ef2e0f55ec staging/lustre: Remove mds/ost capabilities support
Client capabilities is an outdated feature that never worked properly,
so let's get rid of the client support since modern servers
don't have this support either.

The patch is big, but since it just removes one large feature,
so it's hopefully easy to verify.

8c85bd76d3 staging/lustre/llog: remove unused server code
Most of the code in llog.c and llog_cat.c is completely unused
on the client and can be removed, as a preparation for removing
the dt_object code.

Two tricky parts are:

 - In llog_cat_close(), we rely on the fact that llh_flags never
   contains LLOG_F_ZAP_WHEN_EMPTY, because nobody ever sets that
   flag.

 - In llog_read_header(), we check the return value of the lpi_cb
   callback, and again we know that it cannot be LLOG_PROC_BREAK
   or LLOG_DEL_RECORD and can remove the respective code path.

219e6de627 staging/lustre: use 64-bit times for request times
All request timestamps and deadlines in lustre are recorded in time_t
and timeval units, which overflow in 2038 on 32-bit systems.

In this patch, I'm converting them to time64_t and timespec64,
respectively. Unfortunately, this makes a relatively large patch,
but I could not find an obvious way to split it up some more without
breaking atomicity of the change.

Also unfortunately, this introduces two instances of div_u64_rem()
in the request path, which can be slow on 32-bit architectures. This
can probably be avoided by a larger restructuring of the code, but
it is unlikely that lustre is used in performance critical setups
on 32-bit architectures, so it seems better to optimize for correctness
rather than speed here.

70513c5d17 staging/lustre: use jiffies_to_*() instead of cfs_duration_usec
The cfs_duration_usec() function has a timeval as its output, which we
want to avoid in general because of the y2038 problem.

There are only two locations remaining in lustre, so we can for now
replace one with jiffies_to_timeval(), which is a generic kernel function
that does the same thing, the other can just use jiffies_to_usecs()
and completely avoid the timeval.

This is not a full solution yet, but it's a small step that lets us
build a larger portion of lustre without this reference to timeval in
a header file, and avoid triggering automated checking tools that wants
to warn about timeval.

65f28840e4 staging/lustre: tracefile: document seconds overflow
The lustre tracefile has a timestamp defined as

       __u32 ph_sec;
       __u64 ph_usec;

which seems completely backwards, as the microsecond portion of
a time stamp will always fit into a __u32 value, while the second
portion will overflow in 2038 or 2106 (in case of unsigned seconds).

Changing this would unfortunately change the format in an incompatible
way, breaking all existing user space tools that access the data.

This uses ktime_get_real_ts64() to replace the insufficient
do_gettimeofday() and then truncates the seconds portion to
an u32 type, along with comments to explain the result.

A possible alternative would be the use of ktime_get_ts64() to
read a monotonic timestamp that never overflows, but this would
trigger a check in user space 'hdr->ph_sec < (1 << 30)' that
attempts to ensure that the values are within a reasonable range.

45efd655b1 staging/lustre: obd: remove unused data structures
We want to get rid of all uses of time_t, and it turns out
that obd.h contains a bunch of them that are completely unused.

This removes those structures, along with a couple of other
structures and functions in the same file that also turned
out to be unused.

46c360f9d3 staging/lustre: use 64-bit inode timestamps internally
Lustre has 64-bit timestamps in its network data structures, but
on 32 bit systems, it converts them directly into time_t, which is
32 bit wide.

This changes the code to use 64-bit time stamps for files. The Linux
VFS code still uses time_t though, and will be changed in a separate
patch series.

9f088dba3c staging/lustre: use jiffies for lp_last_query times
The recently introduced lnet_peer_set_alive() function uses
get_seconds() to read the current time into a shared variable,
but all other uses of that variable compare it to jiffies values.

This changes the current use to jiffies as well for consistency.
