* pci/scan-bridge:
PCI: Don't scan random busses in pci_scan_bridge()
PCI: Check for child busses which use more bus numbers than allocated
PCI: Remove pci_fixup_parent_subordinate_busnr()
PCI: Make sure bus number resources stay within their parents bounds
PCI: Use request_resource_conflict() instead of insert_ for bus numbers
PCI: Assign CardBus bus number only during the second pass
PCI: Clarify the "scan anyway" comment in pci_scan_bridge()
PCI: Increment max correctly in pci_scan_bridge()
When assigning a new bus number in pci_scan_bridge we check whether
max+1 is free by calling pci_find_bus. If it does already exist then we
assume that we are rescanning and that this is the right bus to scan.
This is fragile. If max+1 lies outside of bus->busn_res.end then we will
rescan some random bus from somewhere else in the hierachy. This patch
checks for this case and prints a warning.

pci_scan_child_bus can (potentially) return a bus number higher than the
subordinate value of the child bus. Possible reasons are that bus numbers
are reserved for SR-IOV or for CardBus (SR-IOV is done without checks and
the CardBus checks are sketchy at best).
We clamp the returned value to the actual subordinate value and print a
warning if too many bus numbers are reserved.

The function has no effect.
If pcibios_assign_all_busses() is not set then the function does nothing.
If it is set then in pci_scan_bridge we are always in the branch where
we assign the bus numbers ourselves and the subordinate values of all
parent busses will be set to 0xff since that is what they inherited from
their parent bus and ultimately from the root bus.

Right now we use 0xff for busn_res.end when probing and later reduce it to
the value that is actually used. This does not work if a parent bridge has
already a lower subordinate value. For example during hotplug of a new
bridge below an already-configured bridge the following message is printed
from pci_bus_insert_busn_res():
pci_bus 0000:06: busn_res: can not insert [bus 06-ff] under [bus 05-9b] (conflicts with (null) [bus 05-9b])
This patch clamps the bus range to that of the parent and also ensures that
we do not exceed the parents range when assigning the final subordinate
value.
We also check that busses configured by the firmware fit into their parents
bounds.

This patch fixes two small issues:
- If pci_add_new_bus() fails, max must not be incremented. Otherwise
an incorrect value is returned from pci_scan_bridge().
- If the bus is already present, max must be incremented. I think
that this case should only be hit if we trigger a manual rescan of a
CardBus bridge.

The AMD early_fill_mp_bus_info() already allocates a struct pci_root_info
for each PCI host bridge it finds, and that structure contains the NUMA
node number. We don't need to keep the same information in the
mp_bus_to_node[] table.
This adds x86_pci_root_bus_node(), which returns the NUMA node number, or
NUMA_NO_NODE if the node is unknown.
Note that unlike get_mp_bus_to_node(), x86_pci_root_bus_node() only works
for root buses. For example, if amd_bus.c finds a host bridge on node 1 to
[bus 00-0f], get_mp_bus_to_node() returns 1 for any bus between 00 and 0f,
but x86_pci_root_bus_node() returns 1 for bus 00 and NUMA_NO_NODE for buses
01-0f.

Pull parisc updates from Helge Deller:
"The three major changes in this patchset is a implementation for
flexible userspace memory maps, cache-flushing fixes (again), and a
long-discussed ABI change to make EWOULDBLOCK the same value as
EAGAIN.
parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
to keep HP-UX compatibility. Since we will probably never implement
full HP-UX support, we prefer to drop this compatibility to make it
easier for us with Linux userspace programs which mostly never checked
for both values. We don't expect major fall-outs because of this
change, and if we face some, we will simply rebuild the necessary
applications in the debian archives"

HPFS needs to load 4 consecutive 512-byte sectors when accessing the
directory nodes or bitmaps. We can't switch to 2048-byte block size
because files are allocated in the units of 512-byte sectors.
Previously, the driver would allocate a 2048-byte area using kmalloc,
copy the data from four buffers to this area and eventually copy them
back if they were modified.
In the current implementation of the buffer cache, buffers are allocated
in the pagecache. That means that 4 consecutive 512-byte buffers are
stored in consecutive areas in the kernel address space. So, we don't
need to allocate extra memory and copy the content of the buffers there.
This patch optimizes the code to avoid copying the buffers. It checks
if the four buffers are stored in contiguous memory - if they are not,
it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free
space using statfs. This patch changes it so that hpfs scans the
bitmaps only once, remembes the free space and on next invocation of
statfs it returns the value instantly.
New versions of wine are hammering on the statfs syscall very heavily,
making some games unplayable when they're stored on hpfs, with load
times in minutes.
This should be backported to the stable kernels because it fixes
user-visible problem (excessive level load times in wine).
