This allows us to allocate resources to hotplug bridges during
remove/rescan.

We need to move the function to setup-bus.c so it can use
__pci_bus_size_bridges and __pci_bus_assign_resources directly to take
the add_list resource tracking list.

Current rescan will not touch bridge MMIO and IO.

Try to reuse pci_assign_unassigned_bridge_resources(bridge) to update bridge
resources, if child devices need more resources.

Only do that for bridges whose children are all removed already; i.e. don't
release resources that could already be in use by drivers on child devices.

We found reassignment can not find a range for one resource, even if the
total available range is large enough.

bridge b1:02.0 will need 2M+3M
bridge b1:03.0 will need 2M+3M

so bridge b0:00.0 will get assigned: 4M : [f8000000-f83fffff]
   later is reassigned to 10M : [f8000000-f9ffffff]

b1:02.0 is assigned to 2M : [f8000000-f81fffff]
b1:03.0 is assigned to 2M : [f8200000-f83fffff]

After that b1:03.0 get chance to be reassigned to [f8200000-f86fffff],
but b1:02.0 will not have chance to expand, because b1:03.0 is using in
middle one.

Thus b2:00.0 BAR 9 does not get assigned...

root cause:
b1:02.0 can not be added more range, because b1:03.0 is just after it;
no space between the required ranges.

Solution:
Try to assign required + optional all together at first, and if that
fails, try again with just the required resources.

During debug of one SRIOV enabled hotplug device, we found found that
add_size is not passed properly.

The device has devices under two level bridges:

 |           +-01.0-[90-9f]--
 |           +-02.0-[a0-af]----00.0-[a1-a3]--+-02.0-[a2]--+-00.0  Oracle Corporation Device
 |           |                               \-03.0-[a3]--+-00.0  Oracle Corporation Device

Which means later the parent bridge will not try to add a big enough range:

It turns out we did not calculate size1 properly.

static resource_size_t calculate_memsize(resource_size_t size,
                resource_size_t min_size,
                resource_size_t size1,
                resource_size_t old_size,
                resource_size_t align)
{
        if (size < min_size)
                size = min_size;
        if (old_size == 1 )
                old_size = 0;
        if (size < old_size)
                size = old_size;
        size = ALIGN(size + size1, align);
        return size;
}

We should not pass add_size with min_size in calculate_memsize since
that will make add_size not contribute final add_size.

So just pass add_size with size1 to calculate_memsize().

With this change, we should have chance to remove extra addon in
pci_reassign_resource.

The use case of this is when a driver wants to call FLR when a device
is attached to it using the SysFS "bind" or "unbind" functionality.

The call chain when a user does "bind" looks as so:

 echo "0000:01.07.0" > /sys/bus/pci/drivers/XXXX/bind

and ends up calling:
  driver_bind:
    device_lock(dev);  <=== TAKES LOCK
    XXXX_probe:
         .. pci_enable_device()
         ...__pci_reset_function(), which calls

The __pci_reset_function_locked function allows the the drivers

pci_revert_fw_address() is used to reinstate a PCI device's original
FW-assigned BIOS BAR value(s) if normal resource assignment fails.

When attempting to reinstate an address, the point within the resource
tree from which to attempt the new resource request should be the parent
resource corresponding to the device, not the base of the resource tree
(ioport_resource or iomem_resource).  For PCI devices this would
typically be the resource corresponding to the upstream PCI host bridge
or P2P bridge aperture.

This patch sets the point within the resource tree to attempt a new
resource assignment request to the PCI device's parent resource and only
if that fails does it fall back to the base ioport_resource or
iomem_resource.

|    PCI: Only call pci_stop_bus_device() one time for child devices at remove

The above changed the behavior of pci_remove_behind_bridge that
yenta_cardbus depended on.  So restore the old behavoir of
pci_remove_behind_bridge (which requires stopping and removing of all
devices) by:

1. rename pci_remove_behind_bridge to __pci_remove_behind_bridge, and let
   __pci_remove_bus_device() call it instead.
2. add pci_stop_behind_bridge that will stop devices behind a bridge
3. add back pci_remove_behind_bridge that will stop and remove devices
   under bridge.

For an SRIOV device, PCI_SRIOV_SYS_PGSIZE should be set before

so this change is required on powerpc box with 64k base page size.
    
This is a regression caused due to moving SRIOV init to sriov_enable().

In error cleanup of agp_backend_initialize() and in agp_backend_cleanup(),
agp_destroy_page() is passed virtual address of the scratch page. This
leads to a kernel warning if the initialization fails (or upon regular
cleanup) as pointer to struct page should be passed instead.

Both changes in dc97b340 cause serious
regressions in the nouveau driver.

move_notify() was originally able to presume that bo->mem is the old node,
and new_mem is the new node.  The above commit moves the call to
move_notify() to after move() has been done, which means that now, sometimes,
new_mem isn't the new node at all, bo->mem is, and new_mem points at a
stale, possibly-just-been-killed-by-move node.

This is clearly not a good situation.  This patch reverts this change, and
replaces it with a cleanup in the move() failure path instead.

The second issue is that the call to move_notify() from cleanup_memtype_use()
causes the TTM ghost objects to get passed into the driver.  This is clearly
bad as the driver knows nothing about these "fake" TTM BOs, and ends up
accessing uninitialised memory.

I worked around this in nouveau's move_notify() hook by ensuring the BO
destructor was nouveau's.  I don't particularly like this solution, and
would rather TTM never pass the driver these objects.  However, I don't
clearly understand the reason why we're calling move_notify() here anyway
and am happy to work around the problem in nouveau instead of breaking the
behaviour expected by other drivers.

My forcewake spinlock patches have a functional conflict with Ben
Widawsky's gen6 drpc support for debugfs. Result was a benign warning
about trying to read an non-atomic variabla with atomic_read.

Note that the entire check is racy anyway and purely informational.
Also update it to reflect the forcewake voodoo changes, the kernel can
now also hold onto a forcewake reference for longer times.

If GPU lockup is detected in ib_pool get we are holding the ib_pool
mutex that will be needed by the GPU reset code. As ib_pool code is
safe to be reentrant from GPU reset code we should not block if we
are trying to get the ib pool lock on the behalf of the same userspace
caller, thus use the radeon_mutex_lock helper.

If the master tries to authenticate a client using drm_authmagic and
that client has already closed its drm file descriptor,
either wilfully or because it was terminated, the
call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory
and corrupt it.

Typically this results in a hard system hang.

This patch fixes that problem by removing any authentication tokens
(struct drm_magic_entry) open for a file descriptor when that file
descriptor is closed.
