The change happens to break MIPS quite thoroughly, since MIPS is using different pointers when accessing PCPU area locally and when doing iterations using cpu_to_cpuid array. I therefore officially am requesting this change to be reverted until reasonable solution is found to unbreak architectures that use wired TLBs to access local per-CPU data. -- Alexander Kabaev
