| Message-ID | <qOjzX-Lp-7@gated-at.bofh.it> |
There is no need for request bits to differ across architectures. Only a handful of them are architecture-independent, the others can all share bits 8-31 with overlap. Leaving room for more architecture-independent bits means that actually no bits are freed, but the cleanup is useful anyway IMO.
