Clean up the edd.c driver.

* use kobject_set_name() instead of snprintf() per GregKH's recommendation.
* Add MODULE_VERSION()
* s/driverfs/sysfs/ in Kconfig
* Remove report URL message, as there have been too many BIOSs reported,
  virtually none of which are EDD-capable.  This may return if/when I
  develop a better reporting method and database to capture/store the
  data from users.
* Remove the unused code for creating a symlink to the scsi_device.
  This never worked right, and I'm going to show the relationship from
  a userspace tool which uses libsysfs instead.

kblockd is the thread which runs unplug functions, not keventd.

The patch below moves the ppc64 spinlocks and rwlocks out of line and into
arch/ppc64/lib/locks.c, and implements _raw_spin_lock_flags for ppc64.

Part of the motivation for moving the spinlocks and rwlocks out of line was
that I needed to add code to the slow paths to yield the processor to the
hypervisor on systems with shared processors.  On these systems, a cpu as
seen by the kernel is a virtual processor that is not necessarily running
full-time on a real physical cpu.  If we are spinning on a lock which is
held by another virtual processor which is not running at the moment, we
are just wasting time.  In such a situation it is better to do a hypervisor
call to ask it to give the rest of our time slice to the lock holder so
that forward progress can be made.

The one problem with out-of-line spinlock routines is that lock contention
will show up in profiles in the spin_lock etc.  routines rather than in the
callers, as it does with inline spinlocks.  I have added a CONFIG_SPINLINE
config option for people that want to do profiling.  In the longer term, Anton
is talking about teaching the profiling code to attribute samples in the spin
lock routines to the routine's caller.

This patch reduces the kernel by about 80kB on my G5.  With inline
spinlocks selected, the kernel gets about 4kB bigger than without the
patch, because _raw_spin_lock_flags is slightly bigger than _raw_spin_lock.

This patch depends on the patch from Keith Owens to add
_raw_spin_lock_flags.

From: Keith Owens <kaos@sgi.com>

As requested by Linus, update all architectures to add the common
infrastructure.  Tested on ia64 and i386.

Enable interrupts while waiting for a disabled spinlock, but only if
interrupts were enabled before issuing spin_lock_irqsave().

This patch consists of three sections :-

* An architecture independent change to call _raw_spin_lock_flags()
  instead of _raw_spin_lock() when the flags are available.

* An ia64 specific change to implement _raw_spin_lock_flags() and to
  define _raw_spin_lock(lock) as _raw_spin_lock_flags(lock, 0) for the
  ASM_SUPPORTED case.

* Patches for all other architectures and for ia64 with !ASM_SUPPORTED
  to map _raw_spin_lock_flags(lock, flags) to _raw_spin_lock(lock).
  Architecture maintainers can define _raw_spin_lock_flags() to do
  something useful if they want to enable interrupts while waiting for
  a disabled spinlock.

This patch updates two error messages to reflect changes in the code.

From: "Theodore Ts'o" <tytso@mit.edu>

This patch versus improves the output produced by "echo 1 >
/proc/sys/vm/block_dump", in the following ways:

1) The messages are printed with KERN_DEBUG, so that even if sysklogd is
   running, if configured appropriately, it will not need to write to log
   files.

2) The inode which is dirtied by a process is now identified more
   precisely by inode number and filesystem ID, and by a dcache name if
   present.

3) In the generic filesystem sget function, the superblock id (s_id) is
   filled in with the filesystem type by default.  Filesystems which are
   block-device based will override s_id, but this allows pseudo
   filesystems such as tmpfs, procfs, etc.  to be identified in (2).

find_user() is being called from set/get_priority(), but it doesn't take the
needed lock, and those callers were forgetting to drop the refcount which
find_user() took.

This patch from Micha Feigin fixes some bugs in the earlier reiserfs 
commit default patch. The changelog:

* If you remounted without any commit=NNN option, it would assume commit=0
  and restore the defaults.  This patch makes it leave the current state alone
  if you don't pass commit=NNN.

* Added range check for cast from unsigned long to unsigned int.

Fix the 3c905C 10/100 transceiver initialisation woes.

Currently, shrink_slab() will decide that it needs to scan a certain number of
dentries, will call shrink_dcache_memory() requesting that this be done, and
shrink_dcache_memory() will simply bale out without doing anything because the
caller did not have __GFP_FS.

This has the potential to disrupt our lovely pagecache-vs-slab balancing act. 
So change things so that shrinker callouts can return -1, indicating that they
baled out.  This way, shrink_slab can remember that this slab was owed a
certain number of scannings and these will be correctly performed next time a
__GFP_FS caller comes by.

From: Andi Kleen <ak@suse.de>

We still need some kind of early CPU detection, e.g.  for the AMD768
workaround and for the slab allocator to size its slabs correctly for the
cache line.  Also some other code already had private early CPU routines.

This patch takes a new approach compared to the previous patch which caused
Andrew so much grief.  It only fills in a few selected fields in
boot_cpu_data (only the data needed to identify the CPU type and the cache
alignment).  In particular the feature masks are not filled in, and the
other fields are also not touched to prevent unwanted side effects.

Also convert the ppro workaround to use standard cpu data now. 

I'm not sure if slab still has the necessary support to use the cache line
size early; previously Manfred showed some serious memory saving with this
for kernels that are compiled for a bigger cache line size than the CPU (is
often the case on distribution kernels).  This code could be reenable now
with this patch.

From: "Protasevich, Natalie" <Natalie.Protasevich@UNISYS.com>

The patch fixes a problem with ES7000 Server Management mechanism that uses
platform register mip_port.  It was not initialized, so the mechanism was not
functional.

The patch also fixes the APIC destination for hierarchical and flat cluster
models used in ES7000.  The destination ID's reflect policies for Cascade
based systems which use logical delivery and lowest priority mechanism, and
for xAPIC based models that use physical delivery and fixed APIC destinations.

The patch also turns on NO_IOAPIC_CHECK (1) to avoid error messages and
attempts to re-write the ID, because on ES7000 all ID's are hard coded in the
BIOS and cannot be altered.

sys32_nfsservctl is the largest remaining syscall emulation handler that can
be consolidated.  mips and ia64 currently don't use this at all, parisc has a
simpler implementation than the one used by s390, sparc ppc and that the new
compat_sys_nfsservctl is based on.

The user access checks in the code are inconsistant at least, which should be
fixed here.

Compile tested only due to lack of proper test setup.

sys32_select has seven mostly but not exactly identical versions, so
consolidate them as compat_sys_select.  Based on the ppc64 implementation,
which most closely resembles sys_select.  One bug that was not caught by LTP

The code for sys32_execve/do_execve32 in most of the seven versions was copied
from fs/exec.c but not kept up-to-date.  The new compat_do_execve() function
is based on the mips code and has been resync'ed with do_execve().  IA64
changes are from Arun Sharma.

From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch changes the SELinux module to try to reset any descriptors it
closes on exec (due to a lack of permission by the new domain to the inherited
open file) to refer to the null device.  This counters the problem of SELinux
inducing program misbehavior, particularly due to having descriptors 0-2
closed when the new domain is not allowed access to the caller's tty.  This is
primarily to address the case where the caller is trusted with respect to the
new domain, as the untrusted caller case is already handled via AT_SECURE and
glibc secure mode.  The code is partly based on the OpenWall LSM, which in
turn drew from the OpenWall kernel patch.  Note that the code does not
guarantee that the descriptor is always re-opened to /dev/null; it merely
makes a reasonable effort to do so, but can fail under various conditions.

From: Andreas Dilger <adilger@clusterfs.com>

a) we don't call ext3_error() for an IO error in ext3_find_entry(), so we
   won't do the normal ext3 error handling (mark SB in error, remount-ro
   or panic if desired);
b) in empty_dir() we don't continue checking for non-empty blocks after a
   content error (ext3_check_dir_entry() calls ext3_error() already);
c) we had decided not to mark the SB in error for holes in directories to
   allow leway in the indexed-directory implementation, but this change
   incorrectly also disabled marking the SB in error for real IO errors.
