The name includes irq_res->start which of type resource_size_t not integer.
We could in theory use %pa for this but then it would be in hex and also
that causes a warning about incorrect types anyway.  Hence just
use the irq local variable we assigned the line above.

Add support for Octeon USB HCD. Tested on EdgeRouter Lite with USB
mass storage.

The driver has been extracted from GPL sources of EdgeRouter Lite firmware
(based on Linux 2.6.32.13). Some minor fixes and cleanups have been done
to make it work with 3.10-rc3.

Check to see if allocation by kzalloc() or usb_alloc_urb() was unsuccessful
immediately after the allocation. Exit from the function can be right at that
point in case of allocation failure.

The timeout detection implemented in this driver isn't very
robust. Although the USB interrupt transfer was successful,
the polling thread often reported timeouts because the 50ms
had expired before it got scheduled, and the SD card wasn't
detected. Increasing it to 100ms, as used in other places of
this driver, makes it work.

This patch checks the number of bulk I/O RPC pages with
PTLRPC_MAX_BRW_PAGES in ofd_preprw() to avoid
LASSERT(iobuf->dr_npages < iobuf->dr_max_pages) occurring
while larger I/O size is specified.

The patch also fixes echo_client_prep_commit() to reuse
the env context so as to avoid LASSERT(info->fti_exp == NULL)
occurring while the bulk I/O size is larger than
PTLRPC_MAX_BRW_SIZE.

The patch also improves obdfilter-survey to handle the
case while interoprating with old server.

To make atime update properly between 1.8 client and 2.x server,
this patch includes the following fixes:
- if MDS_ATTR_xTIME is set without MDS_ATTR_xTIME_SET and the client
  does not have OBD_CONNECT_FULL20, convert it to LA_xTIME in
  mdt_setattr_unpack().
- set both MDS_ATTR_xTIME | MDS_ATTR_xTIME_SET for timestamps in
  ll_prepare_close(). This allows us to fix the server-side timestamp
  setting in the future.
- remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_*

- improve sanityn.sh test_23().

In order to avoid compatibility issues with older ChangeLog consumers,
change the new CL_LAYOUT record to use the value previously assigned
to CL_IOCTL.  The CL_IOCTL type was never used anywhere, and it didn't
really make any sense as a ChangeLog record, since it could really
mean anything at all.

The changelog_show_cb() function is renamed to changelog_kkuc_cb(),
since it is really about consuming the ChangeLog and passing it up to
the kernel-user-coms interface.  At some point we should consider to
implement a DBUS-based ChangeLog interface as well.

The changelog_kkuc_cb() "sanity check" on cr_type was removed, since
there is no reason the client kernel needs to know every record type
that is being passed to userspace.  It is up to the client tool to
determine what records that it can process.
