FUTEX_REQUEUE operation has been added to the kernel mainly to improve
pthread_cond_broadcast which previously used FUTEX_WAKE INT_MAX op.
pthread_cond_broadcast releases internal condvar mutex before FUTEX_REQUEUE
operation, as otherwise the woken up thread most likely immediately sleeps
again on the internal condvar mutex until the broadcasting thread releases it.

Unfortunately this is racy and causes e.g.
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/nptl/tst-cond16.c?rev=1.1&content-type=text/x-cvsweb-markup&cvsroot=glibc
to hang on SMP.

http://listman.redhat.com/archives/phil-list/2004-May/msg00023.html contains
analysis how the hang happens, the problem is if any thread does
pthread_cond_*wait in between releasing of the internal condvar mutex and
FUTEX_REQUEUE operation, a wrong thread might be awaken (and immediately go to
sleep again because it doesn't satisfy conditions for returning from
pthread_cond_*wait) while the right thread requeued on the associated mutex
and there would be nobody to wake that thread up.

The patch below extends FUTEX_REQUEUE operation with something FUTEX_WAIT
already uses:

FUTEX_CMP_REQUEUE is passed an additional argument which is the expected value
of *futex.  Kernel then while holding the futex locks checks if *futex !=
expected and returns -EAGAIN in that case, while if it is equal, continues
with a normal FUTEX_REQUEUE operation.  If the syscall returns -EAGAIN, NPTL
can fall back to FUTEX_WAKE INT_MAX operation which doesn't have this problem,
but is less efficient, while in the likely case that nobody hit the (small)
window the efficient FUTEX_REQUEUE operation is used.

Currently the iSeries virtual ethernet driver has no Tx watchdog timer. 
This makes it vulnerable to clagging up if the other end of connection is
misbehaving - in particular if it is not giving timely hypervisor level
acks to our data frams.

This patch adds a watchdog timer which resets the connection to any lpar we
seem to be having trouble sending to.  With any luck the other end might
behave better after the reset.  If not, this will at least unclag the queue
for a while so we can keep talking to the lpars which are behaving
correctly.

This fixes a couple of bugs in arch/ppc64/kernel/prom.c.  We were
missing a couple of places where we needed to use RELOC().  I added the
RELOC in one case, and in the other, moved the variable that we were
accessing onto the stack (and reduced its size).  (We use the variable
to get a property value, but we aren't interested in the value, just in
whether the property exists or not.  Since we pass the size of the
variable to the OF getprop call, it won't overflow.) The effect of
missing the RELOCs would be that random memory locations get used on IBM
pSeries systems (possibly causing random boot failures). 

The other thing that this does is add a linux,phandle property to each
node, containing the phandle for the node, which is the token that OF
uses to identify the node.  Some nodes reference other nodes by means
of their phandle.  Without the linux,phandle property, userspace code
looking at the OF device-tree image in /proc/device-tree has no way of
knowing which other node is being referenced.

This fixes compilation of x86-64 without CONFIG_NUMA again (got broken
by the previous patchkit)

Older versions of gcc were unhappy with our previous trick, and
just separating out the __CHECKER__ case made it much simpler.

On i386, stack usually grows with "sub $0x8,%esp" and shrinks with
"add $0x8,%esp" respectively.  In some cases, though, stack grows with
"add $0xffffff80,%esp" and shrinks with "sub $0xffffff80,%esp".
Obviously, we don't want to miss those cases.

Since in either case add and sub seem to be balanced and contain the
same parameter, we don't need a second regex.  We simply accept hex
numbers of up to 8 digits and treat them as negative numbers when the
sub appears to be a little too high.

...or so I thought.  But another day of testing proved me wrong again.

Some functions do stuff like "sub $0x10,%esp", ..., "add $0x20,%esp".
In other words, add and sub are *NOT* balanced.  Manual inspection
showed that 0x20 is a more realistic number, so I accept either
variant, just in case.  We pay for this with a bunch of duplicates in
our output, but that beats missing some stack hogs.

In the long run, this script has to be replaced by gcc options,
really.  Looking at the result and guessing back is such a stupid
idea.
