Russell King investigated a failure case I introduced: When booting
with "load_ramdisk=1", we use the kernel root= parameter to determine
from what device to get the contents to copy into a ramdisk and then
mount that ramdisk as root.

For the copy to work, /dev/root needs to point to the device to load the
ramdisk from.

This happens if you have encountered a compile error in a module.
In this case you did not succeed the compilation of fs/binfmt_aout,
and therefore no .o file can be located.
kbuild assumes this is because you have messed with SUBDIRS, which is wrong.

s390x has a reference to _GLOBAL_OFFSET_TABLE_ in each module
that is resolved by the module loader. This patch prevents
modpost from emitting a warning about that symbol.

Create a nice shorthand to enable the non-verbose output mode.
make V=1        => Gives verbose output (default)
make V=0        => Gives non-verbose output

One of the reasons why people does not use KBUILD_VERBOSE=0 that
much is simply the typing needed.
This notation should make it acceptable to type it.
The usage of "make V=0" is restricted to the command line.
Anyone that wants to enable the non-verbose mode pr. default shall
set KBUILD_VERBOSE in the shell.

We warn when symbols end in __per_cpu, but aren't in the per-cpu section.
However, checksum symbols gave false positives.

Those were missing, not particularly harmful, but still needed for
correctness.

set -e is needed for each (continued) line.

Many places use inappropriate types for comparing jiffies,
int for example.  Fix those places up.

 - Cleanup Makefile.
 - Fix potentional crash in dv1394 module unload.
 - Why does ARM's memcpy not return void*? Oh well, work around it in
  eth1394 by not expecting standard behavior.

 - Inode and dcache Hash table only needs half the memory/cache because
   of using hlists.
 - Simplify dcache-rcu code.  With NULL end markers in the hlists
   is_bucket is not needed anymore.  Also the list walking code
   generates better code on x86 now because it doesn't need to dedicate
   a register for the list head.
 - Reorganize struct dentry to be more cache friendly.  All the state
   accessed for the hash walk is in one chunk now together with the
   inline name (all at the end)
 - Add prefetching for all the list walks.  Old hash lookup code didn't
   use it.
 - Some other minor cleanup.

Originally from Nikita Danliov. 

- Add struct subsystem to struct file_system_type. 
- Add fs_subsys_init() to explicitly call sysfs_init() very early.
- Register base fs subsystem then, too.
- Register filesystems' embedded subsystem when registered with fs core.

Resulting tree looks like:

# tree /sys/fs/
/sys/fs/
|-- bdev
|-- devpts
|-- eventpollfs
|-- ext2
|-- ext3
|-- futexfs
|-- iso9660
|-- pipefs
|-- proc
|-- ramfs
|-- rootfs
|-- sockfs
|-- sysfs
`-- tmpfs

- For matching registered platform devices with platform drivers.

- Also, make sure platform_bus is initialized early, with the rest of the 
  core stuff.

This ensures that sysfs is initialized very early, before anything can 
possibily registered with it. 

It happens early enough that all filesystems can registered with sysfs 
(besides sysfs itself), which is coming next.

- Call driver_init() from init/main.c::do_basic_setup(). 

This ensures that all the driver model subsystems are initialized before
any drivers or devices can be registered. 

It nearly frees up the core and postcore initcall levels, making them 
available for other kernel code to use freely. 

From Andrew Morton

- Add ioctl32 compat function registration for video1394, dv1394 and
  amdtp.
- Convert SBP-2 driver to new SCSI hotplug host/device interfaces.
- Initial Async ISO (GASP) support.

- Create and register kobjects when adding a cpu to the cpufreq interface,
  instead of the terminally broken struct intf_data.

- Remove struct intf_data. 
  It was silly, and gave us an unbalanced interface. 
  Instead, when removing a device_interface, all of a class's devices are
  iterated over, and intf->remove_device() is called for each. (Instead 
  of the device's list of interfaces it belongs to). 
  Interfaces are expected to tell if they support the device being removed.

- Remove struct device::intf_list.

- Protect classes' device list access with devclass_sem, which is taken 
  when a device or interface is added or removed. This allows access to the
  list w/o taking the class's lock, which allows subordinate objects to be
  registered (e.g. the interface itself, or objects the interfaces create
  for a device). 

- This should fix a deadlock when devices are added to interfaces, which 
  calls intf->add_device(), then interface_add_data(), which call 
  kobject_register() and hangs, since it tries to take the class's lock
  again. 

Check whether kset is NULL or not before doing container_of().

From Dominik Brodowski

From Matt Wilcox

If a file that doesn't exist was looked up in a directory, and that
directory is later removed, sysfs would reap the negative dentrys along 
with the valid ones.

Fix is to manually remove the dentrys from the parent's list under the 
dcache_lock, then check if they're valid with dget_locked(). 

This ensures all the dentrys are removed, valid and invalid, and we don't 
reap anything we shouldn't.
