Now that nfsd uses a list of pages for requests instead of
one large buffer, NFSv4 need to know about this.

The most interesting part of this is that it is possible
that section of a request, like a path name, could span
two pages, so we need to be able to kmalloc as little bit
of space to copy them into, and make sure they get
freed later.

We don't implement the ancient stat syscalls on ppc64 since early libcs
wont run on ppc64 (they hardcode the incorrect cacheline size).

Here is the a pre-patch in the attempt to get rid of 'struct
nfs4_compound', and the associated horrible union in 'struct
nfs4_op'.

It splits out the fields that are meant to do buffer overflow checking
and iovec adjusting on the XDR received/sent data. It moves support
for that nto the dedicated structure 'xdr_stream', and the associated
functions 'xdr_reserve_space()', 'xdr_inline_decode()'.

The patch also expands out the all macros ENCODE_HEAD, ENCODE_TAIL,
ADJUST_ARGS and DECODE_HEAD, as well as most of the DECODE_TAILs.

linux/interrupt.h needs:
	asm/system.h: smb_mb()
	linux/linkage.h: asmlinkage/FASTCALL/etc.

This changes the return type of the verify and setpolicy functions from
void to int.  While doing this, I've changed the values for minimum and
maximum supported frequency to be per CPU, as UltraSPARC needs this.

Additionally, small cleanups in various drivers.

Traditional naming in pci/setup-xx code assumes that
pdev_*/pbus_* functions are private, everything visible
from outer world should be pci_*.

The most important changes are:
	- allocate buffers on open(), not module load;
	- correct some failed allocation paths;
	- use wait_event;
	- C99 structs inits;

The most important changes are:
	* add suspend/resume support to the sonypi driver (not
	  based on driverfs however) (Florian Lohoff);
	* add "Zoom" and "Thumbphrase" buttons (Francois Gurin);
	* add camera and lid events for C1XE (Kunihiko IMAI);
	* add a mask parameter letting the user choose what kind
	  of events he wants;
	* use ACPI ec_read/ec_write when available in order to
	  play nice when latest ACPI is enabled;
	* several source cleanups.

Today we return EINVAL for fcntl with a lock with negative length.
POSIX-2001 says that the lock covers start .. start+len-1 if len >= 0
and start+len .. start-1 if len < 0.

The i_dev field is deleted and the few uses are replaced by i_sb->s_dev.

There is a single side effect: a stat on a socket now sees a nonzero
st_dev.  There is nothing against that - FreeBSD has a nonzero value as
well - but there is at least one utility (fuser) that will need an
update.

This patch breaks up and removes fs/devices.c, moving functions to more
logical places.

  character device functions -> char_dev.c
  init_special_inode() -> inode.c
  kdevname() -> libfs.c (this should die, but that's another patch)
  bad_sock_fops -> socket.c

This fixes some more file system for the CURRENT_TIME change:
AFS, ADFS, and a harmless one in CIFS.

Somehow these changes got lost in the original patch kit.

The Stanford checker found an error in advansys.c, the driver
is accessing field 6 in an array[6].  Since this is the only
place where this field is accessed it should be safe to simply
remove this line.

We don't need to send an empty message to
set up remote address when sending tcp reply, so
we don't.  Also, as the data is empty, we don't
need to set_fs.

If an NFS request arrives in a linear skb,
we don't need to copy it, particularly if the
network card has already done the DUB checksum.

This patch only copies a request if it is
already non-linear.
