I think you have most of the Spectre stuff aside from microcode
supported fixes.  These are still missing on the 4.4 branch though:

8fa80c503b48 nospec: Move array_index_nospec() parameter checking into separate macro
1d91c1d2c80c nospec: Kill array_index_nospec_mask_check()

I think there may also be some extra uaccess functions that didn't get
the nospec treatment.

I'll probably look into backporting the microcode stuff to the older
branches (4.4, then 3.16 and 3.2) at some point.

Ben.
