workaround for Big Sur and Bull systems

This should help some laptops where the generic PCI
code might otherwise believe that this range is unused.
The ACPI IO range is usually not visible as a standard
BAR.

Various people hit this in earlier kernels. The x86-64 kernel did not compile 
without CONFIG_IOMMU_GART in various configurations. Just add the missing symbol 
and export it. Also export iommu_merge while I am at it.

This fixes a bug in the new machine check handler on x86-64.

One nasty part was that when you got an MCE during boot up
then it would not always print it on the screen, but still
panic because it attempted to kill the idle task.

This patch does:
 - Always use KERN_EMERG when printing MCEs
 - Always panic and print on screen before killing idle loop
   or init.

Documentation for the Sharp-LH machines.

Patch from Marc Singer

Include files for this updated lh7a40x patch set.  The changes in this
set from the previous are mostly cosmetic.  The memory macros were
reworked in order to be more similar to the other ARM versions.  The
previous versions produced the same results, but the forms are
slightly different.

Patch from Marc Singer

Updated change set for the 2.6.5 kernel *and* for the April 8th arm
patch.  Also included are changes suggested by Russell that merge
several of the files in the mach- directory.  I have also endeavored
to remove all unnecessary whitespace additions.

Note that since I've found the cause of an annoying user-space crash,
I believe that this patch is OK.  The crash appears to have nothing to
do with the system setup.

Patch from Tony Lindgren

This patch syncs the mainline kernel with the linux-omap tree. The
patch contains following updates:
- Move virtual IO area to 0xfefb0000 from 0xfffb0000 to fix parts of
  IO area  overlapping with ARM Linux reserved memory area
- Add support to OMAP-730, OMAP-5912, and OMAP-1710 processors
- Reorganize board support
- Add OMAP core detection
This patch requires ARM Linux patch 1844/1 be applied to compile
OMAP-730 and OMAP-5912

   On IDI module cleanup, the freed card must be removed from list.  
   Use list_empty() instead of list_for_each() loop. Thanks Linus.

We don't bother aligining them on a cacheline boundary, since
that is totally excessive in some configurations (especially
P4's with 128-byte cachelines).

Instead, we make the minimum inline string size a bit longer,
and re-order a few fields that allow for better packing on
64-bit architectures, for better memory utilization.

I moved this a little too late - we need to run populate_rootfs() before
running initcalls because some driver initcalls need to open files for
firmware.

The populate_rootfs() call is still coming after init_idle(), so it won't
knock the scheduler over.

This is a version of Binary Increase Control (BIC) TCP
developed by NCSU.   It is yet another TCP congestion control
algorithm for handling big fat pipes. For normal size congestion
windows it behaves the same as existing TCP Reno, but when window
is large it uses additive increase to ensure fairness and when
window is small it uses binary search increase.

For more details see the BIC TCP web page
 http://www.csc.ncsu.edu/faculty/rhee/export/bitcp/

The original code was for web100 (2.4); this version is pretty
much the same but targeted for 2.6 with less sysctl parameters 
and more constants.

I don't have a real high speed long haul network to test, but
when running over 1G links with delays, the performance is more stable
(ie tests are repeatable) and as fast as existing Reno.

Avoid the use of sizeof() and pointer arithmetic to get to the end
of sctp_cookie structure. Instead use the last element peer_init which
is a zero-sized array as the offset.

The purpose of this is to allow sockets created by the kernel in this way
to be passed through the LSM socket creation hooks and be labeled and
mediated in the same manner as other sockets.

This patches addresses a class of potential issues with LSMs, where such
sockets will not be labeled correctly (if at all), or mediated during
creation.  Under SELinux, it fixes a specific bug where RPC sockets
created by the kernel during TCP NFS serving are unlabeled.

Under SELinux, and potentially other LSMs, we need to be able to
distinguish between user sockets and kernel sockets.  For SELinux
specifically, kernel sockets need to be specially labeled during creation,
then bypass access control checks (they are controlled by the kernel
itself and not subject to SELinux mediation).

This addresses a class of potential issues in SELinux where, for example, 
a TCP NFS session times out, then the kernel re-establishes an RPC 
connection upon further user activity.  We do not want such kernel 
created sockets to be labeled with user security contexts.

sock_create() and sock_create_kern() are wrapper functions, which seems 
semantically clearer to me than e.g. adding a flag to sock_create().  If 
you prefer the latter, then let me know.

The patch also adds an argument to the LSM socket creation functions
indicating whether the socket being created is a kernel socket or not.

This one is a little funny.  The SGI trees don't show this issue because dmapi
and quota are separate modules so they must be unloaded before xfs_fs_exit can
be called at all.

So let's move the exitcalls for them in mainline first to simulate that
behaviour.

From: Paul Mackerras <paulus@samba.org>

This patch fixes a bug in the pmac-zilog driver where if you enable
CRTSCTS mode, it won't output data when CTS is asserted.  On
powermacs, the CTS input is inverted.  It also fixes a logic bug in
testing for CTS and DCD changes.

   Check for last adapter link is done by next member,
   because entries are not removed yet.

They all have 128 bytes of ACPI/TCO IO space pointed to
by config space register 0x40, and 64 bytes of GPIO space
pointed to by 0x58.

Thanks to Jun Nakajima for the full list.
