Earlier patches to split out the hardware init for PCIe hotplug resulted in
some one-time initializations being redone on every resume cycle.  Eg.
irq/polling initialization.

This patch splits the hardware init into two parts, and separates the
one-time initializations from those so that they only ever get done once,
as intended.

PCI error recovery usually involves the PCI adapter being reset.
If the device is using MSI, the reset will cause the MSI state
to be lost; the device driver needs to restore the MSI state.

The pci_restore_msi_state() routine is currently protected
by CONFIG_PM; remove this, and also export the symbol, so
that it can be used in a modle.

Add and changes a few sanity checks in dmar.c.

1.  The haw field in ACPI DMAR table in VT-d spec doesn't describe the
   range of haw.  But since DMA page size is 4KB in DMA remapping, haw
   should be at least 4KB.  The current VT-d code in dmar.c returns failure
   when haw==0.  This sanity check is not accurate and execution can pass
   when haw is less than one page size 4KB.  This patch changes the haw
   sanity check to validate if haw is less than 4KB.

2. Add dmar_rmrr_units verification.

3. Add parse_dmar_table() verification.

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.

It blindly copies everything in the io_context, including the lock.
