After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

AUTH_UNIX authentication (the standard with NFS) has a limit of 16 groups ids.
 This causes problems for people in more than 16 groups.

So allow the server to map a uid into a list of group ids based on local
knowledge rather depending on the (possibly truncated) list from the client.

If there is no process on the server responding to upcalls, the gidlist in the
request will still be used.

Add support for using a filesystem UUID to identify and export point in the
filehandle.

For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room.  For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.

When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.

If we are using the same version/fsid as a current filehandle, then there is
no need to verify the the numbers are valid for this export, and they must be
(we used them to find this export).

This allows us to simplify the fsid selection code.

Also change "ref_fh_version" and "ref_fh_fsid_type" to "version" and
"fsid_type", as the important thing isn't that they are the version/type of
the reference filehandle, but they are the chosen type for the new filehandle.

Most files in the 'nfsd' filesystem are transactional.  When you write, a
reply is generated that can be read back only on the same 'file'.

If the reply has zero length, the 'write' will incorrectly return a value of
'0' instead of the length that was written.  This causes 'rpc.nfsd' to give an
annoying warning.

This patch fixes the test.

Since serial devices are powered down when not in use and some of those

The patch below works around a minor bug found in the UART of the remote
management card used in many HP ia64 and parisc servers (aka the Diva
UARTs).  The problem is that the UART does not reassert the THRE interrupt
if it has been previously cleared and the IIR THRI bit is re-enabled.  This
can produce a very annoying failure mode when used as a serial console,
allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it
into working again (ie.  an unattended reboot could stall).

To solve this problem, a backup timer is introduced that runs alongside the
standard interrupt driven mechanism.  This timer wakes up periodically,
checks for a hang condition and gets characters moving again.  This backup
mechanism is only enabled if the UART is detected as having this problem,
so systems without these UARTs will have no additional overhead.

This version of the patch incorporates previous comments from Pavel and
removes races in the bug detection code.  The test is now done before the
irq linking to prevent races with interrupt handler clearing the THRE
interrupt.  Short delays and syncs are also added to ensure the device is
able to update register state before the result is tested.

Aristeu says:

  this was tested on the following HP machines and solved the problem:
  rx2600, rx2620, rx1600 and rx1620s.

hpa says:

  I have seen this same bug in soft UART IP from "a major vendor."

On ia64, drivers/base/dma-mapping.c doesn't build because it calls
dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be
terminally broken; the calls end up generating errors like

    drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release':
    drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent'

because the multiple levels of macro expansion in <asm/dma-mapping.h> and
<asm/machvec.h> end up turning a call to dma_free_noncoherent() into
ia64_mv.platform_dma_free_coherent (instead of the intended
ia64_mv.dma_free_coherent).

This patch fixes this by converting dma_{alloc,free}_noncoherent() into
inline functions that call the corresponding coherent functions, instead of
trying to do this with macros.

udbg_early_init() is a function used on 64 bit systems, which
initializes whichever early udbg backend is configured.  This function
is not called on 32-bit, however if btext early debug is enabled it
does have an explicit, inline, #ifdef-ed assignment performing
analagous initialization.

This patch makes things more uniform by folding the btext
initialization as an option into udbg_early_init() and calling that
from the 32-bit setup path.

This can be used for serial ports that are connected to an

serial support.
It will automatically take over devices that come from the
legacy serial detection, which usually is only one device.

In some cases, rtas may be set up to use the serial port
in the firmware, which allows easier debugging before probing
the serial ports. In this case, the "used-by-rtas" property
must be set by the firmware. This patch also adds code to the
