[POWERPC] Fix Maple secondary IDE interrupt

The IDE driver will pick up the PCI IRQ for both channels on Maple
despite the fact that it's in legacy mode. This works around it by
"hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured
in legacy mode on the Maple platform, thus causing the driver to call
pci_get_legacy_ide_irq() which will return the correct interrupts for
both channels.

[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.

[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.

ieee1394: nodemgr: fix startup of knodemgrd

Revert a thinko in commit d2f119fe319528da8c76a1107459d6f478cbf28c:
When knodemgrd starts, it needs to sleep until host->generation was
incremented above its initial value of 0.  My wrong logic caused it to
start sending requests when the bus wasn't completely ready.  Seen as
"AT dma reset ctx=0, aborting transmission" messages in 2.6.19-rc1.

[PATCH] m68k pt_regs fixes

m68k_handle_int() split in two functions: __m68k_handle_int() takes
pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
*.

Places where we used to call m68k_handle_int() recursively with the same
pt_regs have simply lost the second argument, the rest is switched to
__m68k_handle_int().

The rest of patch is just dropping pt_regs * where needed.
