PCI: Fix bus resource assignment on 32 bits with 64b resources

The current pci_assign_unassigned_resources() code doesn't work properly
on 32 bits platforms with 64 bits resources. The main reason is the use
of unsigned long in various places instead of resource_size_t.

This is a pre-requisite for making powerpc use the generic code instead of
its own half-useful implementation.

PCI: Mem Policy: fix mempolicy usage in pci driver

In an attempt to ensure memory allocation from the local node, the pci
driver temporarily replaces the current task's memory policy with the
system default policy.  Trying to be a good citizen, the driver then call's
mpol_get() on the new policy.  When it's finished probing, it undoes the
'_get by calling mpol_free() [on the system default policy] and then
restores the current task's saved mempolicy.

A couple of issues here:

1) it's never necessary to set a task's mempolicy to the
   system default policy in order to get system default
   allocation behavior.  Simply set the current task's
   mempolicy to NULL and allocations will fall back to
   system default policy.

2) we should never [need to] call mpol_free() on the system
   default policy.  [I plan on trapping this with a VM_BUG_ON()
   in a subsequent patch.]

This patch removes the calls to mpol_get() and mpol_free()
and uses NULL for the temporary task mempolicy to effect
default allocation behavior.
