cdd04d98f6 [DCCP]: Convert do_gettimeofday() to getnstimeofday().
What do_gettimeofday() does is to call getnstimeofday() and
to convert the result from timespec{} to timeval{}.
We do not always need timeval{} and we can convert timespec{}
when we really need (to print).

457c4cbc5a [NET]: Make /proc/net per network namespace
This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

9e367d8592 jprobes: remove JPROBE_ENTRY()
AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything
useful - so remove it ..

I've left a do-nothing version so that out-of-tree jprobes code will still
compile without modifications.

fddc2feb94 [CCID3]: More to see in dccp_probe
This adds a few more fields of interest to /proc/net/dccpprobe, the following output ensues:

1           2          3           4     5  6     7   8        9        10   11
sec.usec   src:sport   dst:dport   size  s  rtt   p   X_calc   X_recv   X    t_ipi

Also made the formatting consistent.

9a32144e9d [PATCH] mark struct file_operations const 7
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

e41542f516 [DCCP]: Introduce dccp_probe
This adds DCCP probing shamelessly ripped off from TCP probes by Stephen
Hemminger.

I've put in here support for further CCID3 variables as well.
Andrea/Arnaldo might look to extend for CCID2.
