Ok, I have tried to go through the patches, and I don't see anything
horrible, but honestly, at this point I'd rather leave it for 4.16.
We're presumably going to have to back-port these things anyway for
the LTS releases, and they're still getting comments and small fixes
after the merge window is over. I'd rather have people feel like they
can take the time to just get it all clean and finished (and as much
testing as possible) than start merging things aggressively.
I'll happily take some of the cleanup and prep patches if people want
those to go in separately. The unwinder and stack overflow patches
seem to be entirely unrelated to the actual changes that are
introduced, for example, and came out of debugging them. And the
sysenter stack patch seems a nice cleanup that actually removes
special cases.
Comments?
Linus
