Try to write dual-phase retry protocol limits to BUSY_TIMEOUT register.
- The dual-phase retry protocol is optional to implement, and if not
supported, writes to the dual-phase portion of the register will be
ignored. We try to write the original 1394-1995 default here.
- In the case of devices that are also SBP-3-compliant, all writes are
ignored, as the register is read-only, but contains single-phase retry of
15, which is what we're trying to set for all SBP-2 device anyway, so this
write attempt is safe and yields more consistent behavior for all devices.
See section 8.3.2.3.5 of the 1394-1995 spec, section 6.2 of the SBP-2 spec,
and section 6.4 of the SBP-3 spec for further details.

Write directly in big endian instead of byte-swapping after the fact.
This saves a few conversions, lets gcc use constant endianess
conversions where possible, and enables deeper endianess annotation.

The following patch limits the node speed to the host interface speed,
before using it.
Signed-off-by: Philippe De Muyter <phdm@macqel.be>
It should actually suffice to do this only for the local node's
speedcap[]. But there is another bug in the speed calculation:
The local node's speed is not correctly propagated to the speeds
which are to be used to access remote nodes.

These drivers don't need to match any unit_directory type device.
They just need the id_table for module autoloading per module alias.
Not binding any of these drivers allows special-purpose drivers with
similar or same IDs to bind to devices. This currently only benefits
out-of-tree drivers; on the other hand it is in no way detrimental to
in-tree drivers.

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
code are just wrong, there are too many different devices out there with
different numbers of endpoints. We need to just be sticking with the
device ids instead of trying to catch this kind of thing. It broke too
many different devices.
This fixes a large number of usb-serial devices to get them working
properly again.

x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
This patch introduces struct pci_sysdata to x86 and x86-64, and
converts the existing two users (NUMA, Calgary) to use it.
This lays the groundwork for having other users of sysdata, such as
the PCI domains work.
The Calgary bits are tested, the NUMA bits just look ok.
replaces pcibios_scan_root by pci_scan_bus_parented...
but in pcibios_scan_root we have a check about scanned busses.

mb_cache_entry_alloc() was allocating cache entries with GFP_KERNEL. But
filesystems are calling this function while holding xattr_sem so possible
recursion into the fs violates locking ordering of xattr_sem and transaction
start / i_mutex for ext2-4. Change mb_cache_entry_alloc() so that filesystems
can specify desired gfp mask and use GFP_NOFS from all of them.

As shown by Gurudas Pai recently, we can put hugepages into the surplus
state (by echo 0 > /proc/sys/vm/nr_hugepages), even when
/proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to
allow the original goal (shrink the static pool to 0) to succeed (we are
converting hugepages to surplus because they are in use). However, the
documentation does not accurately reflect this case. Update it.
