PCI : ability to relocate assigned pci-resources
Currently pci-bridges are allocated enough resources to satisfy their immediate
requirements. Any additional resource-requests fail if additional free space,
contiguous to the one already allocated, is not available. This behavior is not
reasonable since sufficient contiguous resources, that can satisfy the request,
are available at a different location.
This patch provides the ability to expand and relocate a allocated resource.
v2: Changelog: Fixed size calculation in pci_reassign_resource()
v3: Changelog : Split this patch. The resource.c changes are already
upstream. All the pci driver changes are in here.

PCI: honor child buses add_size in hot plug configuration
git commit
c8adf9a3e873eddaaec11ac410a99ef6b9656938
"PCI: pre-allocate additional resources to devices only after
successful allocation of essential resources."
fails to take into consideration the optional-resources needed by children
devices while calculating the optional-resource needed by the bridge.
This can be a problem on some setup. For example, if a hotplug bridge has 8
children hotplug bridges, the bridge should have enough resources to accomodate
the hotplug requirements for each of its children hotplug bridges. Currently
this is not the case.
This patch fixes the problem.

PCI: Set PCI-E Max Payload Size on fabric
On a given PCI-E fabric, each device, bridge, and root port can have a
different PCI-E maximum payload size. There is a sizable performance
boost for having the largest possible maximum payload size on each PCI-E
device. However, if improperly configured, fatal bus errors can occur.
Thus, it is important to ensure that PCI-E payloads sends by a device
are never larger than the MPS setting of all devices on the way to the
destination.
This can be achieved two ways:
- A conservative approach is to use the smallest common denominator of
the entire tree below a root complex for every device on that fabric.
This means for example that having a 128 bytes MPS USB controller on one
leg of a switch will dramatically reduce performances of a video card or
10GE adapter on another leg of that same switch.
It also means that any hierarchy supporting hotplug slots (including
expresscard or thunderbolt I suppose, dbl check that) will have to be
entirely clamped to 128 bytes since we cannot predict what will be
plugged into those slots, and we cannot change the MPS on a "live"
system.
- A more optimal way is possible, if it falls within a couple of
constraints:
* The top-level host bridge will never generate packets larger than the
smallest TLP (or if it can be controlled independently from its MPS at
least)
* The device will never generate packets larger than MPS (which can be
configured via MRRS)
* No support of direct PCI-E <-> PCI-E transfers between devices without
some additional code to specifically deal with that case
Then we can use an approach that basically ignores downstream requests
and focuses exclusively on upstream requests. In that case, all we need
to care about is that a device MPS is no larger than its parent MPS,
which allows us to keep all switches/bridges to the max MPS supported by
their parent and eventually the PHB.
In this case, your USB controller would no longer "starve" your 10GE
Ethernet and your hotplug slots won't affect your global MPS.
Additionally, the hotplugged devices themselves can be configured to a
larger MPS up to the value configured in the hotplug bridge.
To choose between the two available options, two PCI kernel boot args
have been added to the PCI calls. "pcie_bus_safe" will provide the
former behavior, while "pcie_bus_perf" will perform the latter behavior.
By default, the latter behavior is used.
NOTE: due to the location of the enablement, each arch will need to add
calls to this function. This patch only enables x86.
This patch includes a number of changes recommended by Benjamin
Herrenschmidt.

Note: When upper layer's read/write request cannot be fulfilled, the block
layout driver shouldn't silently mark the page as error. It should do
what can be done and leave the rest to the upper layer. To do so, we
should set rdata/wdata->res.count properly.
When upper layer re-send the read/write request to finish the rest
part of the request, pgbase is the position where we should start at.

pnfsblock: cleanup_layoutcommit
In blocklayout driver. There are two things happening
while layoutcommit/cleanup.
1. the modified extents are encoded.
2. On cleanup the extents are put back on the layout rw
extents list, for reads.
In the new system where actual xdr encoding is done in
encode_layoutcommit() directly into xdr buffer, these are
the new commit stages:
1. On setup_layoutcommit, the range is adjusted as before
and a structure is allocated for communication with
bl_encode_layoutcommit && bl_cleanup_layoutcommit
(Generic layer provides a void-star to hang it on)
2. bl_encode_layoutcommit is called to do the actual
encoding directly into xdr. The commit-extent-list is not
freed and is stored on above structure.
FIXME: The code is not yet converted to the new XDR cleanup
3. On cleanup the commit-extent-list is put back by a call
to set_to_rw() as before, but with no need for XDR decoding
of the list as before. And the commit-extent-list is freed.
Finally allocated structure is freed.
