Hi Sasha,

We need to keep track of which Spectre patches have been backported
and which haven't. David Long has been doing the backport work,
which doesn't include all the patches in my present spectre branch.
You've picked up the last five, meaning there's a bunch in the middle
of the entire series which haven't yet been considered - for example,
the Spectre variant 1.1 patches.

I'll drop all the ones you pointed out from my branches. Sometimes it's
difficult to tell if a certain patch is part of the spectre fix.

The entire series of 32-bit ARM Spectre patches can be listed in
mainline via:

$ git log v4.16..383fb3ee8024

where almost all of those need to be applied to stable kernels, with
possible manual back-porting where they don't apply.

Is it something that will be backported at some point?
