Benjamin Herrenschmidt [Thu, 20 Dec 2007 04:28:08 +0000 (15:28 +1100)]
PCI: Add pci_enable_device_{io,mem} intefaces

The pci_enable_device_bars() interface isn't well suited to PCI
because you can't actually enable/disable BARs individually on
a device. So for example, if a device has 2 memory BARs 0 and 1,
and one of them (let's say 1) has not been successfully allocated
by the firmware or the kernel, then enabling memory decoding
shouldn't be permitted for the entire device since it will decode
whatever random address is still in that BAR 1.

So a device must be either fully enabled for IO, for Memory, or
for both. Not on a per-BAR basis.

This provides two new functions, pci_enable_device_io() and
pci_enable_device_mem() to replace pci_enable_device_bars(). The
implementation internally builds a BAR mask in order to be able
to use existing arch infrastructure.

PCI: export pci_restore_msi_state()

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.

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.
