  Hi,

The function ABI change seems to be stable but is exposing existing
backend issues pertinent to wN regs. Hence this series to first address
those and then pursue ABI fixes.

 - Patch 1/3 is desirable, 2/3 is a bug fix and both can go in now.
 - Patch 3/3 needs more work but posting anyways due to same area.

Please take a look.

Thx,
-Vineet
