Pull requests for [TXYZ] updating the Amazon ENA network driver to the
latest upstream version (1.2.0k).

All cherry-picks from mainline and net-next, touching only the ENA driver --
except that Trusty needs one additional lib commit from from mainline (a
simple context backport):

 T--- 3464452 lib: devres: add a helper function for ioremap_wc
 
 ---Z b1669c9 net/ena: use napi_complete_done() return value
 TXYZ 90a6c99 net: ena: remove superfluous check in ena_remove()
 --YZ da6f4cf net/ena: switch to pci_alloc_irq_vectors

I've only looked at the zesty updates. Based on those, the changes are
all cherry picks from upstream or net-next and affect only the ENA
driver.

Acked-by: Seth Forshee <[hidden email]>

I also applied relevent patches to artful/master-next and
unstable/master.
