[PATCH] fix alloc_large_system_hash() roundup
The "rounded up to nearest power of 2 in size" algorithm in
alloc_large_system_hash is not correct. As coded, it takes an otherwise
acceptable power-of-2 value and doubles it. For example, we see the error
if we boot with thash_entries=2097152 which produces a hash table with
4194304 entries.
