commit a09022a09e1a79b3f9574993993bfad803b32596 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> AuthorDate: Thu May 23 00:55:34 2024 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Wed Jun 19 13:00:06 2024 +0100 x86/boot: Collect the Raw CPU Policy earlier on boot This is a tangle, but it's a small step in the right direction. In the following change, xstate_init() is going to start using the Raw policy. calculate_raw_cpu_policy() is sufficiently separate from the other policies to safely move like this. No functional change.
