c401110186 IDE: remove rwsem use from ide-proc core
The subsystem rwsem is not used by the driver core at all, so the use of
it in the ide-proc code of it doesn't make any sense.  Perhaps a local
lock might be needed, but I do not really think so.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

2b8693c061 [PATCH] mark struct file_operations const 3
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

b653d081c1 [PATCH] proc: remove useless (and buggy) ->nlink settings
Bug: pnx8550 code creates directory but resets ->nlink to 1.

create_proc_entry() et al will correctly set ->nlink for you.

8604affde9 [PATCH] convert IDE device drivers to driver-model
* add ide_bus_match() and export ide_bus_type
* split ide_remove_driver_from_hwgroup() out of ide_unregister()
* move device cleanup from ide_unregister() to drive_release_dev()
* convert ide_driver_t->name to driver->name
* convert ide_driver_t->{attach,cleanup} to driver->{probe,remove}
* remove ide_driver_t->busy as ide_bus_type->subsys.rwsem
  protects against concurrent ->{probe,remove} calls
* make ide_{un}register_driver() void as it cannot fail now
* use driver_{un}register() directly, remove ide_{un}register_driver()
* use device_register() instead of ata_attach(), remove ata_attach()
* add proc_print_driver() and ide_drivers_show(), remove ide_drivers_op
* fix ide_replace_subdriver() and move it to ide-proc.c
* remove ide_driver_t->drives, ide_drives and drives_lock
* remove ide_driver_t->drivers, drivers and drivers_lock
* remove ide_drive_t->driver and DRIVER() macro

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!
