  * Florian: Bringing back my pagesize patch series. Two options for 32-bit Arm, would appreciate a review from Wilco. Hardcode 4K pages on 32-bit arm.
   * Wilco: Looks OK to me. In the past when we tried running plain 32-bit images on a 64k system, so that is historically the case.
   * Carlos: Is there an industry that will continue to use 32-bit Arm, but those have 4k pages.
   * Wilco: Larger servers won't be able to run 32-bit code in the future.
  * Sachin: Following in the footsteps of Peter and working to be a maintainer for IBM.
   * Sachin: Worked on a vector engine in the past. Also work on nx hardware compression library. Likewise papi for hardware events for power.
