This is a follow-up on [2], which addresses both the O(n) SGI injection
issue, and cleans up a number of embarassing bugs steaming form the
vcpuid/vcpu_idx confusion.
See the changelog below for details.
Oliver, assuming that you haven't changed your mind and that
nobody shouts, feel free to queue this in -next.
* From v2 [2]:
- Killed a number of online_vcpus comparisons, which didn't make
much sense (Zenghui)
- Added missing commit logs (oops)
- Fixed some comments
- Collected RBs, with thanks
* From v1 [1]:
- Added a bunch of patches fixing the vcpu_id[x] ambiguity
- Added a documentation update spelling out some extra ordering requirements
- Collected RBs/TBs, with thanks
