staging/lustre: get rid of obd_* typedefs
We have a bunch of typedefs for common things that made no sense
and hid the actual type from plain view.
Replace them with proper uXX or sXX types.
Exception is in lustre_idl.h where
they are replaced with __uXX and __sXX to be able to be included
in userspace

staging/lustre/osc: Update inode timestamp for lockless IO as well
Removed the checks for oi_lockless from osc_io_read_start() and
osc_io_write_start(). This patch also removes the unnecessary call to
cl_object_attr_get() in osc_io_write_start() before calling
cl_object_attr_set()

staging/lustre: restore __GFP_WAIT flag to memalloc calls
In Lustre 2.4, the flags passed to the memory allocation functions are
translated from CFS enumeration values types to the kernel GFP
values by calling cfs_alloc_flags_to_gfp(). This function adds
__GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when
the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was
removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx.
This means that most memory allocation calls are missing the
__GFP_WAIT flag. The result is that Lustre experiences more ENOMEM
errors, many of which the higher levels of Lustre do not handle
robustly.
Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces
__GFP_IO with GFP_NOFS.
Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in
Lustre 2.4 so it has never been used with __GFP_WAIT.

lustre/clio: honor O_NOATIME
Add a ci_noatime bit to struct cl_io. In ll_io_init() set this bit if
O_NOATIME is set in f_flags. Ensure that this bit is propagated down
to lower layers. In osc_io_read_start() don't update atime if this bit
is set. Add sanity test 39n to check that passing O_NOATIME to open()
is honored.

staging/lustre: fix build error on non-x86 platforms
dump_trace() is only available on X86. Without it, Lustre's own
watchdog is broken. We can only dump current task's stack.
The client-side this code is much less likely to hit deadlocks and
it's probably OK to drop this altogether, since we hardly have any
ptlrpc threads on clients, most notable ones are ldlm cb threads
that should not really be blocking on the client anyway.
Remove libcfs watchdog for now, until the upstream kernel watchdog
can detect distributed deadlocks and dump other kernel threads.

staging: add Lustre file system client support
Lustre is the most deployed distributed file system
in the HPC (High Performance Computing) world. The patch
adds its client side support.
The code is not very clean and needs to live in drivers/staging
for some time for continuing cleanup work. See
drivers/staging/lustre/TODO for details.
The code is based on Lustre master commit faefbfc04
commit faefbfc0460bc00f2ee4c1c1c86aa1e39b9eea49
