RDMA/amso1100: Fix build with debugging off

Since pr_debug() has changed from a macro to an inline function when
DEBUG is not defined, its arguments now need to be defined even when
debugging is off.  Therefore to_event_str() and to_qp_state_str() need
to be moved out of #ifdef DEBUG.  The compiler will throw the
definitions away if DEBUG is not defined, but it needs to be able to
see that the functions exist.

IB/cm: Send DREP in response to unmatched DREQ

Currently a DREP is only sent in response to a DREQ if a connection
has been found matching the DREQ, and it is in the proper state.  Once
a DREP is sent, the local connection moves into timewait.  Duplicate
DREQs received while in this state result in re-sending the DREP.

However, it's likely that the local connection will enter and exit
timewait before the remote side times out a lost DREP and resends a DREQ.
To handle this, we send a DREP in response to a DREQ, even if a local
connection is not found.  This avoids maintaining disconnected
id's in timewait states for excessively long times, just to handle a
lost DREP.

IB/cm: Fix timewait crash after module unload

If the ib_cm module is unloaded while id's are still in timewait, the

id's exit timewait, their timers will fire, leading to a crash trying
to access the destroyed work queue.

We need to track id's that are in timewait, and cancel their deferred

IB/srp: Enable multiple connections to the same target

Enable multiple concurrent connections to the same SRP target:

1) Use port GUID instead of node GUID in the initiator port
   identifier.  This allows connections to be made from multiple HCA
   ports at the same time.
2) Let the user specify the identifier extention when adding the
   device.  This allows userspace to make multiple connections even
   from the same port, if it wants too.

Without this, only one connection can be made from any given HCA, even
if it has multiple ports, because we don't use multi-channel mode, so
targets will only allow one connection from a given initiator port ID.

[PATCH] x86_64 irq: Scream but don't die if we receive an unexpected irq

Due to code bugs or misbehaving hardware it is possible that we can
receive an interrupt that we have not mapped into a linux irq.  Calling
BUG when that happens is very rude, and if the problem is mild enough
prevents anything else from getting done.

So instead of calling BUG just scream loudly about the problem and
continue running.  We don't have enough knowledge to know which
interrupt triggered this behavior so we don't acknowledge it.  This will
likely prevent a recurrence of the problem by jamming up the works with
an unacknowledged interrupt.

If the interrupt was something important it is quite possible that
nothing productive will happen past this point.  But it is now at least
possible to keep working if the kernel can survive without the interrupt
we dropped on the floor.

Solutions like irqpoll should generally make dropped irqs non-fatal.

[PATCH] Introduce vfs_listxattr

This patch moves code out of fs/xattr.c:listxattr into a new function -
vfs_listxattr. The code for vfs_listxattr was originally submitted by Bill
Nottingham <notting@redhat.com> to Unionfs.

Sorry about that.  The reason for this submission is to make the
listxattr code in fs/xattr.c a little cleaner (as well as to clean up
some code in Unionfs.)

Currently, Unionfs has vfs_listxattr defined in its code.  I think
that's very ugly, and I'd like to see it (re)moved.  The logical place
to put it, is along side of all the other vfs_*xattr functions.

Overall, I think this patch is benefitial for both kernel.org kernel and
Unionfs.

Revert "[POWERPC] Don't get PCI IRQ from OF for devices with no IRQ"

This reverts commit 41550c5128150175197257b6ceab2cd50dea7b51.

Quoth Ben Herrenschmidt:
 "Please revert this one for now.  It seems to break G5s :( Looks like
  PCI cells inside Apple IO ASICs don't have a PCI_INTERRUPT_LINE set.

Commit ca4aa09635516258f158a7bc1594a794e4c34864 fixed waiting for the
structure to get initialised, but it is also possible to break out of
the loop while still in TASK_INTERRUPTIBLE.

Replace the whole thing by wait_event_interruptible, which is much more
readable, and doesn't suffer from these problems.

[PATCH] sparc32 rwlock fix

read_trylock() is broken on sparc32 (doesn't build and didn't work
right, actually).  Proposed fix:

 - make "writer holds lock" distinguishable from "reader tries to grab
   lock"

 - have __raw_read_trylock() try to acquire the mutex (in LSB of lock),
   terminating spin if we see that there's writer holding it.  Then do
   the rest as we do in read_lock().

[PATCH] x86_64 irq: Allocate a vector across all cpus for genapic_flat.

The problem we can't take advantage of lowest priority delivery mode if
the vectors are allocated for only one cpu at a time.  Nor can we work
around hardware that assumes lowest priority delivery mode is always
used with several cpus.

So this patch introduces the concept of a vector_allocation_domain.  A
set of cpus that will receive an irq on the same vector.  Currently the
code for implementing this is placed in the genapic structure so we can
vary this depending on how we are using the io_apics.

This allows us to restore the previous behaviour of genapic_flat without
removing the benefits of having separate vector allocation for large
machines.

This should also fix the problem report where a hyperthreaded cpu was
receving the irq on the wrong hyperthread when in logical delivery mode
because the previous behaviour is restored.

This patch properly records our allocation of the first 16 irqs to the
first 16 available vectors on all cpus.  This should be fine but it may
run into problems with multiple interrupts at the same interrupt level.
Except for some badly maintained comments in the code and the behaviour
of the interrupt allocator I have no real understanding of that problem.
