Optimize first/node_node

Optimize nodemask_t slightly.  The x86-64 find_first/next_bit uses
__builtin_constant_p on the size argument to special cases small single
long word searches.  But most gccs don't make __builtin_constant_p true
when an argument is passed through an inline function.  Move the constant
into the inline function to avoid this.  This generates a lot better code
for node searches on x86-64.

On some systems, the first PCI bus has a ISA I/O hole at the first 16MB.
We can't use this space for DMA addresses on the bus.

On Python-based machines, we'll skip the first 256MB on buses that have the
hole, just as we do on later systems.  This means that the first bus will
have 768MB of DMA space shared between the devices on it.

When the iseries_veth driver module is unloaded there is the potential for an
oops and also some memory leakage.

Because the HvLpEvent_unregisterHandler() function did no synchronisation,
it was possible for the handler that was being unregistered to be running
on another CPU *after* HvLpEvent_unregisterHandler() had returned.  This
could cause the iseries_veth driver to leave work in the events work queue
after the module had been unloaded.  When that work was eventually executed
we got an oops.

In addition some of the data structures in the iseries_veth driver were not
being correctly freed when the module was unloaded.

This is the second patch, we make iseries_veth call flush_scheduled_work()
after we are sure the handler is no longer running, and also fix the memory
leaks.

I just discovered there's a thinko in the mark-page-accessed change in
do_generic_mapping_read() in 2.6.11-rc1.  ra.prev_page is compared to index
to see if we read from this page before - except that prev_page is actually
set to the recent page or even a page in front of the current page.

So we should store ra.prev_page in a seperate variable at the start of
do_generic_mapping_read().
