Added prerequisite FORCE in several rules, now kbuild build a kernel even
the second time you try.
Corrected several errors to avoid errornous rebuild of targets in arch/arm
Lot's of trivial clean-up

DOH!!! Somebody clone me a replacement brain: I must have burnt
another fuse.  It turns out the new readpages was evading our
read/write serialization.

This broke things like 'ld' over NFS, which rewrites chunks of
files it has already written.

last direct call into fs code is gone

Sufficient locking for fifo_open is provided by the inode semaphore.

- fix loading of another configuration
- accept longer strings in configuration
- move conf_filename to mconf.c (it's the only user)
- fix off by one error during string scanning

I enhanced the sendfile method so that we could pass a proper actor to
it (which exposes the full power of the internal implementation).

Now knfsd calls the sendfile vector rather than depending on a
readpage() that hasn't been set up fully.

Sorry, one small goof...

Use new "nmi_enter/exit()" which acts the same as the regular irq
entries (increases the preempt count appropriately), but doesn't try to
start processing softirqs on nmi exit (it just decreases the count).

Given the previous set of patches that integrate NFS with the VM +
pdflush memory control, and add mechanisms to cope with low memory
conditions, the time is now ripe to rip out the 256 outstanding
request limit, as well as the associated LRU list in the superblock,
and the nfs_flushd daemon.

The following patch offers a 30% speed increase on my test setup with
512MB of core memory (iozone using 4 threads each writing a 512MB file
over 100Mbit to a Solaris server). Setting mem=64m, I still see a 2-3%
speed increase.

In order to better cope with low memory conditions, add slabs for
struct rpc_task and 'small' RPC buffers of <= 2k. Protect these using
mempools.

The only case where we appear to use buffers of > 2k is when
symlinking, and is due to the fact that the path can be up to 4k in
length. For the moment, we just use kmalloc(), but it may be worth it
some time in the near future to convert nfs_symlink() to use pages.

Tiny cleanups in IDE...

This removes two drivers from drivers/macintosh.  The files affected are
all in drivers/macintosh.  First, the patch removes the old macintosh
ADB keyboard driver and the macintosh keymap file, which are no longer
used now that we use the input layer and the adbhid.c driver.  Secondly,
it removes the drivers/macintosh/rtc.c driver, which was only ever used
on PPC, and which is obsolete now that we use the drivers/char/genrtc.c
driver instead.

This updates the ADB driver and the three low-level ADB bus adaptor
drivers used on powermacs.  The files affected are all in
drivers/macintosh; they are adb.c, macio-adb.c, via-cuda.c and
via-pmu.c.

The main changes in this patch are:

- Remove the use of global cli/sti and replace them with local cli/sti,
  spinlocks and semaphores as appropriate.
- Use DECLARE_WORK/schedule_work instead of tq_struct/schedule_task.
- Improvements to the PMU interrupt handling and sleep/wakeup code.

clean up RPC client's RTO estimator.

the new RPC RTO estimator has some jiffies wrap problems.

fix up the last remaining static struct initializers in the RPC client and
portmapper.

TCP connect semantics now assume the rpciod is already running, so there
is no longer a need to bump the rpciod semaphor when connecting or closing
an RPC over TCP transport socket.

smaller patch that removes unused RPC cruft.

remove some definitions and declarations that are no longer used.

The RPC clnt struct has a cl_flags field with one bit defined (in an NFS
header, no less).  no one ever sets the flag, so remove flag, field, and
test in NFSv2 XDR routines that check for the flag.
