292b9dab40 net: cavium: liquidio: Remove deprecated create_workqueue 
alloc_workqueue replaces deprecated create_workqueue().

A dedicated workqueue has been used since the workitem viz
(&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status)
is involved in a brief poll routine for checking transmit queue status
and is an intergral part of normal device operation.
WQ_MEM_RECLAIM has been set to guarantee forward progress under memory
pressure, which is a requirement here.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.

flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty.

smatch detected a suspicious looking bitop condition:

drivers/net/ethernet/cavium/liquidio/lio_main.c:2529
  handle_timestamp() warn: suspicious bitop condition

(skb_shinfo(skb)->tx_flags | SKBTX_IN_PROGRESS is always non-zero,
so the logic is definitely not correct.  Use & to mask the correct
bit.

08a965ec93 net: cavium: liquidio: Return correct error code 
The return value of vmalloc on failure of allocation of memory should
be -ENOMEM and not -1.

Found using Coccinelle. A simplified version of the semantic patch
used is:

//<smpl>
@@
expression *e;
identifier l1;
position p,q;
@@

e@q = vmalloc(...);
if@p (e == NULL) {
...
goto l1;
}
l1:
...
return -1
+ -ENOMEM
;
//</smpl

The single call site of the containing function checks whether the
returned value is -1, so this check is changed as well. The single call
site of this call site, however, only checks whether the value is not 0,
so no further change was required.

3) Liquidio now supports 64 bit only, modified Kconfig accordingly.
4) Fix some code alignment issues based on kernel build warnings.
