Merge branch 'rhashtable_remove_shift'

Herbert Xu says:

====================
rhashtable: Kill redundant shift parameter

I was trying to squeeze bucket_table->rehash in by downsizing
bucket_table->size, only to find that my spot had been taken
over by bucket_table->shift.  These patches kill shift and makes
me feel better :)

v2 corrects the typo in the test_rhashtable changelog and also
notes the min_shift parameter in the tipc patch changelog.
