Trivial fix: mark the buffer to hexdump as const so callers could avoid
casting their const buffers when calling print_hex_dump().
The patch is really trivial and I suggest to consider it as a fix
(it fixes GCC warnings) and push it to current tree.

Small patch to H-TCP from Douglas Leith.
Fix estimation of maxRTT. The original code ignores rtt measurements
during slow start (via the check tp->snd_ssthresh < 0xFFFF) yet this
is probably a good time to try to estimate max rtt as delayed acking
is disabled and slow start will only exit on a loss which presumably
corresponds to a maxrtt measurement. Second, the original code (via
the check htcp_ccount(ca) > 3) ignores rtt data during what it
estimates to be the first 3 round-trip times. This seems like an
unnecessary check now that the RCV timestamp are no longer used
for rtt estimation.

conntracks
ctnetlink must return EEXIST for existing nat'ed conntracks instead of
EINVAL. Only return EINVAL if we try to update a conntrack with NAT
handlings (that is not allowed).

recent_seq_open()
If the call to seq_open() returns != 0 then the code calls
kfree(st) but then on the very next line proceeds to
dereference the pointer - not good.

hash table
The LSM domain mapping head table pointer was not being referenced via the RCU
safe dereferencing function, rcu_dereference(). This patch adds those missing
calls to the NetLabel code.

[SPARC64]: Fix memory leak when cpu hotplugging.

Every time a cpu is added via hotplug, we allocate the per-cpu MONDO
queues but we never free them up. Freeing isn't easy since the first
cpu gets this memory from bootmem.
Therefore, the simplest thing to do to fix this bug is to allocate the
queues for all possible cpus at boot time.

refine the granularity of negative nice level tasks: let them
reschedule more often to offset the effect of them consuming
their wait_runtime proportionately slower. (This makes nice-0
task scheduling smoother in the presence of negatively
reniced tasks.)
