This patch fixes this problem that pciehp driver will sleep
unnecessarily long when waiting for command completion. With this
patch, modprobe pciehp driver becomes very faster as follows for
instance.

So let's mark it as __deprecated now, which also has the side effect 
that noone can later whine that removing it might break some shiny 
external modules.

Oh, and if anything starts complaining "But this adds some warnings to 
my kernel build!", he should either first fix the 200 kB (sic) of 
warnings I'm getting in 2.6.19-rc5-mm2 starting at MODPOST or go to hell.

This patch adds the following changes into generic PCI code especially
for PCI legacy I/O port free drivers.

     - Added new pci_request_selected_regions() and
       pci_release_selected_regions() for PCI legacy I/O port free
       drivers in order to request/release only the selected regions.

     - Added helper routine pci_select_bars() which makes proper mask
       of BARs from the specified resource type. This would be very
       helpful for users of pci_enable_device_bars().

For pci mem resource that size is bigger than 4G, the sz returned by
pc_size will be 0.
So that resource is skipped, and register contained hi address will be
treated as another 32bit resource. We need to use sz64 and pci_sz64 for
64 bit resource for clear logical.  Typical usages for this: Opteron
system with co-processor and the co-processor could take more than 4G
RAM as pre-fetchable mem resource.

Fix the key serial number collision avoidance code in key_alloc_serial().

This didn't use to be so much of a problem as the key serial numbers were
allocated from a simple incremental counter, and it would have to go through
two billion keys before it could possibly encounter a collision.  However, now
that random numbers are used instead, collisions are much more likely.

This is fixed by finding a hole in the rbtree where the next unused serial
number ought to be and using that by going almost back to the top of the
insertion routine and redoing the insertion with the new serial number rather
than trying to be clever and attempting to work out the insertion point
pointer directly.

This fixes kernel BZ #7727.
