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.
This avoids unnecessary use of usb_alloc_urb() & usb_free_urb() if kzalloc()
returns NULL.
Also, makes the code better structured & easier to understand.

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.

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

occurring while the bulk I/O size is larger than
PTLRPC_MAX_BRW_SIZE.

The patch also improves obdfilter-survey to handle the

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_*
  directly in mdt_attr_valid_xlate() instead.
- improve sanityn.sh test_23().

on what tools are being used on the filesystem.

To ensure all the dirty on remote clients being flushed back on

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.

ptlrpcd_add_req() will wake_up other process, do not hold a spinlock
before calling ptlrpcd_queue_work()->ptlrpcd_add_req().

If current process is allocating memory, memory shrinker could get to
osc_lru_del(), don't call osc_lru_shrink() further since it could
lead a long calling chain.

Use static string OES_STRINGS in OSC_EXTENT_DUMP() to reduce stack
footprint.

Alloc crattr on heap for osc_build_rpc() to reduce stack footprint.

In ldlm_lock_decref_internal() when l_lvb_data is freed to
reduce memory consumption, LDLM_FL_LVB_READY is not
cleared, so later when the lock is reused lvb is not
updated. But clearing LDLM_FL_LVB_READY forces layout refetch
at each file access, so the better is to remove the optimization.
The use case is after a restore in HSM.
