse device until user
activates emulation.

6d4561110a sysctl: Drop & in front of every proc_handler.
For consistency drop & in front of every proc_handler.  Explicity
taking the address is unnecessary and it prevents optimizations
like stubbing the proc_handlers to NULL.

894d249115 sysctl drivers: Remove dead binary sysctl support
Now that sys_sysctl is a wrapper around /proc/sys all of
the binary sysctl support elsewhere in the tree is
dead code.

8fd76c4506 Input: mac_hid - add lockdep annotation to emumousebtn
The mouse button emulation calls input device methods from an input
device. This causes funny lock nesting which is harmless as each
device has its own locks.

Give the nesting device its own lock classes so that lockdep will not
consider them the same.

7b19ada2ed get rid of input BIT* duplicate defines
get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

drivers/char/keyboard.c: In function 'kbd_keycode':
drivers/char/keyboard.c:1142: error: implicit declaration of function 'mac_hid_mouse_emulate_buttons'

The forward declaration of mac_hid_mouse_emulate_buttons() is not visible on
m68k because it's hidden in the middle of a big #ifdef block.

Move it to <linux/kbd_kern.h>, correct the type of the second parameter, and
include <linux/kbd_kern.h> where needed.

0b4d414714 [PATCH] sysctl: remove insert_at_head from register_sysctl
The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

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!
