This patch slightly change the TLB flush batch mecanism so that we
store the full vaddr (including vsid) when adding an entry to the
batch so that the flush part doesn't have to get to the context.
This cleans it a bit, and paves the way to future updates like
dynamic vsids.

Replace some of the hard-coded constants with PAGE_SIZE/SHIFT/ORDER where
appropriate.
Likewise, in a couple of places it doesn't make sense to base some
allocations on page size when all that's required is a constant 4K,

There are potential cases in the future where the IOMMU might be
mapping smaller pages than the regular MMU is using. Keep the
allocator working on MMU pagesizes, but the low-level mapping
functions need to map more than one TCE entry per page to deal with
this.

Split out the implementation-specific parts of include/asm-ppc64/iommu.h
to separate include files (tce.h and dart.h respectively).
The generic iommu code really doesn't care about the underlying
implementation, and the TCE and DART stuff is completely different.

Merged ppc_asm.h between ppc32 & ppc64. The majority of the file is

Kill an unused member of the i2c_adapter structure. This additionally
fixes a potential bug, because <linux/i2c.h> doesn't include
<linux/config.h>, so different files including <linux/i2c.h> could see a
different definition of the i2c_adapter structure, depending on them
including <linux/config.h> (or other header files themselves including
<linux/config.h>) before <linux/i2c.h>, or not.

Added ppc_sys device and system definitions for PowerQUICC I devices. This
will allow drivers for PQI to be proper platform device drivers. Currently
sys section contains only MPC885 and MPC866. Identification should be done
with identify_ppc_sys_by_name call, with board-specific "name" string
passed, since PQI do not have any register that could identify the SOC.

This patch implements a stack trace for a thread, not unlike sysrq-t does.
The advantage to this is that a break point can be placed on showreqs, so that
upon showing the stack, you jump immediately into the debugger. While sysrq-t
does the same thing, sysrq-t shows *all* threads stacks. It also doesn't work
right now. In the future, I thought it might be acceptable to make this show
all pids stacks, but perhaps leaving well enough alone and just using sysrq-t
would be okay. For now, upon receiving the stack command, UML switches
context to that thread, dumps its registers, and then switches context back to
the original thread. Since UML compacts all threads into one of 4 host
threads, this sort of mechanism could be expanded in the future to include
other debugging helpers that sysrq does not cover.
Note by jdike - The main benefit to this is that it brings an arbitrary thread
back into context, where it can be examined by gdb. The fact that it dumps it
stack is secondary. This provides the capability to examine a sleeping
thread, which has existed in tt mode, but not in skas mode until now.
Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly
anyway.

As discussed in the dccp@vger mailing list:
Now applications have to use setsockopt(DCCP_SOCKOPT_SERVICE, service[s]),
prior to calling listen() and connect().
An array of unsigned ints can be passed meaning that the listening sock accepts
connection requests for several services.
With this we can ditch struct sockaddr_dccp and use only sockaddr_in (and
sockaddr_in6 in the future).

Thomas Gleixner reported that mmaping and unmapping each physical
page in turn eventually caused the kernel to oops. It appears
that pfn_valid() in the discontigmem case was too simplistic for
proper operation.
Tighten the logic so we also check if the PFN is within the range
of the selected memory node.

Patch from Lennert Buytenhek
This patch:
- changes the ixp2000_reg_write accessor to take a 'volatile void *'
instead of a 'volatile unsigned long *', which then allows passing in
a u32 * as first argument without being greeted with a warning; and
- adds an ixp2000_reg_read accessor.
We can then use these accessors in ixp2000 code to access on-chip
peripherals, instead of directly dereferencing pointers. This is for
use by the ixp2000 microengine driver which was recently announced on
netdev. We can't use readl/writel on the ixp2000 since it is usually
run in big-endian mode, and on big-endian platforms, readl/writel
perform byteswapping.
A future patch will remove the readback from ixp2000_reg_write, since
it's not needed to prevent erratum #66, and add manual readbacks to the
places that need them (writes are not synchronous since we map in device
space using XCB=101 nowadays), such as interrupt disabling and GPIO
manipulation. See also:

ip_vs_ftp when loaded can create NAT connections with unknown client
port for passive FTP. For such expectations we lookup with cport=0 on
incoming packet but it matches the format of the persistence templates
causing packets to other persistent virtual servers to be forwarded to
real server without creating connection. Later the reply packets are
treated as foreign and not SNAT-ed.
This patch changes the connection lookup for packets from clients:
* introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the
connection as template
* create new connection lookup function just for templates -
ip_vs_ct_in_get
* make sure ip_vs_conn_in_get hits only connections with
IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way
we avoid returning template when looking for cport=0 (ftp)

[ALSA] Remove superfluous PCI ID definitions
broke the RME32 and RME96 drivers, since the PCI IDs they use seem to have
changed names. Here's a patch to fix this -- compile tested only, since I
have no idea what the hardware even is.
Fix the build of the RME32 and RME96 drivers by having them use the
PCI_DEVICE_ID_RME_xxx names defined in <linux/pci_ids.h> instead of the
PCI_DEVICE_ID_xxx names that they used to define themselves.
Also fix the typo in the id PCI_DEVICE_IDRME__DIGI96_8_PAD_OR_PST so the
name is PCI_DEVICE_ID_RME_DIGI96_8_PAD_OR_PST.

Adds all defines, ioctls and structs needed for the sliced VBI API
VBI = Vertical Blank Interval.
It is related with the way TV signals work. It sends a line, then, it has a
retrace time to allow the tube to move electrons to the beginning of the next
line. This was the main reason at the beginning of analog B&W TV.
There is a lot of bandwidth lost on VBI. So, lots of TV systems use it to
send other information such as Closed Captions and Teletext. Also,
broadcasters uses this as a channel to exchange information from the content
producer to their subsidiaries at each city.
There's already a raw VBI interface on V4L2 api, used for Closed Captions and
Teletext. The decoding is doing at userlevel space and it is mostly for
analog TV signals, non encoded.
Encoded signals (MPEG, for example), may need also to transmit other
information (like, for example, display aspect, i.e. 4x3, widescreen...).
Sliced VBI interface is a method to allow the video stream to transmit this
kind of information.

Akita Support
Add the platform support code for two new Sharp Zaurus Models, Spitz

This patch also adds most of the foundations for Akita (SL-C1000) Support.
